  • How to find climate data and science the Trump administration doesn’t want you to see

    nigelj at 07:34 AM on 20 February, 2025

    Lets get directly to the point. Americas current executive government is removing and hiding data and information for no defensible reason. Its no different in principle to ancient organisations who burned or banned books they didnt like. Historical example include books by Copernicus and Galileo. And its no different to the way fascist dictatorships control and limit information flows. This is not The Democrats censoring the worst types of hate speech. Its the new administration banning or hiding of of vast amounts of data, facts, theories, opinions, and other information. Its the total destruction of free speech.

  • Sabin 33 #12 - Do solar panels work in cold or cloudy climates?

    Bob Loblaw at 02:09 AM on 24 January, 2025

    Upstream, in comment 4, I talked about some of the aspects of solar panel installation and orientation. Words are nice, but pictures are often better, so I've graphed out some data to show some difference between clear/cloudy, winter/summer, and horizontal/tilted measurements of solar radiation.


    The following graphs are a continental location, at about 50°N latitude.


    All radiation graphs show five different measurements:



    • The "Direct" measurement is "direct normal" - an instrument pointed directly at the sun, with a narrow field of view.

    • "Diffuse" is the radiation on a horizontal surface of just the sky - direct sun blocked.

    • "Global" is a full sky view (direct plus diffuse) on a horizontal surface.

    • "Titled" is also direct plus diffuse, but at a 50° tilt to the south, so it sees some sky and some ground.

    • "Reflected" is the same type of instrument as "Global", but upside-down so it sees all the solar radiation being reflected off the ground surface.


    The first graph is a clear day at the beginning of January. Direct radiation peaks at over 900W/m2, and diffuse radiation is less than 100W/m2. Because the sun is low in the sky, the global reading is much less than the direct - peaking slightly over 300 W/m2. The tilted sensor, though, peaks at over 800 W/m2 - not only is it pointing much closer to the sun, but it also sees a lot of ground that is very bright. The reflected reading peaks at over 200W/m2 - the ground is snow covered, reflecting about 75% of the global signal, so much brighter than the deep blue sky of the diffuse signal.


    Clear sky winter radiation


     


    Clearly, a tilted solar panel would produce much more power than a horizontal one. We can see why when we look at the solar elevation angle (how high about the plane of the panel the sun is located). This graph shows the elevation above a horizontal surface (global instrument) and tilted surface. The sun is barely 20° above the horizon of the horizontal sensor, but is over 60° above the tilted sensor's "horizon". Note that the daylight period is only about 8 hours - elevation>0° for the horizontal view. Even though the titled sensor has an elevation >0° for much longer, those "extra" hours mean nothing, as the view of the sun is blocked by the earth!


    Winter solar elevation


     


    The next day, cloud moved in. Direct radiation is zero, except for a brief period in early afternoon when the clouds thinned enough to let a bit of direct sun through. The four other lines are, from highest to lowest, tilted, Global and Diffuse (virtually tied), and Reflected. With no direct sun, and a snow-covered surface that reflects most of the solar radiation, there isn't much difference between the horizontal and tilted readings.


    Cloudy sky winter radiation


     


    Note that for the horizontal sensor (global) the cloudy day is not much lower than the clear day. It peaks around 250W/m2, compared to a little over 300W/m2 on the clear day.


    What about summer? Here is a "mostly" clear day in early July. Direct beam peaks only slightly higher than in January, but global radiation is much higher because of the higher solar elevation. The titled sensor peaks a little higher than global - it's tilt is no longer much of an advantage over the global sensor, and the portion of ground it sees is now dark (reflecting only about 20% of the global). Diffuse is again <100W/m2.


    Clear sky summer radiation


    Daylight is now more like 16 hours, though, so daily totals will be quite different from January. We also see something odd in the tilted sensor - it peaks higher than the global (horizontal) sensor, but in early morning and late afternoon, it sees less than the global sensor. In fact, at the extremes it looks like it is only seeing the diffuse radiation - no direct.


    We can understand this by looking at the solar elevation again. Note that for the titled sensor, the sun "rises" much later and "sets" much earlier (elevation <0°) than for the global sensor. What is happening is that the sun rises in the NE and sets in the NW, so it is actually behind the tilted sensor, not in front of it.


    Summer solar elevation


     


    And lastly, we'll look at a cloudy summer day, right on the summer solstice. We do see some direct sun getting through in the afternoon, but we can see the cloudy period that covers most of the day. We see a substantial reduction in global before noon local time (compared to the clear day). After 12pm, we see a higher value for global as the cloud thins and a bit of direct radiation makes it through the clouds. During the cloudy period, the tilted sensor is not much different than the global one - both are seeing the same diffuse radiation.


    Cloudy sky summer radiation


     


    So, hopefully this helps illustrate some of the complexities related to solar panel installation and orientation. To refer back to the OP - no, cloudy skies does not mean "no solar energy". The OP is correct - the myth is busted.


    This is only one location, and a few days of data. And this level of data is not readily available for most locations. But it does illustrate that installation may be dependent on local factors such as amount of cloud, type of cloud, timing during the day, etc.

    OPOF @ 43:


    I agree that David-acct seems hell bent for leather to discredit Wallace et al, and is blocking out anything that might run counter to that preferred outcome.


    As for Ecker et al (the paper listed in the OP), what does it have to say about Wallace et al (2022 - the earlier version of Walalce et al)? Here is the only reference they make to Wallace et al:



    ....and the partisan gap in COVID-19 vaccination rates
    between Republicans and Democrats—which is now
    associated with a widening gap in mortality rates (Wallace
    et al., 2022)...



    Nothing more than mentioning an "association". They don't even try to call it a cause-effect relationship. Not proof. Not "shows". Just an "association".


    For David-acct, even an "association", a slight implication, is too much for him to bear. The mental gymnastics he is going through to try to find something that will stick to the wall is absolutely astounding.


    In comment 27, I gave a list of speculations as to why we see no evidence that David-acct has actually read the Wallace et al paper. I am going to add one more. Granted, this is a highly unlikely explanation, but it's not impossible, so here it goes:



    • David-acct is paid to troll web sites and try to inject uncertainty and doubt into climate science, Covid, etc.

    • He has a list of responses he has been directed to add to comments sections whenever certain key words show up.


      • Whenever misinformation is mentioned, he is supposed to cry "censorship!", and claim "both sides..." arguments.

      • Whenever Covid is mentioned, he is supposed to claim the studies are wrong.

      • He probably has been given a "cheat sheet" for talking points if Wallace et al is mentioned.


    • Since he can't read or understand any of the science in any of these sources, he just keeps returning to the same tired talking points ad nauseum. When his canned answers run out, he just rewords them and repeats...


    Now, as I said, this "paid troll" explanation is extremely unlikely, but it is possible and fits the pattern. On the other hand, perhaps he is just arguing in his spare time.


    Of course, as he takes all these hits that destroy his arguments, he keeps claiming "tis but a scratch". Tell you what, David-acct: why don't we "call it a draw"???

    Bob Loblaw,


    David-acct certainly appears to exhibit the behaviours of an unwitting victim of Morton's Demon.


    However, I am not inclined to reconsider my update @31.


    I am inclined to believe that they are likely aware of, and understand, that they are raising unreasonable doubts ... perhaps hoping to appeal to Others who are unwittingly possessed by Morton's Demon.


    I had originally been overly-considerate in my comment @7 by suggesting that they were perhaps unwittingly presenting misunderstandings.


    The opening statement of their comment @2, "I agree that misinformation is a problem. However, calls to stop misinformation are essentially calls for censorship.", followed by the unreasonable claim that the Wallace et al 2022 study was misinformation, appears to be a deliberate attempt to unjustifiably discredit or dismiss the Ecker et al study.


    I would be inclined to change my mind if David-acct openly declared their full agreement with the Ecker et al study except for having some extremely minor, and possibly incorrect, doubts about Wallace et al.

    OPOF @ 39:


    That CBC story about the cancellation of The Penthouse's X account is priceless.


    It sounds to me like X would benefit from being bought by an individual who takes free speech seriously, and wants to establish policies where everyone is free to express themselves, regardless of popularity. We don't want censorship!


    [What's that? Oh, right. I forgot about that. Well, ignore that request.]


    In addition to the link on motivated reasoning, it's worth reposting the link to Morton's Demon.

    There is a follow-up report from NPR for the item I linked in my comment @15.


    NPR – Special Series - Untangling Disinformation: “Meta built a global fact-checking operation. Will it survive?” by Huo Jingnan, Shannon Bond, includes the following quote that is related to the evidence that David-acct repeatedly claimed that efforts to raise awareness about, and limit the harm done by, misinformation are ‘censorship’.


    In a video announcing the change, Zuckerberg said fact checking contributed to "censorship" on Meta's platforms and that fact checkers were too "politically biased." Fact checkers point out it is the company, not them, that decides how to police posts on Facebook and Instagram.


    "I'm just a simple European but…the United States seems to be the only country in the world where adding information is seen as censorship," said Maarten Schenk, Lead Stories chief operating officer and co-founder.


    "Far from censoring, fact-checkers add context," said Laura Zommer, co-founder and CEO of Factchequeado, a nonprofit, Spanish-language fact-checking site that is not part of Meta's program. "We never advocate for removing content. We want citizens to have better information so they can make their own decisions," she added.


    Note: The other items presented in the NPR – Special Series - Untangling Disinformation are very informative.

    nigelj @16,


    In addition to the concerns you mentioned that could be motivating Meta’s leadership to change how helpful its platforms are at limiting harm done, the NPR Item I linked in my comment @15 includes the following edited string of quotes:


    Repeating talking points long used by President-elect Donald Trump and his allies, in a video Zuckerberg said the company's content moderation approach resulted too often in "censorship".
    "After Trump first got elected in 2016, the legacy media wrote nonstop about how misinformation was a threat to democracy. We tried in good faith to address those concerns without becoming the arbiters of truth," Zuckerberg said. "But the fact checkers have just been too politically biased and have destroyed more trust than they've created, especially in the U.S."
    Meta set up one of the most extensive partnerships with fact checkers after the 2016 presidential election, in which Russia spread false claims on Facebook and other online platforms. The company created what has become a standard for how tech platforms limit the spread of falsehoods and misleading information.
    ...
    In recent years, fact checkers, researchers of false narratives, and social media content moderation programs have become targets of Republican-led Congressional probes and legal challenges.
    ...
    The president-elect and other Republicans have long accused Silicon Valley of harboring anti-conservative bias that has muzzled their speech online. Trump has accused Zuckerberg personally of election interference and threatened him with life in prison.
    ...
    Brendan Nyhan, a political scientist at Dartmouth College and longtime Meta observer, said it is distressing seeing business leaders "showing performative fealty" to the incoming administration.
    "Meta clearly perceives a great deal of political risk of being targeted," Nyhan said in an interview. "And the way Zuckerberg presented the announcements, and the timing, was obviously intended to play to a Republican audience."
    Some observers say Meta may be hoping for a lighter touch from regulators in the Trump administration.
    ...
    A sweeping antitrust case against Meta brought by the FTC and attorneys general from 48 states and territories during Trump's first term is set to go to trial in April. In a recent court filing, government lawyers wrote Mark Zuckerberg is expected to be among the first witnesses called to the stand.
    ...
    Research has shown that Republicans circulated more unfounded claims. One study also found that far right content was more engaging on Facebook, and that far-right sources known for spreading misinformation significantly outperformed non-misinformation sources. Data to definitively prove bias on a platform level is not available to researchers.
    ...
    The company's U.S. content moderation team will move from California to Texas. The move should "help us build trust to do this work in places where there is less concern about the bias of our teams," Zuckerberg said.
    ...
    Fact checkers who have worked with Meta for years pushed back against Zuckerberg's accusation of bias.
    "It was particularly troubling to see him echo claims of bias against the fact checkers because he knows that the ones that participated in his program were signatories of a code of principles that requires that they be transparent and nonpartisan," said Bill Adair, co-founder of the International Fact Checking Network. He founded PolitiFact, one of the first participants in Facebook's third party fact checker's program, which he left in 2020.
    "Meta, up until this morning, has always appreciated the independence of fact checkers," Adair said.

    Regarding Zuckerberg being accused of censorship, and his decision to cancel facebooks fact checking programme. His decision doesnt make any sense. Facebooks doesnt censor content except content that infringes the law, such as inciting violence, or sharing information related to child sexual abuse and virtually nobody is complaining about that. Facebook does moderate hate speech but that is unrelated to the issue of fact checking as such and doesnt appear to be the issue.The "fact checking" consists of attaching warnings and ratings to information and reducing the extent of its spread, by changing how its algorithms work to distribute information. This is not censorship because nothing is prohibited or deleted. Refer:


    https://www.facebook.com/formedia/blog/third-party-fact-checking-how-it-works


    Some sources claim Zuckerbergs decision not to do fact checking is because he is scared that Trump will attack his company in some way andt costs.


    Getting facebook users to fact check articles and rate them in some way could be chaos. They will probably end up with a list of different views and ratings all contradicing each other all written by amateurs and very hard for anyone to read them all or make sense of it.


    Zuckerberg is letting himself get pushed around, and it wont stop until his platform removes all ratings even those posted by users, and and removes all criticism of Republicans or their comments, because republicans  mistakingly believe criticism is the same as censoring their views.

    michael sweet @10,


    In addition to making-up misleading claims based on misunderstandings of raw data, David-acct has a history of claiming that efforts to help others learn about harmful misleading claims is a form of ‘censorship’ (Bob Loblaw @3 points this out). They try to redefine ‘censorship’ to include efforts to increase awareness and improve understanding. They also try to claim that efforts to increase awareness and improve understanding are also ‘misleading’ (David-acct @2 ends their misleading attack on “...the Wallace et al study 2022...” by incorrectly claiming that “It simply is another example of misinformation.”).


    If misleading claim makers like David-acct fail to succeed in claiming that exposing their misleading promotion of misunderstanding is ‘censorship’ or ‘misinformation’, then they are likely to shift to making-up claims that freedom of speech includes ‘the freedom from having the effectiveness of misleading made-up claims reduced by people learning from logical and evidence-based presentations of information and corrections'.


    Tragically, several popular communication platforms are shying away from responsibly justifiably exposing and correcting misleading claims (NPR item “Meta says it will end fact checking as Silicon Valley prepares for Trump” by Huo Jingnan, Shannon Bond, Bobby Allyn)


    The likes of Meta and X leadership appear to mistakenly believe that ‘communities driven by emotion-triggering (viral) popularity that can be significantly overwhelmed by harmfully misleading made-up claims’ will be effectively corrected, including having harm done by misleading claims being effectively undone and neutralized, by that same ‘community driven by emotion-triggering (viral) popularity that can be significantly overwhelmed by harmfully misleading made-up claims’. Logically, the evidence indicates that it is more likely that logical evidence-based (boring and long-winded) understandings will be popularly misunderstood to be misleading or deserve to be dismissed.

  • Skeptical Science New Research for Week #1 2025

    Bob Loblaw at 01:13 AM on 8 January, 2025

    Oh, my. More assertions from David-acct.


    First of all, let's look at "due diligence".



    • You started your diatribe in comment 2 saying "calls to stop misinformation are essentially calls for censorship". The paper listed in the OP, quoted by OPOF does not call "to stop misinformation" - it calls for not ignoring it and acting as if it has no effect. It's even in the title of the paper: "Why Misinformation Must Not Be Ignored". Reading the paper, I see nothing that represents a call to "stop misinformation".


      • You did not do due diligence to see if the paper actually called for stopping misinformation.

      • You made the same mistake a month ago, in the thread I linked to in comment 3 - misrepresenting a call to counter misinformation as a call to suppress it.

      • I'll respond with the same statement I made back then: Cries of "censorship!" are in reality attempts to silence counter-arguments. Typically, those that scream about censorship are the ones that want to suppress open discussion.


    • You have now provided a link that can be used to find eTable 1, mentioned in your comment 2.


      • First of all, that paper is not the same paper that was referenced in the Ecker paper listed in the OP.


        • The paper you referenced is more appropriately referred to as Wallace et al (2023). It is published in a journal titled JAMA Intern Med.

        • The paper listed in Ecker is from 2022, and it is an internal working paper for the organization that the authors (presumably) work at: the National Bureau of Economic Research.

        • The published version is clearly a later version of the same analysis, but it is not the same paper.

        • You have not done due diligence to make sure that the paper you referred to is the same paper that the Ecker group accessed.


      • eTable1 is found in the Supplemental Content tab, but you need to download a PDF to get to it.


        • eTable 1 is "death counts". It is not "excess deaths", which you referred to in your comment 2. Although you stated that eTable 1 provides "death rates", you then asked "How they could have possibly concluded republican excess death rates were higher than democrat excess deaths when the raw data shows otherwise."

        • In order to assess excess death rates, you need to analyze the raw data.

        • In order to understand how the authors came to their conclusions, you need to look at how they determined excess deaths.


          • They provide some of this in eTable 2.

          • They also list some of their results in the table provided in the 2023 paper, under the Figures/Tables tab. There, you see the breakdown of Excess Deaths in Florida and Ohio, broken down into the three time periods they used to assess the raw data: early covid, before open vaccine eligibility, and after open vaccine eligibility.


        • In comment 4, you now talk about "per capita death rates". You are not looking at "excess death rates", which is a standard method of assessment when trying to isolate one factor from many.

        • I stand by what I said in comment 3: It is quite possible that your interpretation of the "raw data" is using a biased pooling of the data that hides the relationship you don't want to see.


          • By looking only at raw death rates, regardless of cause, you fail to isolate the cause that creates excess deaths above the normal background rate.





    The "raw data" in eTable 1 does not show what you think it shows. It shows that more Democrats died in the 25-84 age classes from all causes. It does not provide a breakdown by time period (essential for evaluating the effects of different vaccine availability), and does not even mention the time period that the data covers (whereas other data in the paper tells us that they have broken the data down into different time periods).


    You close with "You will be surprised how often I am correct when you perform a basic level of due diligence. "



    • You have criticized Ecker et al for something  they did not say ("calls to stop misinformation". )

    • You have got the wrong version of Wallace et al when you referenced "raw data".

    • You picked a "raw data" table that does not assess excess death rates.


    Frankly, the level of "due diligence" that you have illustrated in your work is pretty poor. In comment 3, I closed by asking questions whether you were spreading misinformation. Now that I have further details on your level of "due diligence" and can see the data you are claiming supports your position, I can see that what you have said here does indeed represent misinformation.


    ...and yes - based on your history here - I would be very, very surprised to discover that you are "often correct". Nearly every time you comment, there are details you have left out that discredit your opinion.

  • Skeptical Science New Research for Week #1 2025

    Bob Loblaw at 11:13 AM on 7 January, 2025

    David-acct:


    Ah,yes, the cry of "censorship!". You beat that drum a lot. It was your opening statement when you commented a month ago, on the "Interview with John Cook about misinformation..." post. In that case, it was pointed out to you that the video said nothing at all about suppressing misinformation - just countering it. You doubled-down on your misrepresentation of that video. Whenever you open a comment with that cry, it only serves to reduce your credibility even further.


    I notice that you have not actually provided a link to the Wallace et al (2022) paper you are referring to. It is also not linked to in the quote that OPOF has included. Note that OPOF is quoting information from the first link in the OP. OPOF is not the one citing the Wallace paper - it is a cite in Ecker et al. For you to characterize it as OPOF's cite is misinformation.


    When I follow the cite in Ecker, I find the Wallace paper here. I do not see anything labelled "eTable 1". Searching the PDF, the word "table" doesn't even appear in the paper. There are several links to various data sources in their "Supplemental description of methods and data", but I can only hazard a guess as to whether this is the paper you are talking about, and what data table you think tells us what you say it does.


    When you say "...the raw data shows otherwise", you provide no data and no analysis of what you see in the "raw data". Data does not show anything. Data needs to be analyzed and interpreted. This is certainly true in science, and I suspect that even in accounting the "raw" data doesn't "show" anything until after someone looks at it and draws an interpretation from it.


    After all, the raw data for the entire US population shows that the average American has one testicle and one breast. Do you think that this would be a reasonable interpretation?


    FYI, in the abstract of Wallace et al, we get to see some of the interpretation that they applied to the "raw data" - interpretation that helps examine the question they have and avoid contamination from confounding variables:



    We estimate substantially higher excess death rates for registered Republicans when compared to registered Democrats, with almost all of the difference concentrated in the period after vaccines were widely available in our study states. Overall, the excess death rate for Republicans was 5.4 percentage points (pp), or 76%, higher than the  excess death rate for Democrats. Post- vaccines, the excess death  rate gap between Republicans and Democrats widened from 1.6 pp  (22% of the Democrat excess death rate) to 10.4 pp (153% of the Democrat excess death rate). The gap in excess death rates between  Republicans and Democrats is concentrated in counties with low vaccination rates and only materializes after vaccines became widely available.



    I also note that in their Results section, they talk about "relative excess deaths". This would be a type of analysis that would take raw death rates and try to account for other variables besides Covid. They say:



    This controls for differences in pre-COVID-19 death counts across calendar month, county of residence at time of voter registration, political party registration (Democrat or Republican), and age bins.



    So, you are (as you often do) just putting your own spin on something, and attempting to assert a conclusion without providing a justification. It is quite possible that your interpretation of the "raw data" is using a biased pooling of the data that hides the relationship you don't want to see.


    Have you done your own "due diligence" to analyze and interpret the "raw" data? Have you simply accepted the "findings" you read on some other web site about Wallace et al? Are you accepting some other person's opinion about Wallace et al because it fits your biased views?


    Are you spreading misinformation?

    David-acct at 10:04 AM on 7 January, 2025

    One planet - I agree that misinformation is a problem. However, calls to stop misinformation are essentially calls for censorship.



    A classic example is the Wallace et al study 2022 you cited which showed republican excess death rates were higher than democrat excess death rates. Republicans and Democrats—which is now associated with a widening gap in mortality rates (Wallace et al., 2022)—



    Fortunately, the study provided the raw data in eTable 1. Summary Statistics. The raw data devastates the study's conclusion. Did peer review even attempt to cross check the computation, or even do a simple math test?



    Per capita death rates for Democrats exceeded per capita death rates for republics in all categories in both states except for the 85+ age group in Ohio and Texas. How they could have possibly concluded republican excess death rates were higher than democrat excess deaths when the raw data shows otherwise.



    FWIW - I have seen this study posted several times on other websites, yet the advocates posting this study never seem to perform any level of due diligence and simply accept the findings because it fits their biased views. It simply is another example of misinformation.

    Sorry I didnt provide better example of the methodology errors in the pro masking studies.  I presumed everyone respondig would better understanding of the effect of cofounding variables.  The number one factor in the speed of transmission of a respiratory virus is time and space.  None of the pro masking studies demonstrated any effort to account for behavior changes that affected time and space, at least none of the 30-40 studies i evaluated.  Of furhter note, in all the pro masking  studies, the gap in infections rates all evaporated after 6-10 weeks and most of the time the unmasked population had lower infections rates after the 10 period.  


    The Kansas county mask v non mask county study was quite notable for the lower infection rates post study period.


    That is my primary point - The calls to suppress "misinformation" is a call for censorship as evidenced government efforts during covid.  


    Everyone loses in those cases


     


     


     


     

  • Interview with John Cook about misinformation and artificial intelligence

    Bob Loblaw at 02:32 AM on 9 December, 2024

    David-acct starts off his commentary with the one-liner, "Calls to suppress "misinformation" are in reality calls for censorship."


    I agree with what OPOF says at comment 8. I also watched the entire video. The video primarily uses the same word that appears in the text summary in the blog post: "counter". What does that mean? From Wiktionary: (to select the relevant definitions):



    Verb


    counter (third-person singular simple present counters, present participle countering, simple past and past participle countered)


    1) To contradict, oppose.


    Coordinate terms: counteract, counterargue, counterbalance, countervail


    ...


    3) To take action in response to; to respond.



    So, using "suppress" is a misdirection. It argues against a position that was not made in the text or video. As a counter-argument to David-acct's statement, I will say:



    Cries of "censorship!" are in reality attempts to silence counter-arguments. Typically, those that scream about censorshiip are the ones that want to suppress open discussion.



    The cry of censorship is sometimes framed as a "Free Speach!" cry. This usually amounts to a cry of "you aren't allowed to speak freely if you express disagreement, because I am supposed to be able to speak freely without opposition".


    [See how easy it is to use David-acct's tactics in the opposite direction?]


    Much of the rest of the video discusses how to recognize and counter various forms of misinformation. One of the points of discussion was how social media allows people to spread misinformation in short quips that appear convincing and appeal to emotion. Countering those bits of misinformation often requires lots of time, effort, and space as facts are presented.


    Guess what? David-acct is doing exactly that. Short, seemingly-convincing statements that discredit "virtually every pro masking study", and "vax efficiency". One-liners with no supporting references in an attempt to discredit the science. Exactly the kind of tactics that the video warns us about. And people have had to provide lengthy rebuttals, with links to more complete information, in an attempt to counter David-acct's misinformation.

    Calls to suppress "misinformation" are in reality calls for censorship.


     


    As evidenced during the Covid pandemic, almost all of what the experts and government authorities labeled "misinformation" turned out to be correct while much of the official authoritive pronouncements turned out to be false or highly misleading.

    Of course it is not anyone else's responsibility to help. I was hoping, however, that with this being a climate site, somebody here more knowledgeable in climate science than me would be anxious to help. This is how science progresses, and a true scientist would want issues and conflicts resolved as opposed to censoring the person who discovered it. But with the disrespect, unfair censoring, and just plain hostility shown me, I've obviously overestimated the "experts" at SkS and probably the entire AGW community.


    Textbooks have all the theory. Classes covering radiative transfer exist in many educational institutions. The LBLRTMs are physical models. The model predictions exist before the measurements to validate them take place. It takes a lot of painstaking work to build them but LOTRAN and MODTRAN are accessible to the public.

    Charlie Brown @ 757:


    Minor correction - yes, individual photons have the properties of both wavelength and frequency. Part of the weirdness of the particle/wave duality of light/EM radiation.


    The wavelength, frequency, and energy of a photon are all tied together. If it is a 15um photon, that also sets its frequency and energy level. All 15um photons are the same.


    A "stream" of photons is not like a stream of water where everything is connected. Even a stream of photons is just a bunch of individual photons passing one at a time past a point in space. When silicon diodes are used as radiation sensors, they are basically "photon counters".


    When a higher temperature means more energy emitted at a specific wavelength, it just means "more photons", not "more energy in each photon".

    I think it is useful to provide a graphic published in a 1967 paper by Manabe and Wetherald.



    Manabe, S., & Wetherald, R.T. (1967). Thermal equilibrium of the atmosphere with a given distribution of relative humidity. Journal of Atmospheric Sciences, 24



    Figure 16 looks like this:


    ManabeWetherald_fig16


    Note that increasing CO2 increases surface temperatures, but leads to cooling in the stratosphere. Why? Many factors, but one of them is that by adding CO2, the overall emissivity of the atmosphere increased - so the atmosphere can emit the same IR radiation to space at a lower temperature. Kirchoff's Law at work - both absorptivity and emissivity change in unison.


    But CallItAsItIs has not yet caught up with science from 1967, so he believes that only the emission of "thermal radiation" is being picked up by satellite sensors, and there is no emission from CO2.

  • CO2 effect is saturated

    Bob Loblaw at 00:25 AM on 26 November, 2024

    CallItAsItIs @ 740:


    Are you actually paying attention to what you are saying?



    • You have been claiming that there is no 15um IR radiation above your "extinction height" (10m) for CO2 to absorb.

    • I showed graphs (albeit modelled) with non-zero 15um radiation at altitudes from 10km to 70 km.

    • Now, you claim that the presence of that 15um IR radiation from 10km through 70km "tend[s] to show that I [you] am right", because "the detectors are only picking up some thermal radiation from the TOA".


    The level of physics denial is astounding. For your explanation to be correct, the entire atmosphere between the lower near-surface layers and the top of atmosphere layers cannot emit IR radiation in the 15um band. In your version of "physics":



    • There is lots of 15um IR radiation emitted upwards at the surface...

    • ...but a short distance above the surface, suddenly there is no upward emission of 15um radiation...

    • ...and there continues to be no upward emission of 15um radiation as we move higher and higher in the atmosphere....

    • ...until suddenly, at the top of the atmosphere, we suddenly find conditions that allow for the emission of 15um radiation so that the satellite sensors can pick it up.

    • ...and somehow "thermal radiation" is some different entity that does not exist in all those layers between the surface and the TOA. It only appears at the TOA, where you need it to "explain" what is measured from space.


    You are creating a physics-free zone between the surface and the TOA. In spite of the fact that the entire atmosphere has a temperature above 0K, and therefore contains thermal energy, and therefore emits thermal radiation (including 15um radiation, because the CO2 that is present can do that...), you have declared that none of that physics applies and none of the upwelling 15um radiation that is measured between the surface and the TOA exists.


    ...and then in comment 741, you wander off into a tangent claiming that my explanation in comment 732 requires that the atmosphere "heats itself" and "violate[s] energy conservation". That is more physics denial. Any object with a temperature >0K contains thermal energy. And the laws of physics state that any object >0K will emit radiation.


    When a molecule emits radiation, it loses energy (conservation of energy maintained) and will cool, but each molecule is capable of regaining energy by collisions with other molecules, or by absorbing radiation (in any wavelength - the absorption and emission do not need to be in the same wavelength).


    Remember in comment 722 when you said?:



    In the case of CO2 and the 15 micron absorption band, the N2 and O2 molecules in the surrounding air collide with energized CO2 molecules which causes the extra energy (from absorbed photons) to be converted into thermal energy, thereby raising the air temperature.



    The opposite is also true. CO2 can gain energy from N2 and O2 through collisions, when the N2 and O2 molecules are at higher thermal energy levels than the CO2. That is what predominantly drives the "thermal radiation" emitted by CO2 at all levels in the atmosphere. You can read the technical details in this post at Eli Rabett's blog.

  • CO2 effect is saturated

    CallItAsItIs at 04:56 AM on 25 November, 2024

    Bob Loblaw@724


    Above the extinction altitude of the 15 micron band, CO2 can still emit IR radiation (at any wavelength) but can no longer absorb within this band.  The fact that CO2 can no longer absorb within this band means that it has zero greenhouse forcing at this altitude and above for the simple reason that there is no more 15 micron radiation that can be absorbed.  The small amount of 15 micron energy that reaches orbital sensors comes from blackbody emissions from the top of the credible atmosphere.  This radiation cannot, however, be absorbed since there is no more atmosphere.

(The phalanx of co-authors are likely no more than window dressing and not contributors to the work. It is not impossible that a fair few of them had no knowledge of this co-authorship.)


    The main authors are "infamous" both for their climate denial and also their remarkable incompetence. They do however manage to string words together to create very lengthy papers, and in this case the offering comprised three lengthy papers (the other two here & here). As for the egregious error they have actually managed to incorporate into these particular offerings, that would take somebody to read through the drivel they present, no easy task when error is piled so high on error. Luckily, somebody has already done so, although for a detailed blow-by-blow rebuttal, there was a rebuttal of the rebuttal from Soon which was just as error-filled as the initial offering.

    Phillippe @ 26: "In fact, "the price" that people pay is exactly the reason why regulations and their strict enforcement are very much needed in this particular area,"


    I have spent time dealing with government procurement of meteorological sensors. For larger contracts, a bidding system is required. Many people complain about the complexity of the bidding process, but one of the main reasons for that complexity is because you need to be very careful about all the specifications.


    Why? Because  you know that there are vendors that will lie and cheat and steal and be dishonest about their product in order to win the bid. And once they have a contract, they know the government will have to pay them - because the product "met the specs" - even if it turns out that the product is a piece of $#!^,


    Same thing with regulations. If you say "that factory cannot release waste water containing more than 1g/L of arsenic", they'll just add more water to the arsenic mix until is "passes". You need to specify absolute amounts that can be released, regardless of dilution levels, if the river's ecosystem if affected by the total, not the dilution.


    When high levels of integrity exist, nobody needs lawyers.

    When you listen to businessmen in the private sector talk about their operations they speak revenue, productivity and efficiency, when you hear bureacrats they only talk head count and funding, no agency ever ceases to exist, it is assigned or assigns itself new missions and like all organizations seeks to grow and prosper as liberty withers and dies.

  • CO2 effect is saturated

    Bob Loblaw at 08:42 AM on 12 June, 2024

    Jim: I have not had time to read that paper in detail yet, but I can provide a bit of background.


    From the paper, it mentions



    AIRS is a grating spectrometer that measures spectral radiances in 2378 channels across the 2,169–2,673 cm−1, 1,217–1,613 cm−1, and 649–1,136 cm−1 bands and has calibration and stability performance since 2002.



    In order to get spectral data from a light source, the light source needs to be split into different wavelengths.



    • One way to do this is with optical filters - but you need one filter for each wavelength, so it is hard to get a lot of wavelengths this way.

    • The second method is to spread the light out by wavelength, like a prism does. You don't use prisms in such instruments though - you use either a narrow slit, or a diffraction grating. AIRS seems to use the latter.

    • Once the light is spread out, you need to measure it. One way is to have a single sensor move along the spectrum, but this is slow and mechanically complex (but highly accurate). The modern way is to put a diode array into the system, and each diode in the array falls at a different wavelength. That's what AIRS seems to use.


    The raw diode array output needs to get translated to spectral irradiance, and the spectral resolution is limited to the number of individual diodes in the array.


    The Raghuraman et al paper then increases the resolution using radiance models as an interpolation/enhancement method, and uses CERES broadband (not spectral) data to help limit the model results.


    In short, it's not a particularly simple process. Not surprising that it has taken time for someone to do it.

  • On Hens, Eggs, Temperature and CO2

    Bob Loblaw at 05:37 AM on 4 June, 2024

    RE: my comment 10:


    Now, if Koutsoyiannis et al want to claim that ENSO effects on temperature are irrelevant - i.e., that it does not matter if the temperature variation is due to ENSO, volcanoes, or fairy dust, etc. - then they can try to make that claim. But then they are breaking the chain of causality.


    Causation has to start somewhere, and their "unidirectional, potentially causal link with T as the cause..." is basically ignoring any previous cause. By ignoring anything else, they fail to consider the possibility that both T and CO2 are responding to something else (hello, ENSO!). And, of course, they ignore the possibility of feedbacks, where two or more factors affect each other - i.e., the world is not unidirectional.

  • On Hens, Eggs, Temperature and CO2

    Bob Loblaw at 04:24 AM on 4 June, 2024

    As MAR points out in comment 9,  Koutsoyiannis et al ignore ENSO as a possible factor in their analysis.


    Is ENSO a factor in global temperatures? Yes. Tamino has had several blog posts on the matter, where he has covered the results of a paper he co-authored in 2011, with updates. The original paper (Foster and Rahmstorf, 2011) looked at the evolution of temperatures from 1979-2010, and determined that much of the short-term variation is explained by ENSO and volcanic activity. After accounting for ENSO and volcanic activity, a much clearer warming signal is evident.


    Tamino recently updated this analysis, with modified methodology and covering a longer time span (1950-2023). This method turns this:


    Tamino raw


    to this:


    Tamino adjusted


     


    Now remember: Koutsoyiannis et al used differenced/detrended data in their analysis, which means that they have removed any long-term trend and fitted their analysis to short-term variations. If you remove the short-term effects due to ENSO, Koutsoyiannis et al will have a temperature signal with a lot less variation. That means they have a lot less ΔT to "cause" CO2 changes. Their physics-free "causality" gets stretched even thinner (if this is possible with an analysis that is already broken).

  • On Hens, Eggs, Temperature and CO2

    MA Rodger at 01:41 AM on 4 June, 2024

    The most powerful message of the paper Koutsoyiannis et al (2023) 'On Hens, Eggs, Temperatures and CO2: Causal Links in Earth’s Atmosphere' is their "Graphical Abstract" which is reproduced in the OP above as Figure 1.


    They are not the first to try and use these data to suggest increasing CO2 is not warming the planet. And likely there will be other fools who attempt the same in the future.


    So what does their "Graphical Abstract" show?


    The graphic below is Fig2 of Humlum et al (2012) which insists this same data shows that CO2 lags temperature and not the other way round.


    Humlum et al 2012 fig 2


    The data that is missing is the ENSO cycle which precedes both  the T and the CO2 wobbles and thus drives global temperature wobbles and, by shifting rainfall patterns, drives CO2 wobbles. To suggest (as Koutsoyiannis et al do) that such "analyses suggests a unidirectional, potentially causal link with T as the cause and [CO2] as the effect" is simply childish nonsense.

  • Shakun et al. Clarify the CO2-Temperature Lag

    Paul Pukite at 23:02 PM on 6 May, 2024

    Lags are tricky in feedback-controlled systems. If one signal is 90 degrees out of phase with another, you can't really say one is leading or lagging over the other.


    However, it's clear for the current interannual measure that CO2 lags the temperature shifts as T is clearly primarily seasonal and secondarily ENSO+AMO related. CO2 simply follows that temperature change via the outgassing relationship.


    More problematic IMO is the belief that ENSO is a lagging indicator to shifts in prevailing winds, i.e. shifts in prevailing winds will trigger an El Nino event. One can argue that the winds are in fact a lagging indicator of the ENSO phase, with climatologists not able to accurately discriminate the two signals precisely enough. AFAIK there is only one article that has looked closely at this  https://www.nature.com/articles/s41598-019-49678-w and they find that ENSO is initiated at the subsurface level (likely due to tidal cycles).  The wind is a lagging indicator as the ENSO modified thermocline level creates spatially-resolved surface temperature  variations, leading to atmospheric pressure gradients, and that's what drives the wind as it blows from regions of high pressure to low pressure. This happens dynamically so it explains why so many are fooled by this misguided correlation = causation attribution.

    Two Dog, I don't want to be dog-piling, but I am very curious as to how you assess evidence when you are examining a question like global warming? We are seeing the same information, and yet to my mind you are fixating on the very unlikely or what you seem to think is unknownable rather than the obvious, the observable and the extremely likely. Other commentors have commented on your tendency to push what they see as straw-man arguments - you seem to be confident the scientists say things or work in ways that they dont. I am curious as to what informed assertions like these?


    Can I assume that you comfortable with conservation of energy? So that any change in temperature involves moving or transforming energy. Consider total ocean heat content - a much less noisy measure than surface temperature and the ocean is where most of the heat is going.

    Ocean heat content


    The blips you see here in the red on this record are the near-surface action of ENSO - when the upwelling of warm water to surface heats the atmosphere but cools the ocean.

    Do you agree that all that heat has to come from somewhere whether it is natural or anthrogenic? If your priors are to assume it is natural, then how do you start to think about what might be causing it and what measurements would you like to  make to verify or falsify?


    Also, you do realise that increased radiation from the CO2 has been directly measured? In terms of likelihood, the match between the  amount of excess radiation and increased ocean heat content would be strong evidence for anthropegic warming for most people. I am assuming your priors would try to discount that so again, what do you think happens to excess radiation from the greenhouse effect and what kind of measurements would you use to verify?

    "You make the same point I am searching for - namely that "blips" in the temperature record can be driven by natural factors. What puzzles me is others on this thread, whilst they recognize these natural impacts, appear confident that the natural factors that we are aware of are "temporal and not significant" (my words) when pitted against the powerful impact of human GHG emissions"


    Nobody has claimed natural factors are all 'insignificant' forcings. Only that the natural cycles are in a cooling or flat phase in recent decades so cannot explain the recent warming trend. However the solar cycle is not a particularly powerful factor,  and if it was in a warming phase it would struggle to explain more than a small amount of the recent warming. Refer to the climate myth "It's the sun" on the left hand side of this page.


    "They rely on climate scientists for this - a group who are highly unlikely to admit the strength and frequency of natural factors is unpredicatble and hard to measure."


    Incorrect. Climate scientists freely admit that the frequency of natural factors can be unpredictable to an extent. I provided you with data on the solar cycle, ENSO, and The PDO oscillation which depicts the degree of regularity of these cycles. You can see there is a repeating cycle bit its not perfectly regular.This data is prepared by climate scientists.


    In addition whether they are not precisely predictable doesnt stop us detecting how they are affecting temperatures at any given time.


    Climate scientists are quite open about accuracy of data. If you dig into the details the data has error bars. However the data has generally good accuracy. Solar irradiance in particular is meaured by satellite sensors with reasonable accuracy, and the Sorce network used since 2003 is highly accurate:


    www.ngdc.noaa.gov/stp/solar/solarirrad.html


    ENSO index is not that hard to measure with decent accuracy:

    "I think this is where the climate scientists tend to differ from the physicists and geologists, whose very existance does not require them to claim knowledge of all factors that impact the climate."


    Incorrect. Most climate scientists are in fact physicists, geologists, chemistry graduates etc. There is a degree in climatology, but its very recent and not many climate scientists have that degree. It typically has modules in physics and geology anyway. I suggest google it for your local university.

    The greening of the Earth is approaching its limit.


    When plants absorb this gas to grow, they remove it from the atmosphere and it is sequestered in their branches, trunk or roots. An article published today in Science shows that this fertilizing effect of CO2 is decreasing worldwide, according to the text co-directed by Professor Josep Peñuelas of the CSIC at CREAF and Professor Yongguan Zhang of the University of Nanjin, with the participation of CREAF researchers Jordi Sardans and Marcos Fernández. The study, carried out by an international team, concludes that the reduction has reached 50% progressively since 1982 due basically to two key factors: the availability of water and nutrients.


    "There is no mystery about the formula, plants need CO2, water and nutrients in order to grow. However much the CO2 increases, if the nutrients and water do not increase in parallel, the plants will not be able to take advantage of the increase in this gas", explains Professor Josep Peñuelas. In fact, three years ago Prof. Peñuelas already warned in an article in Nature Ecology and Evolution that the fertilizing effect of CO2 would not last forever, that plants cannot grow indefinitely, because there are other factors that limit them.


    If the fertilizing capacity of CO2 decreases, there will be strong consequences on the carbon cycle and therefore on the climate. Forests have received a veritable CO2 bonus for decades, which has allowed them to sequester tons of carbon dioxide that enabled them to do more photosynthesis and grow more. In fact, this increased sequestration has managed to reduce the CO2 accumulated in the air, but now it is over. "These unprecedented results indicate that the absorption of carbon by vegetation is beginning to become saturated. This has very important climate implications that must be taken into account in possible climate change mitigation strategies and policies at the global level. Nature's capacity to sequester carbon is decreasing and with it society's dependence on future strategies to curb greenhouse gas emissions is increasing," warns Josep Peñuelas.


    The study published in Science has been carried out using satellite, atmospheric, ecosystem and modeling information. It highlights the use of sensors that use near-infrared and fluorescence and are thus capable of measuring vegetation growth activity.

    So far it appears that there are simultaneous spikes in the temperature of 3 different ocean indices ENSO (Pacific), AMO (Atlantic), IOD (Indian). The last time that happened was in 1878, the year known for a super El Nino. Can see the 2 spikes in AMO for 1878 and 2023 in the following chart.

    Dessler's post does rather hedge its bets by suggesting it might be "due to natural variability persisting over an extended period" which will at some point come to an end (so as per the 2007-12 slowdown but in reverse). But he also points to the recent deep La Niña which may be amplifying the impact of the less-than-massive El Niño.


    The ENSO indices do show the build-up to present weak El Niño conditions were unusually preceded by strong La Niña cinditions which had been, if anything, strengthening through the period rather than, as is usual, weakening as El Niño conditions approach. (The MEI perhaps shows this situation best.) Yet the big 1997-98 El Niño also strengthened quite suddenly and showed nothing like this 2023 bananas situation.


    MEI el nino profiles


    The bananas (sudden appearance of an additional +0.2ºC in the global average temperatures) won't be some sudden forcing as there is no sign of anything (or things) approaching the required force. That means we have a natural wobble.


    But is that wobble reversing something that has been shielding the impacts of AGW and so it won't reverse? Or is going to abate in coming months/years? Dessler looks to the climate models as suggesting it is the latter. But the question is still an open one!!

    Regarding the discussion of ENSO patterns, modelling and forecasting.


    The SkS Argument/Myth item "Global warming and the El Niño Southern Oscillation" that John Mason @31 suggested as a more appropriate thread has some potentially very relevant points made in the latest comments starting with comment 198 (from 2019).


    Another location of potentially helpful information is the Australian Bureau of Meteorology's "Climate Driver Update" website (linked here). The "Pacific Ocean" tab (linked here) presents a broad range of forecasts for the NINO3.4 SST from multiple forecasters. There is approximately a 1.0 degrees C range of forecasts for January 2024.

    So a monograph that I cannot access and a paper with 21 citations.  Not very impressive.  How well did the group that published the paper predict in advance the last 5 years of La Ninas and the current El Nino?  I am always skeptical of claims that tidal forces can cause changes in weather a year later.  


    It appears to me that the general description that ENSO is random and not predictable in advance is correct.  Your claims at post 34 do not hold up to close inspection.  You are welcome to believe anything you like.

    "I note that your post at 34 contains several completely unsupported assertions."





    No problem. Concerning the points that ENSO is not chaotic, not random, and not driven by wind, there are a couple of citations I can point to. The most comprehensive is a monograph that I co-authored titled Mathematical Geoenergy  (Wiley/AGU, 2018, chapter 12: Wave Energy) . Another coincidental finding was reported Lin & Qian "Switch Between El Nino and La Nina is Caused by Subsurface Ocean Waves Likely Driven by Lunar Tidal Forcing"  https://www.nature.com/articles/s41598-019-49678-w


    These of course havee nothing to do with climate change, as according to the definitions at this site, ENSO is apparently not considered climate change, but as climate variability.

    The graphic uses the GISS temperature data, color-coded by ENSO phase, updated through the end of 2021. When the full-year data for 2023 comes out, it should get updated then. The slopes will change somewhat as the background phase states change, but the underlying exogenous driver is still human activities.  As a result, ocean heat content rates are accelerating (from Li et al 2023, Figure 1), further warming all ENSO phases over time:

    Yes, this is getting off-topic.  Risking pushing the envelope, all ENSO phases are clearly warming, due to the underlying and overburdening human forcing of climate becoming increasingly pervasive.  Perhaps a better thread can be suggested for such (but not here).

    But you asked why I commented on this post with respect to ENSO, when it was you that mentioned La Nina in the the post itself.  But we're no longer in a La Nina regime but in El Nino.


    I just wanted to test the waters here again to see if this site has changed its approach to being more about research than gatekeeping. I keep thinking that the name Skeptical Science describes the charter.           


    I am skeptical that ENSO is chaotic.
    I am skeptical that ENSO is random.
    I am skeptical that ENSO is triggered by a change in prevailing winds. 


    I think I get it — the skepticism is directed not at current models of bleeding edge climate science where millions of $$ are being poured into machine learning for ENSO predictions by the likes of Google and NVIDIA, but at skepticism to combat crackpot models that claim AGW is being generated by subsurface volcanic activity.

    "Sea-surface temperature patterns in the tropical Pacific were characteristic of La Niña, a phenomenon that should have mitigated against atmospheric heat gain at the global scale. However, the annual global surface temperature across land and oceans was among the six highest in records dating as far back as the mid-1800s. 2022 was the warmest La Niña year on record.


    At the time of writing, there is still about a month of 2023 to run. Yet once again we have record-breaking temperatures, with some records smashed by huge margins, so that 2023 looks as though it may well go down as the hottest on record."

    There was a long-running discussion on ENSO at the Azimuth Project forum started in 2014 that recently ended.  The original motivation was  to collaborate and analyze ENSO data and consider different math approaches to modeling the cycles, as the organizers of the project were skeptical as to a chaotic or random origin for ENSO. Alas, the owner of the site shut it down and wiped out the entire archive.  Fortunately, some of the open source code for the effort was kept on a GitHub repo and I was able to grab ownership and keep that alive, so a remnant discussion is available for those that have GitHub accounts.  https://github.com/azimuth-project

    Paul Pukite,


    I like John Mason’s question @26. But would extend it as follows: “...why did you choose to interject on this thread...” the way that you did @2?


    Though you have not directly addressed the questions I raised @4 regarding your comment @2, your latest comments appear to indicate an awareness that it was incorrect to state that there was no similar warming in “the middle of the equatorial Pacific” [quote from you @2] (I agreed that it is worthy of being thrown away). But I still do not see indications of awareness that it was also wrong to try to justify that incorrect assertion by misrepresenting the paper you linked @2 with a ‘quote-clearly-out-of-context’.


    Making incorrect statements with questionable or made-up justifications and then arguing against attempts at clarification and correction of the incorrect belief is similar to the behaviour of the regular denizens of sites like WUWT and Dr. Roy Spencer.


    I wish you luck in your endeavours to ‘constantly learn more about ENSO – constantly changing your mind as you learn more’.

    Paul Pukite,


    At post two you said "Not the middle of the equatorial Pacific." Referring to  the comment "All these show a similar warming trend." 


    At post 7 you said "when one searches for equatorial Pacific ocean SST time-series, you only get NINO34, NINO4, etc data. These show no or very little trend,"


    I entered the thread to show that your comments were false.  My illustration at post 9 clearly demonstrates that you were incorrect.  You posted a graph at post 13 claiming no trend, asserting that the graph had not been detrended.  My post at 21 showed your graph was detrended and your claims of no trend in the tropical ocean are simply false.


    Now at 23 you post a graph that is actually not detrended and use your eyecrometer to claim your graph is more informative than my illustration.  Using my eyecroneter on my illustration I see clearly that the trend is closer to one degree.  If you put a least squares line on your graph we would have data instead of idle speculation. All these trends can easily be Googled, you are simply not looking.


    I have proved beyond doubt that your claim that the tropical oceans "show no or very little trend," is completely false.  The fact that you produced a graph that was not detrended and showed a trend after claiming a detrended graph showed there was no trend indicates that you are not interested in a discussion of the science here. 


    If you want to speculate on ENSO causes go for it  As I understand it, ENSO is essentially random on a yearly basis.

    Paul Pukite at 16:27 PM on 3 December, 2023

    I don't think you have any idea what my objective is.  I frankly don't worry about modeling AGW as that's in good hands, IMHO.  Instead, what I have been trying to do the last several years is model natural climate variations such as ENSO, AMO, PDO, etc.  You may find it odd, but not observing a large contribution of an AGW signal in a time-series such as NINO34 actually makes it easier to do the modeling since the signal vs noise discrimination is more apparent. In other words, the underlying trend is so small relatively speaking that it doesn't matter if the time-series is detrended or not when fitting a model to the data.


    So based on my actual research interests, I would much rather discuss ideas concerning forcing factors behind ENSO — including tidal & annual — than deconstructing my phrasing in a tossed-off comment. If you want to delve into modeling of the geophysical fluid dynamics and how neural nets and machine learning may be helping in revealing patterns instead of pedantic point-scoring, I am game.  I will grant you a win on all the petty stuff as you seem so determined to play gotcha on a comment I made based on dealing with the data for years now.

  • At a glance - Evidence for global warming

    One Planet Only Forever at 14:11 PM on 3 December, 2023

    Paul Pukite @23,


    I will continue to pursue the points I raised regarding your comment @2.


    I am confident that nigelj’s comment about similar trends was regarding ‘a trend like the global average surface temperature data - warming rather than cooling with more significant warming occurring after 1950 than prior to 1950’.


    Your comment @2, and later comments except for your latest @23 (sort of), appear to insist that it is not possible to have confidence regarding a warming trend in the NINO 3.4 region (the middle of the equatorial Pacific).


    Your comment @2 starts with:


    "All these show a similar warming trend." [nigelj’s point]
    Not the middle of the equatorial Pacific. (your response)


    As my comments should indicate, I learned from and accepted nigelj’s finding of an explanation about the current models indicating a larger amount of warming in the equatorial Pacific (especially the east part) than the actual observations. However, as I commented, that does not alter the incorrectness of your comment @2. But you do appear to have finally accepted your incorrectness (sort of) by ‘seeing’ a warming trend in the NINO 3.4 SST data.


    However, I am still confident that it is incorrect to declare that having confidence that ‘the NINO 3.4 SST historical data indicates warming similar to the global average surface temperature data’ requires an accurate explanation for the trend being lower than the current global climate models for that region and it requires that understood influence to be removed from the SST values.


    The data is what it is regardless of the mechanisms producing it. Large variations of the temperature data simply requires a longer duration of the data set to have confidence that there is a warming trend. And a lower trend rate will also require a longer data set to establish confidence.


    The NOAA presentation of the centered 30-year base periods (linked here) that I provided a link to in my comment @16 helpfully presents the trend of the SST NINO3.4 data set in spite of significant variations in the data values. Each 30-year period contains a substantial variety of the variation. Comparing the 5 year steps for the data starting in 1936 shows that there is indeed a recent trend (more significant after 1950 than before 1950 – consistent with the NINO3.4 chart you included in your comment @23). The 1966 to 1995 values, and all the more recent ones, are clearly warmer than the earlier ones. However, it also shows that the ENSO perturbations in the data are large enough to make the warming trend hard to be confident of, even appearing to potentially be a cooling trend in a shorter data set. The 1981 to 2010 results are not clearly warmer, and may even be cooler, than 1976 to 2005.


    Global average surface temperature data evaluations using the SkS Temperature Trend Calculator (linked here) can also provide an example supporting my confidence that the ‘noise’ of ENSO variations do not need to be removed to be able to have confidence regarding a trend.


    As I indicated in my comment @17, using the GISTEMPv4 dataset in the SkS Temperature Trend Calculator (linked here) the trend of the data after 1950 is 0.152+-0.018 C / decade (high confidence of a warming trend). I add the following set of shorter recent time periods and the resulting trend and level of confidence (2 sigma value compared to trend value):


    Years                  Trend +- 2 sigma
    2016 to 2023 = -0.148 +- 0.513
    2015 to 2023 = -0.066 +- 0.428
    2014 to 2023 = +0.074 +- 0.379
    2013 to 2023 = +0.180 +- 0.331
    2012 to 2023 = +0.244 +- 0.289
    2011 to 2023 = +0.284 +- 0.249
    2010 to 2023 = +0.262 +- 0.220
    2005 to 2023 = +0.229 +- 0.129


    The longer the time period is the more confidence there is in the evaluated trend. Admittedly the global average surface temperature variation in the evaluations is only about 2 degrees C. So a longer time period would be expected to be required for the NINO SST values because they have larger variation of temperature and a smaller trend. But confidence regarding the trend can still be established without a detailed understanding of the mechanisms at play. And I am confident that the authors of 2012 report you (mis)quoted in your comment @2 had reason to be confident with their evaluation and reporting (repeating part of the quote I had included in my comment @4)


    “...While centennial trends are not assessed here, we note that using a reduced period results in more consistent linear trends in SSTs over the 61-year record (Fig. 1), which are significantly positive throughout the tropical Pacific Ocean.”


    What the authors of the paper observed and explained, was that the pre-1950 data was not as reliable as the post-1950 data. And since the main interest is ‘warming similar’ to the global average surface temperature which has more significant warming since 1950 than before 1950, the earlier SST values are not that important.

    It's interesting to compare NINO34 almost-raw (annual cycle is still removed) and de-trended 


    This is raw from KNMI explorer site


    https://climexp.knmi.nl/getindices.cgi?WMO=NCDCData/ersst_nino3.4a&STATION=NINO3.4&TYPE=i&id=someone@somewhere


     


    This is de-trended


    https://climexp.knmi.nl/getindices.cgi?WMO=NCDCData/ersst_nino3.4a_rel&STATION=NINO3.4_rel&TYPE=i&id=someone@somewhere


    So there appears to be a ~0.5 degree trend removed over the time span.  All my original comments stated were that the trend was difficult to discern because of the dominating ENSO variations and those are not understood very well.  That's all I said, go back and check.


    In terms of optimal control theory, properly removing the signal (a warming trend) from the noise (ENSO variations) is only possible if a model for the noise is known. If the noise is statistically random with no trend, it's practical to create e.g. a Kalman filter to optimally remove  the noise.  However, if the noise of ENSO carries long-period multidecadal fluctuations, such as is observed with the AMO on the Atlantic side or the decadal PDO in the north Pacific, then it becomes much more challenging to discriminate the noise from the signal. That's because climate scientists still have no validated model for ENSO, being unable to predict it more than a few years in advance.   


    The ~1/2 degree warming in the NINO34 time-series above is in all likelihood a real AGW effect but my original remark was only in pointing out that the comment by Nigel J: "All these show a similar warming trend" could be challenged.  He was OK with my remark as he found the case of the Pacific cold tongue research, which is described by NINO12 (and even more diffficult to extract the trend) and that the map by MS doesn't show this at the granularity needed.  So are the rest of you speaking for him?

    Paul Pukte @10,


    When you present a graph and say "my eyecrometer detects no trend" with no statistical analysis you are wasting our time.   Likewise when you say "I am pretty certain this is not detrended" you are wasting our time.  If you are not absolutely certain the data is not detrended go find out for sure.


    When I go to your data source I find the graph you have presented has this label:


    "cutting out region defined by mask ersstv5 nino3 mask.nc, operating on NOAA ERSSTv5 (in situ only), SSTA normalized to 1981-2010, Nino3 index minus 20S-20N average SST, normalised by a factor" my emphasis


    It appears to me that your graph shows the anomaly in the Nino3 area  minus the trend in the tropical oceans.  Since the illustration that I posted in post at 9 shows that the tropical ocean has a clear waring trend.  You have ignored since it contradicts your claims.  It appears to me that your graph shows that the ENSO anomally has not changed compared to the rest of the ocean, not that the temperature has not risen in the Nino 3 area as you claim.


    I note the the older data in your graph must have large error bars.  I also note that small areas of the globe have much more noise so it is hard to detect the warming signal, especially by eyecrometer.

    There could be a warming trend buried in the NINO3 time-series but it's difficult to extract because of the large El Nino and La Nina excursions — note that they exceed 4C on the positive side and almost that much on the negative side. Remember that this region is the source of energy (or sink of energy) which can heat up (or cool down) the world for months at a time so it may be understandable that the AGW trend gets buried.


    https://climexp.knmi.nl/getindices.cgi?WMO=UKMOData/hadisst1_nino3a&STATION=NINO3&TYPE=i 


    It's difficult to do statistical trend analysis on such a time-series without a model of the underlying "nuisance" signal. Since I have been doing mainly ENSO research, having published and presented at several AGU/EGU meetings on the topic, I tend to think of the AGW as the nuisance — tho, since it's so small it's not much a nuisance.  On the other hand if you're iterested in the AGW trend here, the ENSO signal is a huge nuisance.

    Paul Pukite @13,
    Your latest comment does not address the questions I raised regarding your initial comment and the ways you have commented regarding this point.
    @2 You said “...Not the middle of the equatorial Pacific. The temperature variation there is also not well understood because El Nino & La Nina cycles dominate and these are difficult to predict more than a year in advance.”


    I am open to learning (even though I still struggle with right vs left hand). Years ago I learned that the difficulty in ‘predicting the ENSO’ does not affect the ability to evaluate trends in the equatorial Pacific SST. Due to the trend of SST in the Niño 3.4 region (the middle of the equatorial Pacific) NOAA had revised their methodology for the Ocean Nino Index (ONI) values to be relative to a regularly updated baseline.


    The following is from the NOAA webpage (linked here) that presents the ONI values identifying the “Cold & Warm Episodes by Season”.


    “DESCRIPTION: Warm (red) and cold (blue) periods based on a threshold of +/- 0.5oC for the Oceanic Niño Index (ONI) [3 month running mean of ERSST.v5 SST anomalies in the Niño 3.4 region (5oN-5oS, 120o-170oW)], based on .”centered 30-year base periods updated every 5 years.”\


    And the linked NOAA webpage for “centered 30-year base periods updated every 5 years” shows the annual temperature curves for each of the 30-year base periods. In that presentation there is an undeniable warming trend since 1950.


    What you will notice is that the NOAA ONI and the related base periods start in 1950. This ties directly to the paper you made the unrepresentative quote from mistakenly believing that it supported your incorrect ‘declared belief’ about the middle of the equatorial Pacific.


    In closing I will say that a statistical evaluation of the data points is the proper way to determine a trend in the data. However, when I look at the NINO3 graph you have chosen to share I see a warming trend for the portion from 1950 to 2010. That would be consistent with the more valid evaluation of the data done by the authors of the paper you misrepresented in your comment @2.

    Paul Pukite at 01:16 AM on 1 December, 2023


    one has to look fairly hard for maritime areas that do not show a "similar warming trend"



    As far as I can tell, when one searches for equatorial Pacific ocean SST time-series, you only get NINO34, NINO4, etc data. These show no or very little trend, being dominated by ENSO variations.  As far as I can tell, they have not been detrended, but do have the annual seasonal temperature cycle removed. 


    Proxy records to demonstrate the hockey stick contain many samples from coral ring measurements.  Yet, these also show very little trend which is not surprising as most coral is found in tropical or equatorial waters, where the SST also shows little trend.  That's why most hockey stick discussion is on tree ring data.

    nigelj at 10:59 AM on 28 November, 2023

    Regarding David Acct's comments where he says some of the authorities did exaggerate the effectiveness of the masks. I agree that was the wrong thing to do, but I'm prepared to be a bit forgiving as they were simply trying to encourage use of maks to save lives, and remember we were in a quickly evolving emergency situation with some uncertainty about how effective masks were. We are now looking back with the benefit of hindsight. I agree with Bob it was not misinformation.


    David seem to be narrowly focused around whether face masks stop people catching covid. Obviously masks won't do much to stop you getting infected because they dont fit tightly enough and it only takes a very small number of cells to cause an infection. The studies seem to show that areas with high mask use had only slightly lower rates of infection. About what you would expect.


    But masks do greatly reduce the viral load on the lungs and that initial viral load is closely related to severerity of symptoms. Its no accident that places with high mask use had a much lower mortality rate (25% in one study). So on balance it appears to me mask wearing does have value.


    David does a rant about the virtues of free speech and the evils of censorship. I lean towards free speech, but I would boldly say that some censorship is required in some circumstances. It's common in times of war,and in New Zealand we have sensible laws against defamation, inciting violence and racist speech (which effectively incites violence) and as a result many websites will not publish public comments that infringe those laws. That is censorship, so lets call it what it is, but only a fool would suggest such laws and censorship is wrong.


    But how much further should we go? Because every restriction on free speech does risk shutting down discussion and debate, which is a very unhealthy outcome. I believe restrictions and "censorship" should be small in number and only be if there is a risk of comments inciting criminal law breaking or leading to serious physical harm or in other exceptional circumstances.


    For example during covid our media mostly allowed people to post comments on their websites with robust views or even crazy views on covid, but they generally wouldn't permit views undermining the use of vaccines, such as views making wild claims that vaccines dont work or that they kill people.


    This seemed like a reasonable restriction because it was narrowly focused and related to potential loss of life. The country was actively trying to get vaccination rates as high as possible and we got to 95% double vaccinated. America land of free speech only got to about 65%. A lot of people died but they preserved their precious right to spread lies about vaccines. I find this approach rather bewildering and lacking in commonsense.


    On the other hand, attempts to censor so called 'hateful' views and criticism of religion mostly seem to go too far and run into awful difficulties of defining what hate speech is.


    Yes all of this means free speech is not a simple black and white thing and difficult judgement calls have to be made. I think we are just stuck with this and have to do the best we can.

    One Planet Only Forever at 07:27 AM on 28 November, 2023

    David-acct @4 (Note: I prepared this before seeing Bob Loblaw’s recent post)


    I agree with BaerbelW @5. And I agree with you, sort of (see my ending PS).


    Censorship, like ‘efforts to ban school books because they would increase awareness and improve understanding of how to be less harmful and more helpful to Others’, is indeed unacceptable. It is especially unacceptable to ‘censor education’ to only teach ‘reading-writing-math’ and ‘incorrect but preferred versions of history’.


    However, a rational justification can be made for improving public education, a requirement for democracy to be sustainable, by limiting the success of authoritarian attempts to popularize inaccurate information. Those limiting actions are justified even if fans of the misunderstandings, people who idolize undeserving authority figures, claim that such corrective actions are ‘censorship’ or ‘evil re-education’.


    An example in schools would be moving texts that incorrectly portray the history of what has occurred into a ‘special section’ where the inaccuracies are explained in detail for anyone interested in learning about that (regardless of the preferred beliefs of ‘winners of elections’).


    In addition, being addicted to the pursuit and promotion of harmful misunderstanding is understandable, especially when the addiction is to unjustified perceptions of status relative to Others. However, an addiction to the pursuit of increased awareness and improved understanding of what is harmful and required corrections of unjustified developments and perceptions of success and status is also understandable.


    Something like Addiction (or censorship) is not the problem. The problem is opposition to, rather than support for, ‘learning to be less harmful’. The same applies to political positions. Positions on the Left-Right spectrum are not ‘the problem’. The problem is ‘arguing and fighting against the pursuit of increased awareness and improved understanding of what is harmful and the diversity of justified corrective actions’. The corrective actions include actions that would limit the success of misinformation and disinformation efforts.


    Misleading claims about ‘censorship’ are understandably expected from easily impressed victims or wilful perpetrators of misleading disinformation campaigns in the ‘War on increased awareness and improved understanding of undeserved perceptions of superiority and status’.


    Ibram X. Kendi, in his many well researched books, provides a very robust understanding about the continued ‘progress of racist actions to defend unjustified perceptions of superiority relative to Others’. The reality that climate science also challenges unjustified perceptions of superiority makes it another front in the war efforts of people opposed to learning to be less harmful and more helpful to Others.


    There are many valid justifications for restrictions on freedom. Helpful, justified, educational actions, including restrictions, are not censorship. Limiting the ability to spread harmful misunderstandings is not censorship. Arguing for the unrestricted sharing of misinformation would be like arguing for no efforts to limit the popularity of any of the many misleading harmful ‘social media popular challenges’ (share a video of biting a laundry-pod).


    Limiting and correcting the popularity of harmful misunderstandings, especially with actions like educational inoculation, is not censorship. It would be more accurate to call such actions ‘Helpful Public Education’.


    PS. Regarding the spread of a disease like COVID-19, I would agree that limiting-restricting contact between people is more effective than ‘mask wearing’ (and the type of mask also matters).

  • Disinformation campaigns are undermining democracy. Here’s how we can fight back

    Bob Loblaw at 05:26 AM on 28 November, 2023

    I see that David-acct has returned to inject another (likely one-off) comment on a  thread, in an attempt to discredit the science. This time, he is yelling "censorship", in spite of the fact that the blog post does not advocate for the "suppression" he claims is a "far greater threat to democracy".


    The blog post does refer to EU efforts "to make democracies more resilient against misinformation and disinformation", and about efforts "to boost the public’s resistance to misinformation". The paper on which the blog post is based gives more details: mentioning EU Codes of Practice and legislation attempting to "curtail misinformation and hate speech online". It also mentions the use of moderation policies "to remove online misinformation and hate speech under certain circumstances". In other words, "free speech" has limits.


    In David-acct's world, it seems that helping people recognize and resist misinformation is "censorship". It would seem that David-acct's desired world is one where nobody is allowed to speak against misinformation. To me, there seems to be a pattern in many of these discussions - the "advocates' screaming about free speech and censorship seem to only approve of "free speech" by people they agree with. They appear to want "my free speech, unopposed". "Free speech" is not limited when people speak against you, and "free speech" does not mean that every online discussion group must provide you with a bull-horn. When someone violates a code of conduct on a commercially-run discussion group, and is barred from further participation, it is not "censorship". They are always free to set up their own web site and discussion network.


    [Disclaimer: Skeptical Science has its own code of conduct for participants, known as the Comments Policy.]


    David-acct then wanders into a Covid discussion, and finishes with an unsubstantiated claim that "the health authorities pushed as much or more covid disinformation than the denialists." He provides a link to a paper that he claims is "a good article on the effectiveness of masking". If we actually read the paper, what we find is an article that includes things like the following, where they discuss possible bias in their study:



    The participants in the study were not randomly assigned to wear or not wear face masks, and they were not provided with or encouraged to use face masks. During the study period, official guidelines for face mask use changed, with mandatory use in certain situations. This may have affected the participants' use of face masks, with some choosing to wear them based on their own assessment of risk and effectiveness.


    Additionally, there may be other factors that could confound the relationship between face mask use and study outcomes, such as participants in high-risk professions or with risk factors for severe COVID-19. Both groups may be more or less prone to wear face masks, while also observing different social distancing practices than the average population. We also cannot rule reverse causality, in which those testing positive for COVID-19 were more prone to wear masks afterwards in order to protect others. Finally, there could be an association between the inclination to test and the propensity to wear a face mask.



    They conclude that section with the following statement:



    However, it is important to interpret the results with caution and not infer that our estimates represent the true causal relationship between face mask use and infection risk.



    So, the "good article" David-acct wants us to read is hardly the definitive source that David-acct is pretending it is. What David-acct has done is cherry-pick one study, and present it as far more conclusive than it is. If he had read even just the abstract, it finished with a general cautionary note (applicable to all studies):



    We believe the observed increased incidence of infection associated with wearing a face mask is likely due to unobservable and hence nonadjustable differences between those wearing and not wearing a mask. Observational studies reporting on the relationship between face mask use and risk of respiratory infections should be interpreted cautiously, and more randomized trials are needed.



    Also note that the paper David-acct refers to is a pre-print of an accepted paper, published online on November 13, 2023. Can anyone think of a possible reason why a study published in late 2023 was not used to guide policy decisions in early 2020? Does David-acct think that the 2020 policy decisions should have been "let's just wait, and do nothing, and see what happens, until we get moire data a few years from now"?


    When Covid hit, there were a lot of unknowns about it. Policy decisions were needed, and may have been made in times of insufficient information. That is not the same thing as misinformation.


    Sadly, this sort of comment has been typical of what David-acct tends to post here.

    Inoculation against mis- and disinformation doesn't involve censorship but making people aware of the techniques involved with spreading it. The only people who could have anything against that are the spreaders of disinformation, everybody else should be happy about those efforts in order to no longer fall for it.

    he calls to suppress "disinformation" are effectively calls for censorship. In the long term, Censorship is far greater threat to democracy and the freedom of expression and scientific thought than the spreading of disinformation. Even if its called stopping disinformation, the reality is it a call for censorship.


    I agree that there was a lot of disinformation regarding covid coming from the denialists such as vaccine safety, ivermectin, Hcx. Those claims persisted in spite of good research demonstrating that those claims were crap. However, the amount of disinformation coming from the political leaders and the CDC using low quality studies overhyping the effectiveness of the lockdowns, overhyping the effectiveness of masking and overhyping the effectiveness of the vaccines was extensive. As of the end of 2022, the CDC still had listed 45+ studies showing the "positive effectiveness" of masking, yet at least eight of those studies have serious shortcomings. For example, the Kansas mask mandated counties vs non mask mandated counties for example, the study period was intentionally cut short because the infection rate was higher in the mask mandated counties post the end of the study period.

    Just Dean @20.


    It is not correct to make a comparison of 2023 with El Niño years 1998 & 2016. We are in the first year of a 2023/24 El Niño and the earlier ones were 1997/98 and 2015/16. 2023 is not the El Niño year in which the temperatures jump.


    (Using ERA5 numbers), if we assume the October anomalies coutinue for Nov/Dec, 2023 would show a record year averaging +0.16ºC above all previous years. 1998 & 2016 saw similar +0.15ºC & +0.18ºC respectively. But 2023 is not another 1998 or 2016. We would have to wait for 2024 to make a comparison with previous El Niño years. And the coming El Niño is not looking anything like 1998 or 2016. It is forecast to be "moderate El Niño event", so more like 2010.


    That is why 2023 is being described as "Staggering. Unnerving. Mind-Boggling. Absolutely gobsmackingly bananas." The big question, which is yet to be answered, is 'Why?'


    2023 temps drivers


    You'll be familiar with this graphic if you follow Jason Box. It well-explains the temperature rise 2014-2023 but it does not show anything that would explain the "staggering, unnerving, mind-boggling & absolutely gobsmackingly bananas" temperatures we've seen over the last five months.


    (If you want to see how bananas, have a play on the UoMaine Climate Reanalyser and compare 2023 with previous years, then blank off 2016-23 and repeat for 'pre-El Niño' 2015. And again for 1997.)


    My suggestion as to 'Why?' is that the Jan 2022 Hunga Tonga eruption which was exceptionally large and being sub-ocean blew large amounts of both SO2 and H2O into the stratosphere. These two would cancel each other out so the rather chilly 2022/23 winter (globally) with the SO2 marginally more powerful. But that SO2 has dropped out now and the remaining H2O is still there providing us the bananas. If this is the situation (& there is satellite data showing SO2 dropping out quicker than the H2O), the bananas do thankfully have a shelf-life.

  • A Frank Discussion About the Propagation of Measurement Uncertainty

    MA Rodger at 07:57 AM on 12 September, 2023

    Bob Loblaw @61,


    I did say up-thread I wasn't going to burrow down into the rabbit holes of Frank's argument. So I haven't look into the references Frank uses to defend his equ 5 & 6. If he were honest about his methods, it should be him explaining why he is right and everybody else wrong. But I note for equ 5 & 6, he only "stands by them."


    The nearest Frank comes to an explanation for his equ 5 & 6, for using the RMS for the uncertainty of the combined average of N uncertainties (rather than dividing by N1/2) is found in the first version of nonsense**, Frank (2010). [**Note this is Frank's temperature record nonsense not him climate model nonsense.]


    Frank (2010) sets out four 'Cases' for combined uncertainties: 1, 2 3a and 3b. All but Case 3b are as you would expect with the RMS being divided by N1/2 and thus for large combinations, uncertainty will tend to negligable values. But Frank (2010) designates the combination of SAT data as Case 3b for which it says:-



    "When sensor noise variances have not been measured and neither their stationarity nor their magnitudes are known, an adjudged average noise variance must be assigned using physical reasoning [see Gleser (1998), 'Assessing uncertainty in measurement' - for PDF download]".



    I've not looked to see if the Gleser reference supports such an assertion but it doesn't sound unreasonable although perhaps for the individual variances rather than for the average of those variance.


    But Frank then goes on to tell us:-



    "For multiple sensors of unknown noise provenance, or for a time series from a single sensor of unknown and possibly irregular variance, an adjudged estimate of measurement noise variance is implicitly a simple average ... of the nominally unique ...  noise variance(s) of the N measurements. The primed sigma [in the shown equation] indicates an adjudged estimate [not a standard varriance] and distinguishes Case 3b noise uncertainty from those of Cases 1-3a.
    "In the case of an adjudged average noise uncertainty, each temperature measurement must be appended with the constant uncertainty estimate.
    [For Case 3b] the mean of a series of N measurements [of t] is the usual Σ(ti)/N, but the average noise uncertainty in the measurement mean is [the RMS x N/(N-1)] [see Bevington & Robinson (2003) 'Data Reduction and Error Analysis for the Physical Sciences' 3rd edn, McGraw-Hill, Boston, p. 58, wi = 1 PDF], with one degree of freedom lost because the estimated noise variance in each measurement is an implied mean. Thus when calculating a measurement mean of temperatures appended with an adjudged constant average uncertainty, the uncertainty does not diminish as 1/N1/2. Under Case 3b, the lack of knowledge concerning the stationarity and true magnitudes of the measurement noise variances is properly reflected in a greater uncertainty in the measurement mean. The estimated average uncertainty in the measurement mean is not the mean of a normal distribution of variances, because under Case 3b the magnitude distribution of sensor variances is not known to be normal."



    I have not delved into the reference to see how it would support Frank's assertion. Well, not yet.

  • A Frank Discussion About the Propagation of Measurement Uncertainty

    Bob Loblaw at 08:40 AM on 2 September, 2023

    ICU: I think you posted comment 56 while I was preparing comment 57.


    In the OP, the MANOBS chart of temperature correction is an excellent example of systematic error in a temperature sensor - and how to account for it. Here it is again, for convenience.


     


    MANOBS temperature correction


     


     If this correction is ignored, we see that there is an additional uncertainty of up to 0.2C in the readings - with the exact value depending on temperature. Since each thermometer is calibrated against a better temperatuer sensor (in a lab), we can adjust the reading based on that known systematic error.


    But error is not uncertainty... but even if we do not know the error, we can account for any fixed error (e.g., Mean Bias Error) by subtracting each individual reading from the mean (i.e, an anomaly). That fixed error is non-random, so it is present in every reading in the same amount - even if we do not know that amount.


    Let me try with a simple equation set: (I know, not that math $#!^ again).


    T1true = T1reading + error1


    T2true = T2reading + error2


    Since we don't know the error (we never can, because anything we compare our reading to also has errors), the unknown is an uncertainty. If error1 and error2 are independent, then all the "combined in quadrature" equations that Pat Frank uses are applicable.


    But what if they are related? In the simple case, where the error is completely systematic and fixed (the MBE describes it all), then error1 = error2. In that case when we do T2reading - T1reading, [error2 - error1] = 0, and we get exactly the correct answer for T2true-T1true, even though we have uncertainty in each individual reading.


    Comments 49 and 50 demonstrate this using real data. The errors are not purely MBE, but correcting for MBE on a monthly basis greatly reduces the uncertainty.


    Much of the literature that Pat Frank references, related to different ventilation shields, different measurement systems, changes in station locations etc., is designed specifically to ferret out the MBE and other systematic errors in temperature measurements. Once that systematic error is identified, it is accounted for through the process of homogenization.


    Pat Frank has no idea how any of this actually works.

  • A Frank Discussion About the Propagation of Measurement Uncertainty

    Bob Loblaw at 08:11 AM on 2 September, 2023

    ICU: I mentioned the randomness issue briefly above, in the blog post and in comments. He makes the argument for non-randomness saying he finds a non-normal distribution. I point out in comment 46 that he is wrong: you can have non-normal, but still random, distributions.


    And he keeps using equations to combine uncertainties that require independence of the variances, which is contrary to his claim of non-randomness. And he uses a multiplier of 1.96 to get 2-sigma from 1-sigma, even though he says that distributions are non-normal.


    In the NoTricksZone post, he argues that covariance is not relevant (in fact, that statistics equations combining variances) are not relevant because uncertainty is different from statistics. So he dismisses the equations I have present in the OP - in spite of the fact that they are listed in Wikipedia's "Propagation of Uncertainty" section. Yet covariance is the key concept that needs to be included when things are not random.


    In comment 21, bdgwx provided a link to JCGM 100:288, which is basically the same as the 1995 ISO Guide to Uncertainty in Measurement. Section 5.2 talks about Correlated input quantities. If you look at section 5.2.1 on page 33, it says (emphasis added):



    Equation (10) and those derived from it such as Equations (11a) and (12) are valid only if the input quantities X are independent or uncorrelated (the random variables, not the physical quantities that are assumed to be invariants — see 4.1.1, Note 1). If some of the Xi are significantly correlated, the correlations must be taken into account.



    The internal inconsistencies in Pat Frank's work are numerous and critical. It's not random, but you don't need to use equations that are designed for correlated inputs. It's not normally-distributed, but you can still get to 95% confidence levels by using the proportions from a normal curve and 1-sigma/2-sigma ratios.


    He's picking equations and terms from a buffet based on taste, having no idea how any of the dishes are made,  and claiming that he can cook better than anyone else.


    In comments 49 and 50, I show data from real world measurements comparing three equivalent temperature sensors, and how you need to properly divide Root Mean Square Error into the Mean Bias Error and standard deviation of differences between pairs to properly evaluate the uncertainty. And how accounting for the Mean Bias Error across sensors (by using anomalies) shows that all three sensors agree on how different the current temperature is from the monthly mean.


    Nowhere in Pat Frank's paper does he discuss Mean Bias Error or any other specific form of systematic error. Every single one of his equations ignores the systematic error he claims is a key point.

  • A Frank Discussion About the Propagation of Measurement Uncertainty

    Bob Loblaw at 05:07 AM on 30 August, 2023

    ...and, to put data where my mouth is....


    I claimed that using anomalies (expressing each temperature as a difference from its monthly mean) would largely correct for systematic error in the temperature measurements. Here, repeated from comment 49, is the graph of error statistics using the original data, as-measured.


    Error statistics - three temperature sensors


     


    ...and if we calculate monthly means for each individual sensor, subtract that monthly mean from each individual temperature in the month, and then do the statistics comparing each pair of sensors (1-2, 1-3, and 2-3), here is the equivalent graph (same scale).


    Error statistics - three temperature anomalies


     


    Lo and behold, the MBE has been reduced essentially to zero - all within the range -0.008 to +0.008C. Less than one one-hundredth of a degree. With MBE essentially zero, the RMSE and standard deviation are essentially the same. The RMSE is almost always <0.05C - considerably better than the stated accuracy of the temperature sensors, and considerably smaller than if we leave the MBE in.


    The precision of the sensors (small standard deviation) can detect changes that are smaller than the accuracy (Mean Bias Error).


    Which is one of the reasons why global temperature trends are analyzed using temperature anomalies.

  • A Frank Discussion About the Propagation of Measurement Uncertainty

    Bob Loblaw at 22:53 PM on 29 August, 2023

    I will not try to say "one last point" - perhaps "one additional point".


    The figure below is based on one year's worth of one-minute temperature data taken in an operational Stevenson Screen, with three temperature sensors (same make/model).


    The graph shows the three error statistics mentioned in the OP: Root Mean Square Error (RMSE), Mean Bias Error (MBE), and the standard deviation (Std). These error statistics compare each pair of sensors: 1 to 2, 1 to 3, and 2 to 3.


    The three sensors generally compare within +/-0.1C - well within manufacturer's specifications. Sensors 2 and 3 show an almost constant offset between 0.03C and 0.05C (MBE). Sensor 1 has a more seasonal component, so comparing it to sensors 2 or 3 shows a MBE that varies roughly from +0.1C in winter (colder temperatures) to -0.1C in summer (warmer temperatures).


    The RMSE error is not substantially larger than MBE, and the standard deviation of the differences is less than 0.05C in all cases.


    This confirms that each individual sensor exhibits mostly systematic error, not random error.


    Error statistics - three temperature sensors


     


    We can also approach this my looking at how the RMSE statistic changes when we average the data over longer periods of time. The following figure shows the RMSE for these three sensor pairings, for two averaging periods. The original 1-minute average in the raw data, and an hourly average (sixty 1-minute readings).


    We see that the increased averaging has had almost no effect on the RMSE. This is exactly what we expect when the differences between two sensors have little random variation. If the two sensors disagree by 0.1C at the start of the hour, they will probably disagree by very close to 0.1C throughout the hour.


    RMSE - three temperature sensors


     


    As mentioned by bdgwx in comment 47, when you collect a large number of sensors across a network (or the globe), then these differences that are systematic on a 1:1 comparison become mostly random globally.

  • A Frank Discussion About the Propagation of Measurement Uncertainty

    Bob Loblaw at 07:01 AM on 29 August, 2023

    Yes, bdgwx, that is a good point. The "many stations makes for randomness" is very similar to the "selling many sensors makes the errors random when individual sensors have systematic errors".


    The use of anomalies does a lot to eliminate fixed errors, and for any individual sensor, the "fixed" error will probably be slightly dependent on the temperature (i.e., not the same at -20C as it is at +25C). You can see this in the MANOBS chart (figure 10) in the OP. As temperatures vary seasonally, using the monthly average over 10-30 years to get a monthly anomaly for each individual month somewhat accounts for any temperature dependence in those errors.


    ...and then looking spatially for consistency tells us more.


    One way to look to see if the data are random is to average over longer and longer time periods and see if the RMSE values scale by 1/sqrt(N). If they do, then you are primarily looking at random data. If they scale "somewhat", then there is some systematic error. If they do not change at all, then all error is in the bias (MBE).


    ...which is highly unlikely, as you state.


    In terms of air temperature measurement, you also have the question of radiation shielding (Stevenson Screen or other methods), ventilation, and such. If these factors change, then systematic error will change - which is why researchers doing this properly love to know details on station changes.


    Again, it all comes down to knowing when you are dealing with systematic error or random error, and handling the data (and propagation of uncertainty) properly.

  • A Frank Discussion About the Propagation of Measurement Uncertainty

    Bob Loblaw at 00:12 AM on 29 August, 2023

    Getting back to the temperature question, what happens when a manufacturer states that the accuracy of a sensor they are selling is +/-0.2C? Does this mean that when you buy one, and try to measure a known temperature (an ice-water bath at 0C is a good fixed point), that your readings will vary by +/-0.2C from the correct value? No, it most likely will not.


    In all likelihood, the manufacturer's specification of +/-0.2C applies to a large collection of those temperature sensors. The first one might read 0.1C too high. The second might read 0.13C too low. And the third one might read 0.01C too high. And the fourth one might have no error, etc.


    If you bought sensor #2, it will have a fixed error of -0.13C. It will not show random errors in the range +/-0.2C - it has a Mean Bias Error (as described in the OP). When you take a long sequence of readings, they will all be 0.13C too low.



    • You may not know that your sensor has an error of -0.13C, so your uncertainty in the absolute temperature falls in the +/-0.2C range, but once you bought the sensor, your selection from that +/-0.2C range is complete and fixed at the (unknown) value of -0.13C.

    • You do not propagate this fixed -0.13C error through multiple measurements by using the +/-0.2C uncertainty in the large batch of sensors. That +/-0.2C uncertainty would only vary over time if you kept buying a new sensor for each reading, so that you are taking another (different) sample out of the +/-0.2C distribution. The randomness within the +/-0.2C range falls under the "which sensor did they ship?" question, not the "did I take another reading?" question.

    • When you want to examine the trend in temperature, that fixed error becomes part of the regression constant, not the slope.

    • ...and if you use temperature anomalies (subtracting the mean value), then the fixed error subtracts out.


    Proper estimation of propagation of uncertainty requires recognizing the proper type of error, the proper source, and properly identifying when sampling results in a new value extracted from the distribution of errors.

  • A Frank Discussion About the Propagation of Measurement Uncertainty

    Bob Loblaw at 09:59 AM on 16 August, 2023

    Bdgwx:


    Thanks for the additional information. From the Bevington reference you link to, equation 3.13 looks like it matches the equation I cited from Wikipedia, where you need to include the covariance between the two non-independent variance terms. Equations 4.13, 4.14, and 4.23 are the normal Standard Error estimate I mentioned in the OP.


    Of course, calculating the mean of two values is equivalent to merging two values where each is weighted by 1/2. Frank's equations 5 and 6 are just "weighted" sums where the weightings are 30.417 and 12 (average number of days in a month, and average number of months in a year), and each day or month is given equal weight.


    ...and all the equations use N when dealing with variances, or sqrt(N) when dealing with standard deviations. That Pat Frank screws up so badly by putting the N value inside the sqrt sign as a denominator (thus being off by a factor of sqrt(N)) tells us all we need to know about his statistical chops.


    In the OP, I linked to the Wikipedia page on MDPI, which largely agrees that they are not a reputable publisher. I took a look through the Sensors web pages at MDPI. There are no signs that any of the editors or reviewers they list have any background in meteorological instrumentation. It seems like they are more involved in electrical engineering of sensors, rather than any sort of statistical analysis of sensor performance.


    A classic case of submitting a paper to a journal that does not know the topic - assuming that there was any sort of review more complex than "has the credit card charge cleared?" The rapid turn-around makes it obvious that no competent review was done. Of course, we know that by the stupid errors that remain in the paper.


    It is unfortunate that the journal simply passes comments on to the author, rather than actually looking at the significance of the horrible mistakes the paper contains. So much for a rigorous concern about scientific quality.


    The JCGM 100:2008 link you provide is essentially the same as the ISO GUM I have as a paper copy (mentioned in the OP).

  • A Frank Discussion About the Propagation of Measurement Uncertainty

    bdgwx at 06:23 AM on 16 August, 2023

    I have had numerous discussions with Pat Frank regarding this topic. His misunderstanding boils down to using Bevington equation 4.22. There are two problems here. First and foremost, 4.22 is but an intermediate step in propagating the uncertainty through a mean. Bevington makes it clear that it is actually equation 4.23 that gives you the final result. Second, Equations 4.22 and 4.23 are really meant for relative uncertainties when there are weighted inputs. Frank does not use weighted inputs so it is unclear why he would be using this procedure anyway.


    Furthermore, Frank's own source (Bevington) tells us exactly how to propagate uncertainty through a mean. If the inputs are uncorrelated you use equation 4.14. If the inputs are correlated you use the general law of propagation of uncertainty via equation 3.13. 


    A more modern and robust exploration of the propagation of uncertainty is defined in JCGM 100:2008 which NIST TN 1900 is based.


    And I've told Pat Frank repeatedly to verify his results with the NIST uncertainty machine. He has insinuated (at the very least) that NIST and JCGM including NIST's own calculator are not to be trusted.


    Another point worth mentioning...he published this in the MDPI journal Sensors. MDPI is known to be a predatory publisher. I emailed the journal editor back in July asking how this publication could have possibly made it through peer review with mistakes this egregious. I basically explained the things mentioned in this article. The editor sent my list of mistakes to Pat Frank and let him respond instead. I was hoping for a response from the editor or the reviewers. I did not get that. 


     

  • Increasing CO2 has little to no effect

    Paul Pukite at 22:27 PM on 18 July, 2023

    Most of the major climate indices (ENSO, AMO, PDO, QBO, AO, SAM, MJO, NAO, SOI) show no signs of AGW, as the characteristic secular trend is missing, The only one that does is the IOD, as the West IOD shows a much larger trend than East. In any case, all the indices can be explained by a tidal mechanism, which should be good news to those that worry that natural climate change has no constraints — tides always revert to a mean of zero => https://geoenergymath.com/2023/07/17/the-big-10-climate-indices/

     "You have no objective criteria to declare that The Battery and Honolulu are "the best" at representing anything other than local effects..."


    The Battery has 1825 months of sea-level measurements. No other NOAA Atlantic site has that much. Only San Francisco has more, but it has only 1404 months of measurements since the 1906 earthquake. The downside to The Battery's measurement record is its high (atypical) rate of subsidence, which roughly doubles the local ("relative") sea-level trend there.


    There are some European sites with longer, better Atlantic / North Sea / Baltic measurement records, and Australia has an excellent Pacific measurement record, but there are substantial delays getting data for those locations. My sealevel.info stie pulls data from NOAA frequently, so it's much more up-to-date.


    Some of the European sites, have recorded a slight acceleration; it was most noticeable at Brest, which saw a 0.0 mm/year trend in the19th century, but a 1.6 mm/year trend since then, though there are substantial gaps in ther record.


    Several German sites have particularly excellent measurement records; here's one of them:


    Travemunde sea-level


    In the Pacific, Honolulu has 1421 months (>118 years) of continuous sea-level measurements, without even a single missing month. Just as importantly, Honolulu is a near-ideal measurement site, near the middle of the world's largest ocean, on an "old" island with near-zero vertical land motion, small tides, and (unlike most places!) almost no seasonal cycle. What's more, its mid-Pacific location is near the pivot point of the east-west Pacific "teeter-totter," so it is little affected by ENSO "slosh." That is, El Niño and La Niña don’t affect sea-level there much at all. It really is a superb dataset.


    Bob continued, "Just because they have long records does not mean that they accurately reflect regional or global trends."

    That's true. As I've mentioned, NYC's sea-level trend is atypical, because of the high rate of subsidence there.

    However, if subsidence / uplift are due to very long term processes, like PGR, there's reason to hope that they are fairly consistent over the duration of the measurement record. In that case, even if the linear trend is greatly affected by uplift or subsidence, the acceleration won't be. (Of course, that doesn't work in places, like Manila, where changing local factors, like groundwater pumping, cause varying subsidence.)


    So it should not surprise you that, even though The Battery and Honolulu have seen quite different linear trends over the last century, the measured acceleration in both places is very similar (negligible).


    Bob wrote, "You are clearly picking locations to try to tell the story you want to tell."


    That's a false accusation. You just find the data surprising, so you make baseless accusations, without evidence. That is not conducive to constructive dialogue, nor to learning.


    If you think I chose unrepresentative sites, or sites with inferior quality measurement data, then YOU tell me what sites YOU think are better, and why.


    Bob wrote, "As for your quadratic fits: it has been pointed out to you over the past 10 years that quadratic fits mean nothing when the underlying data does not resemble a quadratic relationship."


    Nobody competent makes that claim in the context of sea-level analysis.


    If there were a step-change in some climate system input, then you could look for a step-acceleration as a consequence. But there's been nothing like that. The radiative forcing trend from CO2 has been very gradual, and strikingly linear (just barely more than linear) for the last forty years. It's been quite gradual for much longer than that.


    Quadratic regression is the cannonical way of detecting gradual acceleration. It's how Church & White did it, and how every competent sea-level analyst since then has done it. When Hogarth reported that, "sea level acceleration from extended tide gauge data converges on 0.01 mm/yr²," that's what he was talking about.

  • CO2 effect is saturated

    bobhisey at 21:30 PM on 12 July, 2023

    My arguement is not against global warming, but in falsely ascribing it to CO2.


    The NASA data on the absorption of earth's radiation show clearly that no energy is leaving the earth in the 14-16 micron band.  This is the only significant absorption band for CO2 absorbing our radiation.  Snce it is saturated/opaque, more CO2  has no effect.


    This causes the earth to warm up a bit to increase radiation in other wave lengths and balance out the loss in the 14-15micron range.  


    This very detailed Nasa data can now be found at NASA Technical Memorandum 103957, Appendix E.  All 90 pages of it.  It was produced in 1992, but was unavailable to the public till now.  However, it has been in use by theNASA  Infra-red astronomy project Gemini, for over 20 years, proving its validity.


    Previously the best data available was from the 1960's NASA  Nimbus satellite.  This utilized a very broad band sensor, seemingly like 20microns.  This obviously could not pick up a 2 micron minimum band and  gave a gently curved spectrum showing a maximum absorption of about 50%.  


    A full discussion can be seen in "Carbon Dioxide - Not Guilty" on kindle for 99c.


    My conclusion is the CO2 is not the cause of our global warming, and I have no idea as to what is the cause.  We are wasting our time and money on a false premise, and should rather find the real cause.

  • 7 TV meteorologists discuss their coverage of climate change and weather

    One Planet Only Forever at 06:19 AM on 12 July, 2023

    An update regarding a couple of the passionate helpful meteorologists covered in this article:



    Nasty 'learning resistant people' will always be around. But it is very important, and very challenging, to keep on disappointing them no matter how angry they get ... as long as others are also being communicated to and can see how harmfully incorrect the 'learning resistant people', and their preferred type of leaders, are.

  • Hansen predicted the West Side Highway would be underwater

    daveburton at 07:21 AM on 7 July, 2023

    Michael wrote, "the last time Carbon dioxide was over 400 ppm the sea level was more than 20 meters higher than current sea level."


    Yes, many things were different 4.5 million years ago. They weren't all caused by CO2.


    For example, the highest-quality Pacific sea-level measurement record is from Honolulu, on Oahu. But it would be difficult to say anything meaningful about how sea-level there has changed since CO2 levels were last this high, because Oahu (and the Big Island) didn't exist 4 million years ago!



    Michael wrote, "Your sea level graphs are obviously flawed."


    I guarantee that they are not flawed.


    They are accurate plots of sea-level measurements at those two sites, which are the best long NOAA Atlantic sea-level measurement record (The Battery, NYC), and the best long NOAA Pacific sea-level measurement record (Honolulu, HI). The linear and quadratic regressions are accurately calculated from the most recent 100 years of data at each site, shown with deep blue traces. Earlier data (not included in the regressions) is shown in light blue.


    If you click the links, you can adjust the measurement periods over which the regressions are calculated, and see the effect of those adjustments. You can also smooth the plots, and choose whether to plot linear and/or quadratic fits, as well as confidence and/or prediction intervals. At the top of each graph you'll also find links to the corresponding NOAA and PSMSL web pages for those sites. You can also do the same analyses for other NOAA measurement sites, and for over 1000 sites with data available from PSMSL (though the PSMSL data aren't as up-to-date as the NOAA data).



    Michael wrote, "you have cherry picked two single locations to do your calculations without justifying your choice."


    They aren't "cherry-picked," I told you why I chose them: they are "the best long U.S. Atlantic and Pacific sea-level measurement records, respectively."


    The analysis period of 100 years is arbitrary, of course, but if you click the links which I provided you can easily change it:
    https://sealevel.info/MSL_graph.php?id=Battery&c_date=1923/6-2023/5
    https://sealevel.info/MSL_graph.php?id=Honolulu&c_date=1923/6-2023/5


    I also reported the conclusion of a comprehensive study: "Hogarth studied many long measurement records, and concluded, 'Sea level acceleration from extended tide gauge data converges on 0.01 mm/yr²'" (That's negligible, BTW.)


    Beware of "global" sea-level analyses which use varying mixes of measurement locations. As you can see from the striking difference between Oahu and New York, sea-level trends vary considerably from one location to another. So if you use a different mix of measurement locations for the left and right ends of a plot, you can easily create the illusion of a sharp acceleration or deceleration which is not evident in the individual measurement records.


    Also, beware of the fact that there are also regional effects, in some places. For example, ENSO causes changes in low-latitude easterly Pacific trade winds. During El Niños easterly Pacific equatorial trade winds diminish, so the Pacific ocean sloshes east, raising sea-level in the eastern Pacific, and lowering it in the western Pacific. This is very striking when you compare the sea-level measurement records of Kwajalein (in the western Pacific) and San Diego (in the eastern Pacific). They are almost perfect mirror images!

    Correlation of sea-level with ENSO at Kwajalein and San Diego


    (One of the nice things about Honolulu is that it is near the ENSO "teeter-totter pivot point," so, unlike other long Pacific sea-level measurement records, Honolulu's is scarcely affected by ENSO.)


    Another example of regional effects is the southeastern United States, where Gulf Stream variations are apparently the cause of well-known multi-decadal fluctuations in sea-level trends. For a discussion see Zervas (2009), NOAA Technical Report NOS CO-OPS 053, Sea Level Variations of the United States, 1854-2006. Here's a relevant excerpt:

  • Skeptical Science New Research for Week #25 2023

    One Planet Only Forever at 06:24 AM on 25 June, 2023

    BaerbelW,


    The education-related action by Finland is a helpful action in parallel with, but not part of the scope of, the UN actions regarding Information Integrity on Digital Platforms.


    A major 'non-censorship' action discussed in the UN document is developing ways to effectively keep disinformation, misinformation and hate messages from being profitable, especially by controlling advertising placement. A related action would be for responsible advertisers to stop advertising on platforms that do not effectively do that.


    During my MBA education in the early 1980's my course on Marketing began with the professor telling us that we will be learning about the ability to be temporarily successful by being misleading and warning us about the unsustainability of that Marketing approach.


    Attempts to benefit from Disinformation are nothing new. Digital Platforms are just the latest, and potentially most damaging, development that can be abused that way, especially with the rapid unregulated development of AI.

  • Skeptical Science New Research for Week #25 2023

    One Planet Only Forever at 05:47 AM on 25 June, 2023

    Nigelj,


    I am responding hoping to encourage you to read the UN document about Information Integrity on Digital Platforms.


    I agree that Harari’s “21 Lessons for the 21st Century” (and “Sapiens”) are helpful presentations. I read both books a while ago. Your comment prompted me to revisit “21 Lessons ...”


    “The Ecological Challenge” sub-section of the “Nationalism (Global Problems Need Global Answers)”, a chapter about the problems caused by nationalism, is aligned with the new UN initiative regarding the harm of successful disinformation production and promotion. Another tragically relevant chapter today is the “Post-Truth (Some Fake News Lasts Forever)” chapter.


    The item from Harari’s book that seems most relevant to the new UN initiative is from the “Education (Change Is the Only Constant)” chapter. Though not explicitly stated, the implication is that people who resist increasing their awareness and resist improving their understanding of what is harmful and helpful to the development of sustainable improvements for the future of global humanity ‘will potentially need legal or other government actions to limit the harm done by their preference for preserving a misunderstanding or lack of awareness’.


    In the chapter on Education, Harari makes the following important point:


    So what should we be teaching? Many pedagogical experts argue that schools should switch to teaching “the four Cs” – critical thinking, communication, collaboration, and creativity. More broadly, they believe, schools should downplay technical skill and emphasize general-purpose life skills. Most important of all will be the ability to deal with change, learn new things, and preserve your mental balance in unfamiliar situations.


    The new UN initiative regarding the harm of disinformation, misinformation and hate on digital platforms, including its further development and implementation, is a “four Cs” type of action.


    I would encourage you to read the complete UN document. Though I can quickly scan a document, when reading I am usually slower than others because I tend to read every word. It took me 40 minutes to read the entire text (not reading footnotes). For comparison, the Harari sub-section on The Ecological Challenge was a 10 minute read. And it is only 1/4 of the important “Nationalism” chapter. And that entire chapter is only 6% of the book’s ‘well worth reading’ content.


    Regarding your stated concern:


    However I'm not too keen on governments or the news media or other organizations becoming censors of information. I read George Orwells book 1984 recently and it certainly does a good job of raising awareness of the dire consequences of governmnet and media censorship even if it's well meant.


    Of course we do have some established and reasonable limits on free speech, like laws against inciting violence but they are minimal and related to law breaking. I'm talking about going beyond this.


    Your concern is addressed in the UN document. Also, the interventions you are accepting are ‘interventions to limit harm done’. That is, or should be, the fundamental principle of laws and their restrictions of freedom. Tragically, I agree that sovereign national or regional governments and pursuers of profit cannot be trusted to constantly govern their law-making, regulation-creation, enforcement or other actions to limit harm done. Pursuits of popularity and profit can create interests for individuals and sub-groups of global humanity that are in conflict with correcting harmful developments and conflict with developing sustainable improvements for global humanity. Those damaging ‘developed and developing conflicts if interest’ include the potential for the sub-group of ‘all of current-day humanity’ having interests that conflict with the development of a sustainable improving future for global humanity.


    So, Harari’s book is informative and exposes many important issues. However, the UN document is doing the harder work of applying the ‘four Cs’, to develop global change regarding the integrity of digital information to limit harm done. The section titled “What is the relevant international legal framework?” (page 9) addresses the matter of free speech (as do other parts of the document). It is less than a 3 minute read and opens and ends with:


    The promotion of information integrity must be fully grounded in the pertinent international norms and standards, including human rights law and the principles of sovereignty and non-intervention in domestic affairs. In August 2022, I transmitted to the General Assembly a report entitled “Countering disinformation for the promotion and protection of human rights and fundamental freedoms”.15 In the report, I laid out the international human rights law that applies to dis-information, including the Universal Declaration of Human Rights and the International Covenant on Civil and Political Rights. Under these international legal instruments, everyone has the right to freedom of expression.16
    ...
    In its resolution 76/227, adopted in 2021, the General Assembly emphasized that all forms of disinformation can negatively impact the enjoyment of human rights and fundamental freedoms, as well as the attainment of the Sustainable Development Goals. Similarly, in its resolution 49/21, adopted in 2022, the Human Rights Council affirmed that disinformation can negatively affect the enjoyment and realization of all human rights.


    And the following is a quote from the beginning of the section titled “Towards a United Nations Code of Conduct UN” (page 21):


    The United Nations Code of Conduct for Information Integrity on Digital Platforms, which I will put forward, would build upon the following principles:
    • Commitment to information integrity
    • Respect for human rights
    • Support for independent media
    • Increased transparency
    • User empowerment
    • Strengthened research and data access
    • Scaled up responses
    • Stronger disincentives
    • Enhanced trust and safety


    I encourage people who are concerned about the harm of disinformation to take the time to read the full UN document.

    "However I'm not too keen on governments or the news media or other organisations becoming censors of information."



    There are other means organizations can prevent - or at least minimize - the spread of misinformation. Warning messages that content has been contested for example, or a setup that would-be commenters or sharers first have to answer a question related to the article before they can do either.


    And then, there's that whole idea of inoculation, that goes along with improving media literacy of large swaths of the population. Imagine how effective it would be, if nobody falls for all the FLICC-techniques any longer and mis- and disinformation than no longer gets shared? Finland seems to be well ahead of many other countries in that regard, based on this article published recently:

    The misinformation is very troubling. The climate denialists are still very active although its swiched to some extent from denialism about the science, to denialism about the impacts of climate change and the solutions.


    However I'm not too keen on governments or the news media or other organisations becoming censors of information. I read George Orwells book 1984 recently and it certainly does a good job of raising awareness of the dire consequences of governmnet and media censorship even if it's well meant.

    But at he same time the way Musk has allowed twitter to revert to an open slather for hate and misinformation is equally as troubling. It all leaves me unsure what the best solution is. 


    However there is no justification for algorithms that send people a deluge of climate denial. This is just manipulation to increase profits.


    I recommend this book to people: 21 lessons for the 21st century by Yuval Harari. Very good chapter on climate change and other environmental issues. IMO this man has a great grasp of reality.

    "Nobody knows.." Hmm. Certainly investigated. See "Interannual ice mass variations over the Antarctic ice sheet from 2003 to 2017 were linked to El Niño-Southern Oscillation"


    Shows correlation of AP and WAIS with ENSO and anticorrelation of EAIS.



    Hmm. ok, only 2017. What about GFO and recent records. There is some detailed analysis in "Spatially heterogeneous nonlinear signal in Antarctic ice-sheet mass loss revealed by GRACE and GPS (2023)"


    and another study of links with other quasi-periodic cycles in Antarctica in "Antarctica ice-mass variations on interannual timescale: Coastal Dipole and propagating transports"


    Evidence to date - based on correlations of where the changes in ice mass are occurring - links interannual change to short term (2-8 year) quasi-periodic weather cycles (ENSO, Antarctic Circumpolar Wave, Antarctic Occillation) influencing Antartica.


    My money (literally) would be on continued long term ice loss. Short term variation as observed here to date would certainly NOT be a reason for change in climate mitigation policy.

  • Two attempts to blame global warming on volcanoes

    JohnSeers at 23:06 PM on 4 April, 2023

  • It's the sun

    MA Rodger at 02:10 AM on 12 February, 2023

    The link given @1305 leads me to a bunch of YouTube adverts but if you specify a time with the link, the Curry/Peterson nonsense appears. Thus:
    https://www.youtube.com/watch?v=9Q2YHGIlUDk&t=60s
    Below the video there is a box that can be expanded with a 'show more' tab and that shows a list of a couple of dozen parts to the video (called Chapters) and one of these does mention things solar (which was what panhuag @1306 was asking about) 'The Challenger explosion, how the sun affects climate'. This provides the following from Curry:-



    "Once you get into the sun, it's even crazier. The IPCC has pretty-much dismissed the role of the sun in the last 150 years but the interesting AR6.6 finally acknowledged the great uncertainty in the amount of solar forcing in the late 20th century and this arises from ... a gap in the satellites measuring the sun's output that occurred at the time of the Challenger shuttle disaster... So one solar sensor was running out and they were supposed to launch another one but all the launchers were put off for a number of years until they sorted out... (the launchers). So there's a so-called gap which depending on what was happening in that gap, you can tune the solar variability to high variability or low variability. So all the climate models are being run with low solar variability forcing.
    For the first time in AR6.2 (2.2.1), the observational chapter acknowledges this issue, that there are huge amounts of variability.
    And this doesn't even factor in the solar indirect effects.... It's not just the heat from the sun. There's a lot of issues related to UV and stratosphere and cosmic rays and magnetic fields and all these otehr things that really aren't being factored in. They're at the forefront of research but they're certainly not factored into the climate models so there are so many uncertainties out there that affect certainly the projections of what might happen in the 21st century but also our interpretation of what's been going on with the climate for the last 100 years and exactly what's been causing what.



    A quick look at AR6.2.2.1 shows Curry is doing particularly well ast spouting nonsense here.

    Note that the data for global temperatre you plot is NOAA data but not GISS (LOTI) data. Both use the same raw data but process them differently. Thus in NOAA 2015 is warmer than 2017 by +0.02ºC while in GISS 2015 is cooler than 2017 by -0.02ºC.


    And both have published the 2022 figure which slots into the record above 2021, although not by much in NOAA.


    As you rightly say, the present La Niña is depressing the global average SAT, a La Niña which is expected to end through the coming year, and expected to end a lot more suddenly than previous strong La Niñas (like 1988, 1999 & 2008 which were more sudden transitioning into La Niña and more gradual transitioning out).

  • We’ll keep tweeting (for now) but have also started tooting.

    One Planet Only Forever at 15:15 PM on 4 January, 2023

    Peppers @91,


    The population issue may be better understood by performing the mental exercise of considering a case where the global population did not increase above 800 million.


    If, by today, the 800 million developed to be as harmful ‘annually in total’ as the current most harmful 800 million are, then the magnitude of harm done so far, and rate of harm done, would be less than the current problem of the 8 billion today. More people being harmful, even if they are less harmful people, will produce harm more rapidly. But the continued increase of harm done at a lower rate would eventually produce a similar level of harmful results.


    Once the harm being done was recognized (understandable) as something that had to be ended and undone (in spite of harmful efforts to promote misunderstanding, and ask questionable questions that have understandable answers, to delay the awakening of that understanding – prolonging understandably harmful misunderstandings that delay the reduction of harm being done), if each of the 800 million had developed a reasonably comparable level of harmfulness then they would all have a comparable responsibility for reducing their harmfulness. However, if the distribution of harmfulness was similar to the current distribution (refer to my comment @82 - the top 10% of the 800 million being as harmful as the top 1% of 8 billion, and the top 1% being like the current top 0.1%) then the common sense would be that the more harmful people, all of them, would need to more rapidly and more dramatically lead the learning and correction of behaviour.


    The problem is the examples being set by the supposedly more advanced portion of the population, combined with the development of desires in more people to develop to live that way (as you say “they too want to live as full a life as possible” incorrectly believing that ‘desiring to be more harmful’ is ‘Living fuller’ or that ‘living fuller’ excuses the harm done). That harmful result is unjustified and relies on harmful misunderstandings like the following (refer to my comment @90 for an alternate presentation of the same point):



    • those who are first to develop more harmful ways of living get to be more harmful

    • harmfulness has to be accepted, because some people desire things that are understandably harmful


    My point, unaltered by anything you have presented, is that unless there is a systemic ideological change that establishes the common sense that it is unacceptable for ‘desires’ to be obtained harmfully then any ‘solutions’ will likely be harmful and ultimately unsustainable.


    Fundamentally the developed common sense understanding includes:



    • the harmfulness of people continuing to ‘pursue desires (not needs)’ via harmful fossil fuel use is now undeniable because of climate science.

    • the development and proliferation of misunderstandings about climate science, including questionable questions related to the need for the most harmful people to most rapidly limit their harmfulness, is undeniably harmful because it delays the limiting of the harm done.

    • pursuing ‘solutions’ without acknowledging that only ‘meeting everyone’s basic needs’ is allowed to be harmful (with as little harm done as possible) will not produce sustainable solutions.


    The problem is not solved by the development of new technology or 'other solutions' in a system that does not recognize the need for ‘desires beyond the basic needs of living’ to be harmless. The desire for people to maintain and increase developed perceptions of ‘fuller’ living does not justify the added harm done while they try to delay the understanding of the growing urgency for their desired harmful actions to be more rapidly ended.


    Also, harmful climate change impacts due to fossil fuel use were the result of the pursuits of status through technology development competition in a system with success measured by popularity and profit. It is also common sense that some people harmfully resist learning about the harmful results of persistent and prolific presentations of misunderstandings regarding climate science. Even without the harmful delay of persistent misunderstanding, it is understandably unacceptable to ‘wait for the obviously harmfully inclined competition to end the harm it developed’. There is abundant evidence that limiting of harm done by activity related to fossil fuels (and other activities) has almost only ever happened through ‘regulation and restriction by Others who govern based on the pursuit of increased awareness and understanding of what is harmful’. Examples abound including: ending lead in gasoline, reduction of sulphur emissions, reduced particulate emissions, and improved fuel efficiency.


    As for your point “I cannot censor others because I now want to call their opinion harmful misunderstandings”. That is a version of an already pointed out misunderstanding/misrepresentation of my presented points. One more time, stated a different way:



    • the most serious population problem related to ‘climate science and understood to be harmful climate change impacts of human activity’ is the most harmful impacting portion of the population.

    • the harmful portion of the population is not excused by claiming that ‘others want to be like them’.

    • the small percentage who are most harmful are not excused by claiming that large numbers of other less harmful people are a bigger concern.

    • continuing harmful activity that is unnecessary for decent basic living is not excused by claiming that harmless ways to do the desired things ‘will be developed’. Maybe they won’t be developed. Maybe harmful replacements, only a little less climate change harmful or harmful in other ways, will be used. Note that stopping unnecessary harmful activity would limit the harm done ‘and’ motivate the development of harmless ways to meet those unnecessary desires.

    • it is harmful to maintain a misunderstanding that evades learning that fossil fuel use must be rapidly ended by the people who cause the most harm due to their harmfully over-developed ‘unnecessary’ fossil fuel use.

    • the real root of the problem is the development of desires for over-consumption including energy over-consumption.


    You say “Yet we have let 11 million (from lower per capita impact nations) in to our 15.52 per capita USA.” That is an argument against yourself. You have essentially stated that it is expected and OK for lower impact people to develop higher impact ways of living. Also, people moving to the USA would not be a problem if all of the USA, not just some portions of its population, were leading the awakening of the understanding of the need for a rapid transition away from the ideology that harmful ways of obtaining ‘desires’ are excusable.


    In conclusion, I believe it is important for SkS to continue to raise awareness (awaken people) regarding the climate science understanding that results in people learning to be less harmful, including voting for representatives who will be less harmful and more helpful leaders. That includes efforts on Twitter until it becomes clear that there is no longer a significant number of people remaining on Twitter who are interested in developing the common sense understanding of the need to rapidly end fossil fuel use and curtail other harmful ‘desired activity’.

    HI One Plant,


     


    I really appreciate discussing this w you. Much of this topic of population is to be based in common sense. The new input taking us from 1 to 8 billion now, it happened all across the world. America tripled, China tripled adding a billion. The starving areas represent about a billion, just under I hope, and once they get past finding food security, they too want to live as full a life as possible. So I think there is a narrowing as new tech makes more available, more will step up wanting it and being able to access it. Many examples of tech/competition working toward that. And as we get back on track to solve world hunger, there is another original billion, as the number we started with in 1900 again, ready to add thier consumerism, for a better life, for the same reasons we chose it as well.


    I think a larger solution needs considering, and atomic would fill that bill.


    The fossil fuel is why the co2 has increased, and mostly its manmade. But we cannot undo 8 billion, going to 10 they say.


    This is my opinion, and it is where all ideas begin, as opinions. I cannot censor others because I now want to call their opinion harmful misunderstandings. Thats the primary point I had. Its that you cannot say you are right and all others are wrong, because we cant do that. Its not aggresive or meant to down anywhere. But we have to keep thinking to work on anything, and freedom to think and express is very much desirable. If you say I am right and all else are harmful misunderstandings. Well.


    Mexico is a per capita rate of 3.58 for Co2, Venesuela 5.89. Yet we have let 11 million in to our 15.52 per capita USA. Political is against us. Natural thriving is against. This is only for me Forever, but an approach that can address this has me running in to all these factors, as I try and understand it to formula a solution.


    But this does not make me a harmful misunderstander.


    Thanks tons, D

    Reviewing all of the comments helped me develop the following response to peppers @86. I hope it is helpful.


    The following questions hopefully establish a common understanding regarding the harm done by the proliferation of misunderstandings on a public-service system like Twitter.


    Note: The harmful results of efforts to delay or diminish the awakening of understanding of harm being done, including the attempts to over-power or threaten people who try to help others learn to be less harmful, is not restricted to climate science.


    Important questions for everyone:


    1. Do you understand how Bayes’ theorem explains the way (perhaps the only way) that humans ‘minimize conflict of interests by developing and improving common sense understanding’? Ideological indoctrination will make people resist following Bayes’ theorem and fail to develop common sense understanding. Problematic beliefs include:



    • cheaper and easier (or more profitable, or more desired) justifies/excuses harm done

    • richer and more powerful people are excused for being more harmful because they can afford to, and are able to, be more harmful

    • harm done (to Others) can be excused if benefits are obtained (by the In Group).


    Ideological beliefs can reduce conflicts within a group (or nation or group of nations). But the resulting group will increase their conflict with Others. Limiting the harm of global conflict requires everyone, or at least all leaders, to apply Bayes’ theorem in pursuit of improved awareness and understanding of what is harmful and how to be less harmful and more helpful to Others (that is the origin of important learning and presentations of understanding like the Universal Declaration of Human Rights, the IPCC, and the Sustainable Development Goals).


    2. Do you accept that all of the Climate Myths presented under the Arguments tab are misunderstandings that everyone can learn to better understand? If not, revisit the Arguments after understanding the next question.


    3. Do you accept that it is harmful to believe and propagate misunderstandings that would delay learning about the importance of rapidly ending fossil fuel use? Wouldn’t it be easier for everyone to learn to be less harmful and more helpful if there was less repetition of harmful misunderstandings, less temptation to excuse harmful actions? Wouldn’t it be better if there was a public gallery of misunderstandings with comprehensive, open to improvement, explanations everyone could learn from (like the SkS Arguments list)? Wouldn’t it be great if every posting that included a repetition of a misunderstanding directed viewers to the appropriate, already established, educational rebuttal?


    4. Do you accept that a high level Ethical/Moral Rule is “Be less harmful (when possible)”? I admit that being harmless is not possible. To live you have to harm other life. But sustainable living is possible. It requires distinguishing ‘Needs essential to living’ from ‘All other desires’. The harm done by meeting essential needs can only be limited to ‘pursuing the least harmful ways to ensure those essential needs are met – By/For Everyone’. Desires, however, are not necessary. Desires should be screened/governed/limited so that the only desires acted on would be sustainable (without accumulating harm) if everybody did the desired action to the same degree (relates to the problem of developing people being tempted to want to live like the harmfully over-developed who are perceived to be superior).


    That brings us to the population question raised by peppers. More people on the planet does result in more restrictions on ‘desired actions’. It also makes the provision of everyone’s essential needs more harmful. An understood solution is pursuing, and improving on, the Sustainable Development Goals (SDGs). Learning about the SDGs leads to understanding that pursuit of the goals would reduce the harmfulness of the developed and developing populations. And a recent research report in the Lancet “Fertility, mortality, migration, and population scenarios for 195 countries and territories from 2017 to 2100: a forecasting analysis for the Global Burden of Disease Study” indicates that achieving the SDGs would also be expected to reduce the peak global population, primarily due to the birth-rate reductions expected to occur in societies with ‘more educated and freer women’.


    Also, the more harmful the climate change impacts are the harder it is to achieve the SDGs. Exceeding 1.0 C of impact has been identified as entering the realm of significant risk of harm. Refer to my comment regarding the Story of the Week “1.5 and 2°C: A Journey Through the Temperature Target That Haunts the World” in the “2022 SkS Weekly Climate Change & Global Warming News Roundup #50”


    With the above established, responses to specific statements made by Peppers @86 are as follows:


    Responding to the population question point that “The causation is fossil fuels, the proliferation of them. But if it is the explosion of bodies from 1 to 8B, exactly matching the rise of Co2, is ID'd as the cause, then our solution would be re-thought as well.”


    nigelj’s response @88 is great. But there is more.


    The problem is admitted to be fossil fuels. But there is no admission of the need to ‘end the harm of fossil fuel use’. Not mentioning the harmful unsustainability of the ways of living developed by the ‘supposedly more superior people that Others aspire to be like’ indicates a lack of understanding of the basics of the issue (refer to the questions above).


    Also, saying “An important part of my 8 billion comment goes past the division of consumption calcs, which I understood too...”, indicates more may be going on than a lack of understanding. Claiming that the comment regarding population “looks past” the fact that a small portion of the population has massive harmful impact is questionable. It is looking through, or looking around, or looking away from the understanding that more harmful people have to make more, and more rapid, corrections of how they live and that developing people should be helped to develop more sustainable lives with the least harmful transition through the fossil fuel use phase of development (waiting for technological developments that will be cheaper and more popular to end the harm done will fail without increased awareness and effective governing to limit misunderstanding and related harm done. Technological solutions, like nuclear, could be unsustainable and harmful like the problem they were believed to solve).


    The problem is made worse by people perceiving the more harmful people to be superior. That misunderstanding could cause people to want to develop to be ‘part of that group and live like they do’. Developing a sustainable solution requires all of the ‘perceived to be superior people (not just the ones who care to learn to be less harmful and more helpful to Others)’ leading the rapid transition/correction past (away from) fossil fuel use.


    Responding to the “One Planet, If you can decide your are so correct in defining that more input is deemed impossible to add anything, then you could move forward with the censoring and re-education plan. The world has seen that before however, and they are still reflecting, what were we thinking?”


    Common sense understanding of the pursuit of improved awareness and understanding of what is harmful and how to be less harmful and more helpful to Others is not ‘my decision or definition’. It is common sense ethics/morality.


    Claiming that limiting the influence of the proliferation of misunderstanding is ‘censorship’ is a misunderstanding.
    Using the term re-education rather than saying ‘learning to be less harmful and more helpful to Others’ is a misrepresentation because re-education has negative connotations that do not apply to learning to be less harmful and more helpful.


    What the world ‘has seen before’ is the result of harmful misunderstandings becoming popular and powerful. That results in ideological indoctrination of populations (with nationalism and other selfish interests). And that causes the resulting population to powerfully and harmfully conflict with Others. They collectively resist learning to be less harmful and more helpful to Others. People should reflect on ‘Seeing what happened’ (continues to happen) within many political groups in many nations. Many groups become increasingly resistant to learning about ‘the harmful results’ of fossil fuel use. People should also reflect on and how other harmful beliefs are embraced by those groups as they ‘wrap themselves in flags’ and pursue the ability to have more influence to be more harmful.

    One Planet, thanks for quoting me.


    An important part of my 8 billion comment goes past the division of consumption calcs, which I understood too; the case load on affecting Co2 is more in the developed nations. But all these new people are not static. They all want how others live as well, once they get past that days meals. 91% of the world having a smartphone just indicates, everyone wants one. And everyone wants to live as involved a life as they can achieve the lifestyle of. The causation is fossil fuels, the proliferation of them. But if it is the explosion of bodies from 1 to 8B, exactly matching the rise of Co2, is ID'd as the cause, then our solution would be re-thought as well. Corobaration of this would involve; has there been a rise in fossil burning vehicles and equipment, the movement of the secondary market of prior technology in to 3rd world areas, etc. As technology progresses to solve these emitters, as anything becomes cheaper and more prevalent, it will also increase in quantity of use as there is a horde of new people waiting to rise in comsumptive activity.  This cannot be a toss away factor. I am interested in this  800% population increase factor.


    Free speech is a nessesity in seeking truth. It may be inconvienient, but I would not want to be wrong because I wouldnt listen anymore.


    NIgelj, your Regarding Hate Speech in 83 nails it. It is deciding definitions that is the core of the concepts problem.


    One Planet, If you can decide your are so correct in defining that more input is deemed impossible to add anything, then you could move forward with the censoring and re-education plan. The world has seen that before however, and they are still reflecting, what were we thinking? There is no solice in numbers. Its an understandable impatience but a wrong conclusion (for me). 


    You have good input about my mention of sueing people who make false statements about someone/something. If categorized as regulating, I would not want more regs to even more regulate an area. Do we need more legal, etc.? To combat disinformation, maybe an action in to journalism, which starkly divides news from editorial. The news area would have to be heavily proved (or not stated there then) and all else can exist in editorial. Disinformation would be harder or not possible to pass as fact then?


    Thx all, D

    Regarding twitter. I think OPOF is right about twitter. If it was to devolve into a cess pool of mostly obnoxious people spreading hate or misinformation you would probably not want to be part of that. Even if you used twitter just to connect with sensible people, it may be a bad look to be part of the twitter system. 


    Regarding free speech and suing people. If people had the ability to sue other people in civil court just because they didnt like what someone said, or they felt it was misinformation or hateful speech, I fear this would have a destructive effect on discussion, because plenty of people  would no longer participate in discussions out of fear of being sued. So such a proposition would be anti free speech.


    I understand that Alex Jones was convicted for making false claims about a  school schooting, but that was under a fairly narrowly focused existing law and that seems entirely appropriate to me. Hopefully it gets through to the totally obnoxious man that his conspiracy theory  had no basis in fact and that he should reconsider his views. However sadly some people become stubbornly attached to their views and unable to move on. 


    Regarding hate speech. The New Zealand did consider hate speech law. The problem was the governmnet defining "hate" and defining which things should be included and gender, race, religion and disabled people were considered. There was a lot of public pushback that for example you would no longer be able to criticise religion or discuss gender issues even if done politely.  So while I intensely dislike bigotry and so forth  I lean towards free speech with just a few minimal and focused restrictions. Yes if you had strong censorship smart people can find a way of discussing whatever they want through careful language but I believe most people would just give up participating out of fear and this is to everyones detriment.


    We have to be able to discuss things, fairly easily and openly and without fearing that just about anything we say could get us sued, convicted, fined or thrown off websites or comments deleted,  so restrictions need to be fairly minimal.

    Rob, I mixed you w Bob again! So sorry. Thats two!


    NIgelj,


    If they open some ability for all to sue if false statements, liable or defamation is there, then the market will take care of this. That would be better than even more regs.


    This site and folks do fine, and this is a hard place to manage. I have spoken of tolerance but Im not sure how I would hold up here, every time I mean.


    I watch old Johnny Carson reruns and they were not allowed to say the name of a competing network if they needed to ID a show elsewhere. I am sure I will also evolve and there are more than several levels of censorship, some I agree with. Such as business competition. But not in other locates.


    Best again, D

    Thanks for the comments. I get where you are coming from.


    One clarification. I didnt mean that this website specifically deletes comments and I wasn't being critical of them for doing that. I was just speaking generally.


    This websites moderation policy actually seems generally quite well considered to me. Comments are deleted if they ramble off topic, make wild claims without reference to scientific literature or that just get repetitive.  People only have to obey a few simple rules to get their opinion published. Some people just resist this then get all agitated. They are either arrogant or just not very bright.


    The point is this website doesnt delete opinions just because it doesnt agree with them. People get a generally fair go. So the level of 'censorship' on this website  is acceptable,  but I would say its right at the upper limit of whats appropriate.


    Yes Fox News is absolutely selective and biased. However this is not an excuse for us to do ever do the same. We should always strive to be objective. If there is a bias or adherence to some ideology it should be advertised: The economist.com does this nicely in its mission statement but I cant find thething now to copy and paste. It was something along the lines that they lean centre right economically and towards free trade  but are not adverse to governments having some involvement in the economy. And that they lean liberal socially. So readers know their philosophical leaning


    Yes we all get that there have to be some limits on free speech. Its entirely about where one draws the line in the sand. Governments impose some limits on free speech. I have no problem with that in principle and generally they are fairly minimal in western countries and that is to my preference.


    The NZ governmnet goes slightly beyond some countries because it has laws against racist speech and this makes sense to me for reasons stated up thread. Its been considering hate speech law but has given up for now, because its so difficult to define hate speech and there has been a lot of push back against potentially suppressing discussion because almost anything could be labelled hate. This seems like a valid concern to me.


    But its not only governments that can limit free speech. My main concern is what websites do and I lean towards fairly minimal moderation. You and Electic seem to lean towards quite strong censorship on websites. Six months ago my views were virtually identical to Electics on this. So similar its quite startling. Now I just wonder if strong censorship  might do more harm than good. I think the trigger was our governmnets attempts to bring in hate speech laws. It just doesnt seem possible to define adequately or practically viable and is too likely to suppress opinion, and just too Orwellian for me.


    I'm sure you and Eclectic would do a good fair minded job of moderation of such issues,  but its other people I worry about.


    So back to Twitter. It is not entirely clear what Musk is up to yet. However it appears he leans strongly towards libertarian values and free speech and against censorship, and it appears he is not going to be banning people or deleting comments unless they are inciting criminal activity or are just  being extremely verbally abusive and bullying. 


    One problem is there isnt another website offering a similar service to Twitter to my knowledge. Given I have my doubts about hate speech laws, and the lack of alternatives to Twitter,  I dont think this website should feel it has to abandon Twitter at this stage. FWIW.

    Nigelj @67 :


    Agreed.  Woke is nowadays an ugly term.   AFAICT it started as a somewhat light-hearted label, and then was seized by the non-woke and used as an all-purpose bludgeon in the identity-politics game.   The word has now become almost meaningless, other than distinguishing "them" from "us the good people".


    Sad when any meaningful word loses its meaning.  For example, in the USA the word "socialist" has no actual meaning for 90% of the population.  It is just a bludgeon used by many politicians.   Impossible to have a genuine discussion using that word, because the hearer automatically short-circuits his brain into "evil enemy ... evil enemy ... Spawn of Satan ... etc."   [Shades of "1984" language-shaping, eh!]    And yet the same hearer is happy to accept his farm subsidy or his Social Security cheque or his Medicare-ized hospital treatment, etcetera.


    Possibly, in time, the term Woke can be rehabilitated into something light-hearted and useful . . . by overusing the word and applying it to everything in sight (and especially to right-wing attitudes & activities).   By making it so greasy that it can't be grasped as a weapon.


     


    Back on topic ~ for Twitter etcetera I would prefer to be over-censored than under-censored.   Much less harm done, that way.   Those who wish to have an intelligent public conversation, can find indirect ways & allusions to discuss issues (by treading a tad carefully).   And the truly anti-social citizens will always continue to use their echochambers & dark spaces  ~  but they won't get condoned or "normalized" in the public gaze.


    To some extent, laws follow public sentiment.  But the converse also applies  ~ and George Bernard Shaw points out how laws can shape public sentiment, over time.   Useful, to start with good laws.  (Think: the Anti-Slavery laws).
