       By CO2 not coming from humans, I meant respiration. This is essentially a neutral cycle. Additional CO2 is coming mainly from fossil fuel burning.

       Zippi @62, Spencer is not simply an intelligent meterologist. He is a principal research scientist at the University of Alabama in Huntsville, and the U.S. Science Team leader for the Advanced Microwave Scanning Radiometer (AMSR-E) on NASA's Aqua satellite. According to wikipedia.

       He is also a creationist who believes humans are too insignificant in gods creation to cause climate change.  Again, you can read this on his wikipedia profile page.  

       "I also know where emissions come from," 

       Well you apparently don't. I can tell you where they don't come from: The oceans, humans,  and volcanoes and theres plenty of information on this in the "most used climate myths" part of this website.

       I don't see anyone claiming that it is the 'weight' of CO2 that is critical. Its extra quantity in ppm added to atmosphere as in the keeling curve.

       However a certain weight is added to the atmosphere and this is additional weight. This is obviously a fact.

       Oxygen is important and must be considered. It's the two oxygen atoms that allow the CO2 molecule to basically wobble around and this quantum property is what enables it to absorb energy. As in this graphic. This is mainly why CO2 absorbs heat (technically IR radiation) and O2 doesn't.

       I know what Spencer says. He's an intelligent meteorologist.

       Those "big numbers" are important. That's why we don't have the "runaway effect". 

       I also know where emissions come from, but a disingenuous scientist like yourself can't add 44 grams of CO2 to Earth's atmosphere when the atmosphere originally maintained the 2 oxygen atoms that were added through combustion. Let's reduce the added "tonnage" to the atmosphere by 73% (0.7272727272727) and stick to the additional carbon atom that married a couple of oxygen atoms through combustion. OK?

       @ Moderator

       Since the earth surface is 790,854,451,200,000,000 million square inches and the weight of one square inch of atmosphere at sea level weighs 14.7lbs. Then the total weight of the atmosphere is 1,162,556,043,264,000,000,000 lbs. Which I think is 1 sextillion lbs. since there are 2000lbs in a ton then the earth’s atmosphere weight in tons is 5,812,780,216,320,000 tons so the closest answer would be about 6 quadrillion tons "if" the Earth was flat.
       Obviously the entire earth is not flat and other factors take that weight downwards.

       In all actuality combustion only adds 12 grams of weight per molecule of CO2 to the atmosphere. The additional oxygen in CO2 was used from existing oxygen in our atmosphere. You can't add what was already there as far as "tons added". That's another scientific misnomer.

       If you want to add the weight of additional carbon, then that's fine, but when you are scientifically disingenuous and add the whole as an overall "addition" to the atmosphere, then you surely need to be called out.

       The 2 oxygen atoms will eventually be released back into the atmosphere away from the carbon through either photosynthesis or some other process. It's called the "carbon cycle" simply because oxygen (O2) is the transporter.

       Oh big numbers!  Anyone can post superfluous or irrelevant big numbers and long words pulled out of a hat like the rabbit. 

       As Moderator says, CO2 emissions are coming from fossil fuels etc. It's one of those things proven beyond doubt now.

       Notice how none of the serious qualified sceptics like Spencer deny this, only the armchair eccentrics. Its embarassing watching people deny the obvious, and just shows their desperation and ignorance.

       Regarding this denialist slogan "we had a cold winter, or snow storm, so global warming is a myth". (or similar statements) I'm sure people must realise it's a ridiculous statement, nobody is that dumb are they?

       It's got to be either deliberate ignorance, or game playing to annoy people and bait them. Be careful guys: climate change is not a time for playing silly games, and provoking people.

       Thanks. I was working through this thread when I saw the ongoing discussion with Gail and could not resist putting in my two cents.

       Bob Loblaw @ 349

       
       I appreciate that the future increases may not be linear but it seems to me to be a good baseline with which to start. As soon as you extrapolate beyond a linear analysis my sense is that your are into the validity of the models. I personally do not have sufficient science background to understand the issues regarding their ability to predict the future.

       I was hoping to see a Red Team Blue Team debate this but I do not think that is going to happen given the information I passed on from Climatewire regarding the Trump administration having second thoughts about same.

       Earlier on in this thread there was a fascinating high level exchange going on between riccardo and PaulK who both clearly are physicists which unfortunately petered out.  But it was fascinating to see these two go head to head.  Although I could not understand the physics I did see the two of them being very honest with each other and I could get a sense of what was happening.  It is this "give and take" that would be so fascinating to watch on a Red Team Blue Team discussion.

       Thank you John and the Team for another year of enlightening about CS.

       As other commenter (nigelj) has put on other weekly thread, this year will go to history as the "dumbest year" (so far) in politics. While agreeing, I also note that we're not over through dark ages yet: t-man the clown can still conceive sillier, more outragous ideas in next 3 years in office, if Congress does not impeach him.

       In that disgusting reality, SkS shines the bright light of knowledge & hope. May next year be better and science and reason wins!

       Fake news is a threat to humanity, but scientists may have a solution
       

       There may be some objection to my comment point about "...the need for some people to be removed from the competition, particularly from positions of influence and leadership, as soon as the evidence of their desire for unhelpful actions is clear."

       Any business that fails to do that has no real future. Failing to correct that type of behaviour may create an appearance of value in the short-term, but eventually the damaging reality will be undeniable. Of course, many harmful gamblers only need the short-term to gather up significant unjustified benefit and hide it and themselves away, with repeated denial that they did anything wrong being their last/main line of defense.

       The 'climate issue' is based upon the Earth's ability to receive an additional 616 billion tons of natural (from nature) CO2 (40% increase from pre-industrial levels) into a 5.5 quadrillion ton and continuously moving atmospheric system that already had a naturally induced 1.54 trillion tons of CO2 working in continuous circulation with a receptive biosphere and receptive 1,450,000,000,000,000,000 ton hydrosphere (oceans).

       Moderator Response:

       [TD] More than 100% of at least the past 50 years' (probably decades more than that) increase in atmospheric CO2 is from anthropocentric causes. Read the relevant post's Basic tabbed pane, then watch the video, then read the Intermediate tabbed pane. There are several lines of evidence, but really the algebraic one (mass balance) is sufficient and airtight. If you want clarification, more evidence, or want to argue, do so on that post, not this one.

       Fake news is a threat to humanity, but scientists may have a solution
       

       This article got me thinking ... Then the comments got me thinking some more ... then the challenge of writing a reduced presentation of my thoughts ... made more challenging by my understanding that shortening a presentation to be a punchier marketing sales pitch piece by using shorter statements and emotive labels rather than providing dispassionate fuller explanations will lead to arguments about interpretation rather than discussion of the real problem that was trying to be pointed out ... so I gave up on trying to limit what I wrote ... hope the intent/point is clear ...

       Key Words/Thoughts/Considerations: Alignment - Common Increased Awareness and Understanding; Good Objectives/Intent; Sustainable Change - Improvement/Progress; Future of Humanity; Competition to Win; The Good, The Bad, Help and Harm.

       The 'technocognition' proposal can be helpful. But it's success and sustainability will require understanding and acceptance that it is guided by, and aligned with, Global Sustainable Public Good Objectives. The Sustainable Development Goals are an excellent compilation of Good Objectives. They include Climate Action. And, like the climate science basis for the Climate Action Goals, all of the identified goals have an extensive and robust basis, making them open to potential change but only for Good Reason (like climate science, everyone cannot be free to have their own opinion about these goals).

       The Key Point: The discussions and disputes regarding this article (on this site and at the Guardian site) expose a lack of alignment regarding what the real problem is. The propensity for people to seek validation for understandably harmful unjustified beliefs is caused by a more fundamental problem. The fundamental problem is the result of the combination of 'competition to Win that is not governed by alignment on a Good Objective measure of what is allowed/forbidden in the competition', with the powerful alluring dogma that 'everyone freer to believe what they want and do as they please is the best/only way to develop good results', and leniency regarding misleading marketing and reporting. Without the filter/limits of a Governing Good Objective, all manner of unacceptable ways of marketing and competing can, and will, develop and Win for as long as they can be gotten away with, with undeniably damaging results.

       Climate science has unwittingly exposed the need for some people to be removed from the competition, particularly from positions of influence and leadership, as soon as the evidence of their desire for unhelpful actions is clear. That means effectively neutralizing the impact of information providers in the system/competition for Good Reason, not just hoping that warnings about the incorrect presentations they have delivered will be effective. A 'mechanism' to catch every variation of presentation of misinformation would rely on the public acceptance that such a mechanism is 'justified/correct'. Such a mechanism could never flag a presentation that could be 'open to interpretation' because the first time it did so would be the fuel for the denial pushers/addicts to proclaim that the mechanism is biased/rigged 'Against Them'. Mind you, they would also believe that any information presentation contrary to their Private Interests is biased/rigged 'Against Them'. And they would be correct about the bias because their Private Interest must be commonly understood to deserve derision.

       The key is having alignment and common understanding regarding Helpful Public Objectives and Intentions, especially among the leaders/winners among humanity. There can be many divisive matters but the focus must remain on understanding how any 'side' is helpful/harmful. Helpful Conservatives can, and should, have healthy debates with Helpful Democrats. Correctly distinguishing the Helpful from the Harmful allows debate among leaders to be of value. That requires a common Good basis for that evaluation. That Common/Public Good basis for evaluation is what appears to be missing, leading to damaging rather than helpful divisive behaviour among competing leaders, leading to misleading marketing efforts that are powerful even though they are ultimately unsustainable (I support being divisive when it comes to helpful vs harmful. The harmful should be helped to change their minds, and not be free to influence things until they prove they have decided to be helpful).

       That leads to the appreciation that there can be Good and Bad in any action. There can be good and bad biased reporting (or conservatives, democrats, capitalist, communists, socialists, environmentalists, religious, ...). Good Biased Reporting is the acceptable/desirable kind of reporting. People with Private Interests that are contrary to The Global Public Good will focus on twisted claims/excuses like 'Bias is Bad (when it is against Them)' - Any Belief must be tolerated (unless it is not liked by Them)', rather than face the challenge of the differences that matter and make Their beliefs/opinions/desires (private interests) understandably unacceptable/unjustified.

       How do you communicate with those type of people to make them more aware and understanding? How do you educate them? How do you 'correct their thinking'? How do you 'Change their Minds'?

       Many people who are tempted to try to win by behaving less acceptably cannot be 'corrected' before they get a taste for winning that way. And once a person or group get a taste of winning by getting away with behaving less acceptably than 'the competition' it can be very difficult to 'fully correct their understandably damaging addiction'. The result is the competition spiralling downward as people compete to Win as unacceptably and harmfully as possible.

       The following warning from John Stuart Mill in “On Liberty” keeps coming to mind: “If society lets a considerable number of its members grow up mere children, incapable of being acted on by rational consideration of distant motives, society has itself to blame for the consequences.”

       The focus needs to be understanding the Fundamental Problem and being aligned on a Good Objective for the 'fix'. That will develop a sustainable solution rather than just creating the temporary impression that things have been fixed for good (with some people believing/complaining that the Fix is Unjustifiably Against Them).

       I have many Back-up and related thoughts but choose to only include the following:
       As an engineer with an MBA whenever I am presented with an existing item that 'appears, or is claimed, to need to be fixed or corrected' my first step is to ensure I identify/understand the fundamental basis of the problem (being as aware as possible and understanding as much as possible). I also make sure that any correction is consistent with the overall guiding objective of engineering to protect the general population (Others) and the environment (today and into the future), from the potential negative consequences of what a pursuer of Private Interest may try to get away with. That objective is well aligned with the Sustainable Development Goals. Unfortunately many engineering actions have that objective diminished by 'being balanced with Private Interests that are contrary to that objective (less safe, more harmful). My MBA training helped me understand and witness how motivated many classmates pursuing an MBA were to Win their competition for Private Interests any way they could get away with.

       Being guided by that awareness and understanding has led me to disappoint many clients/customers who have identified that their desire is 'to get something done quicker or cheaper'. Admittedly, developing the most advantageous solution to a challenge is an objective of engineering. But responsible considerate engineering (moral/ethical engineering) always has to severely limit the potential for negative Public/Environmental consequences (at the expense of the customer). When I point out the time and cost required to ensure the Quality of the engineered result there is often a claim that my job is to make them happy because 'the customer is always correct'. My response has been to pursue 'correcting the customer' to make sure the customer is actually correct. That often requires support from superiors who must be aligned with the understanding of how everyone is protected when such customers get corrected.

       The bottom line is: If the fundamental cause of the problem is not identified, or if the 'fix' is not aligned with protecting the Public/Environment into the future, then any 'fix' will not be sustainable. It will only appear to repair what appeared to be broken. There will likely be future failure because the real problem was not identified and corrected.

       Fake news is a threat to humanity, but scientists may have a solution
       

       I agree conspiracy theory thinking allows people to reject uncomfortable information. This is partly because you can't really disprove some conspiracy, so its an easy escape. The entire climate denial movement appears fixated on conspiracy theories.

       Conspiracy theory ideation is largely childish. Read scientific and hard evidence on so called conspiracies, and you will see most of them are nonsense and just escapism and lazy thinking (but fun to read about, I lap them up out of curiosity)

       But there is of course a grain of truth sometimes. Companies are sometimes caught colluding to fix prices, and end up in trouble with the authorities. But this has to be proven!

       Are governments all colluding to create a global warming scare? It doesn't make sense to me, because the costs of climate change on governments in providing all this renewable energy etc would be far larger than any benefits from some increase in their powers, which would at best be some carbon tax and so on. This is not some huge enhancement of powers, especially as the proposals are for tax and dividend schemes.

       And IMO such a giant climate conspiracy would have leaked out by now if it was true, and is about as likely as 911 being an "inside job".

       US government climate report looks at how the oceans are buffering climate change
       

       Zippi62 @7

       "Why do we look for deep ocean heat today, when our current ocean surface warming trend is less than what it was between 1911 and 1941?"

       Because the warming since the 1980's is significant and outside the boundaries of natural variation, and evidence shows its driven by CO2 and not natural factors.

       The warming period between 1911- 1941 was only 30 years long, so still just within the boundaries of natural variation, so not hugely significant. It was due to a combination of CO2 emissions, high solar activity, and low volcanic activity. The period was a coincidence of multiple factors all at one time, so very non typical.

       "the vested interest of a funder can corrupt the science"

       That something is possible says nothing about the likelihood. It is possible that an undetected asteroid will hit the earth and destroy life as we know it before I will get a chance to ring in the New Year tonight. It's not worth changing my plans for that possibility, though.

       Gail's repeated assertions basically amount to claiming that all the science is made up to get money, and every scientist that publishes on climate change and supports the idea that it is happening, humans are causing the bulk of recent warming, and it will get a lot worse if we continue to burn fossil fuels at current rates, are all part of a conspiracy to hide the truth. It basically lets her reject anything she doesn't like.

       NorrisM: "Everyone agrees that additional levels of CO2 are causing global warming."

       Everyone? I constantly see people deny that there is any warming at all, and constantly see people deny that CO2 can cause any warming.

       How much of the current warming is due to rising CO2 is an attribution question, and the IPCC has stated that the best estimate is all of it.

       As for how much warming is predicted in the future, under different scenarios, and how models fit into the question, please take that to the Models are Unreliable thread,

       ...and the future predictions are not a linear extrapolation of recent trends. That is not a good way of doing the analysis.

       Gail @33

       "The overarching point is that the vested interest of a funder can corrupt the science to its own needs."

       Yes fair enough.  However I dont see governments directing the science in any significant way. If you are very paranoid you might believe they use the climate scare to increase their powers, so look to somehow exaggerate the science, but we see many centre right anti tax parties taking climate change seriously, presumably because they see the risk factor ( as already pointed out to you above).

       If anything, and I have to say this again hoping you see the point, governments would probably prefer the climate problem to just go away. If they want to "increase their powers" there are much simpler and more nefarious ways of doing this! 

       In fact I would suggest that if government does inject a bias into the science, it would be to 'downplay' the risks of climate change. It's commonsense! However I doubt they would be aggressive in doing this, or it may vary depending on the policial party of the day. Clearly The republican party dont like climate science.

       And we do actually have some anecdotal evidence leaking out that government officials who sign off the IPCC reports have tried to have the risks of dangerous climate change and levels of certainty of climate change downplayed.

       Of course there is the allegation of whether scientists inflate the risk of climate change to get governments worried so they then fund research. Just remember scientists are employed as a matter of course to do science on all sorts of issues that pose no threat, like studying beetles, they dont have to scaremonger to get work. Scientists are also trained to be restrained and objective. They may of course say climate change is serious and needs study: But Gail it is clearly a serious issue so this is only stating the obvious.

       In comparison, the fossil fuel industry have strong interests in business as usual, and are likely to go shopping for scientists who have a sceptical point of view. Once employed, they may become even more biased towards a sceptical view out of fear of losing their contracts. 

       Anyway as pointed out by others funding comes from both governments, companies and other sources, and this is very healthy balance that ensures we get good information overall. But the fossil fuel funded sceptical leaning studies have been unconvicing - for decades now. That should tell you something.

       compx2,

       I think time has caught up with your comment "Let's just say Ice overall is growing in Antarctica, okay?" which is now twenty months out of date.

       Overall, the Antarctic ice cap was certainly not "growing" ice-wise over the period 2002-16. (The Zwally theorising mentioned in the OP update is an interesting theory but nothing more.) And the Antarctic Sea Ice had been showing a slow rise in SIE over the satellite record 1978-2010 and then did show a dramatic upward wobble to early 2016. But since then, as the comment @463 pointed out, the drama has been in the opposite direction and now SIE continues lower than at any time earlier than 2016.

       "Makes one wonder where "biased" polsters draw their lines. Most conservative thinkers I know avoid biased pollsters"

       This is too anecdotal, and it is highly improbable that conservatives simply don't do polls.

       "Millions of global warming/climate change protesters protesting in big cities where the environment can barely be be studied by those who protest. They have to depend on scientists to be honest and unbiased in their evaluations of each and every research study they perform using taxpayer dollars. "

       Partly true, but you don't need to be a scientist to understand that we are altering the climate. All you need is a reasonable education. The evidence is pretty basic and overwhelming.

       One data set or research paper might be unreliable, but we have numerous data sets and research papers,so its slander to suggest they are all somehow intellectually dishonest. Every paper discusses areas of certainty, and issues where uncertainty remains, so it's pretty transparent.

       "Most big government environmental scientists have a bias IMO, otherwise they wouldn't worry about who becomes POTUS."

       Not interested in your opinion, unless you can back it up with some information. Any sane person would worry about a president that tries to remove data from websites, and has scientifically illiterate views.

       "George H.W. Bush Sr., Bill Clinto, George Bush Jr., and Barack Obama were all "globalists". (Remember George Sr.'s 'new world order' statement?)"

       Irrelevant to the climate issue. You are also paranoid about globalism. The world has been globalising ever since we first started trading with each other. Imo the challenge is to get the global rules on a fair basis, and the balance of power right between nation states and larger global authorities, so that we avoid potential for abuse of power.

       "Let us not forget where the UN IPCC came from and how it has progressed over the past 30 years and what the United Nations' ultimate goal is. Globalism. Un-elected government officials (they are appointed) being handed billions of dollars every year for climate research projects and advisory boards."

       The Un doesn't primarily fund climate reseach, nation states do.

       "The corn-belt of the U.S. does lots of climate research. Farmers are a good source for spotting "climate change indicators".

       Yes, and they say the climate is changing.

       "Purdue University did a survey aimed at Agricultural Extension educators, agricultural advisors, and farmers. Over 90% (1,560) of those surveyed mostly believed that either the environment and humans are 50/50 responsible (~33%)"

       What makes you think farmers have any special insight on science? Their educational levels tend to be rather average or below average. They also tend to be Republican supporters and the Republican Party is sceptical of climate science, unfortunately. That's not to say farmers are inferior to anyone else, they aren't - and we rely on farmers for our very survival.

       "Big city dwellers are easy to antagonize."

       Well you might be right about that. I dont know why, but I have some good guesses on it. But its not really that relevant to the climate issue.

       The "resistance" comes from those who feel that they can trust the "97% consensus" mantra. Populations in large cities like New York, Los Angeles, San Francisco, Chicago, Denver, Seattle, Portland, Washington, D.C., Detroit, Philadelphia, Baltimore, St. Louis, and Miami vote 75%+ 'democrat' and are the most likely places for demonstrations ("resistance"). It's easy to dupe those who can't verify scientific findings on their own. 99.9% of these people aren't scientists.

Bush Sr., Bill Clinto, George Bush Jr., and Barack Obama were all "globalists". (Remember George Sr.'s 'new world order' statement?)

       Let us not forget where the UN IPCC came from and how it has progressed over the past 30 years and what the United Nations' ultimate goal is. Globalism. Un-elected government officials (they are appointed) being handed billions of dollars every year for climate research projects and advisory boards.

       The corn-belt of the U.S. does lots of climate research. Farmers are a good source for spotting "climate change indicators".

       Purdue University did a survey aimed at Agricultural Extension educators, agricultural advisors, and farmers. Over 90% (1,560) of those surveyed mostly believed that either the environment and humans are 50/50 responsible (~33%), the climate has changedand is mostly natural (~29%) or their is insufficient evidence to know with any certainty that the climate is occuring or not (~28%). Less than 10% believe it is happening and is caused by human activities.

       It's easy to convince big city-dwelling populations. That's the only world they know. They generally can't understand how big the world really is.

       The 20 most populated areas in the U.S. (previous list of cities plus 6 other highly populated areas) take up less than 14,000 square miles of the 3,500,000+ square miles United States land area (0.04% of the total U.S. land area). (Hillary Clinton received 10 million more votes in these 20 most populated areas. She won the popular vote by less than 3 million)

       Big city dwellers are easy to antagonize. 

       If anything, Global Warming alarmism plays to those who don't have the luxury of exploring the world outside of their own city. They are the poorest of the poor.

       Good luck in your celebration! The science isn't as 'cut-and-dry' as is portrayed by those who seem to love antagonizing people into a "resistance" they don't understand.

       they included papers that did not quantify the Anthropogenic contribution to warming.

        

       and when you check the abstracts of for example endorsement level 3, you find that they did count unquantified abstracts as supporting, thus the claim in the intro of the study is false.

But instead of your subjective, reference-free and incorrect assertions of the bank balance, climatologists have done the accounting quantitatively, with references to source data and methods,  including uncertainties, and from multiple types of data, data sources, and methods. The most recent I've found is a reference I already pointed you to, which you seem to have totally ignored: Trenberth et al. (2016).

       That was why I was asking for some estimate of warming from two periods, 1950 and 1975. Perhaps the two periods should be from 1950 and 1970.

       I agree that the rate from 1950 at least would be more relevant.  It would be interesting to look at 1970 but we then get into shorter periods which themselves have problems.

       I appreciate my question on models might be getting "off topic" but these questions on the rate of temperature increase certainly relate to "empirical evidence".

       Perhaps this is just impossible to do because of other factors such as the aerosols, volcanoes, ENSO etc.  I think I read somewhere on this website that ocean temperature increases are a better measure.  Surely there are some papers on this because it is such an obvious question.

       Are there studies to show accelerating ocean temperatures?

       Moderator Response:

       [TD] See the Nuccitelli 2012 graph to see that ocean heat content dwarfs that of air, land, and ice. Then for a more up to date graph of ocean heat content, and one in which the acceleration is obvious, see John Abraham's post, and for details read the article that John's post summarizes.

       Antarctica is gaining ice
       

       It sounds to the outsider as though it is very important to you guys to say that the addition of ice in Antarctica is NOT due to global warming, a separate issue related to Ozone (are humans responsible for the Ozone hole?).  But the loss of ice is due to global warming.
       
       Seems to me addition of ice is a simple thing to say, and that attributing it to something else is kind of like saying this ice is different from that ice, that some ice counts toward the ice in Antarctica and some doesn't count.
       
       And you sound awefully sure about that Ozone hole,  Where are the references to the studies that prove lack of Ozone is the problem?  Well, is there a problem that Ozone ice is messing up something in Antarctica?  Should be plug the Ozone hole?
       
       Let's just say Ice overall is growing in Antarctica, okay?

       Fake news is a threat to humanity, but scientists may have a solution
       

       @Gail 33

       The problem is not just that you are biased against (climate) scientists but you give the impression you view the world of funding in a very simplistic, cynical and black and white way. 

       How do you think scientists should be funded? By government or industry? Obviously the answer is both because you need independence from industry but also industry genuinely wants answers to questions, so they sometimes employ scientists directly or commission research. Naturally, ultimately, these are just people with various levels of integrity as is reflected anywhere.

       Scientists, on the whole, take a pride in their objectivity and value the integrity of science and truth. This does not mean none of them cannot be corrupted by money but that is rare. (Hence the very few contrarian scientists perhaps?). More the problem is industry taking research results and then spinning the results to over-emphasise small effects or ignore poor results. This can be ameliorated by good communication from scientists but they tend not to have budgets for this. 

       When scientists accept funding there are always contracts that protect the integrity of the science and bolster the independence of the scientists. This can get quite messy when it comes to interpretation and control of results. But on the whole there is quite a distinct gap between the scientists and the industry.

       Your view that everything is just all one-way to the bad is just unrealistic.

       Skepticism about climate science isn't over the basic notion of AGW,  which is widely accepted;   sooner or later there must surely be a problem, yes.   It's about whether the science truly is settled as regards How Much Warming How Soon - ie the claimed high certainty of an  imminent catastrophe (CAGW).  And also more general skepticism over  objectivity.

       Otherwise you should already be aware that one important aspect of the rating done for the paper (and actually mentioned in it) is that any wording minimising anthropogenic warming would have made the abstract go into one of the rejection categories, thus ruling out the inclusion of "human activity cause some warming" in categories 1 -3.

       Gail @31 , your arguing is getting even more confused.

       You are comparing apples and oranges.   Tobacco-funded research was "looking for an escape clause" — they wanted to find "negatives" or at least some counter-arguments against the scientific consensus position.

       Government-funded climate research [done by agencies, institutions, and hundreds of independent universities] is not angled toward an escape clause — every genuine climate scientist knows there is no escape clause and there is no counter-argument against AGW.   If there were a valid counter-argument against AGW, then the handful of "contrarian scientists" [richly backed by Fossil Fuel industry funds] would have discovered & publicized it long before now.   And indeed, the contrarians don't have a clue : they only have various hypotheses which have already been proven false (and their "hypotheses" are mutually contradictory and have zero evidence backing them).

       Gail, you are comparing apples and oranges there . . . and so your conclusions are invalid.  Invalid and worthless.

       Gail, it is high time you started to educate yourself about science.

       CO2 limits won't cool the planet
       

       Aaron Davis @27,

       I assume you have not carried out even the most simplistic of calculations to support you assertion "So, if anything albedo and CO2 combination, should overstate the seasonal effect over CO2 alone." If you had, you would have noticed that, while the impact of surface albedo will accentuate your elusive little CO2 effect, if you calculated it properly even for that pair of two-month-periods, you would see that during the periods and zones in question, insolation & albedo are far bigger effects than your teeny weeny dip in CO2. The insolation works against the CO2 effect and is about 100 x bigger (+13Wm^-2 compared with -0.14Wm^-2). The Surface Albedo effect is bigger still being about 300 x teeny weeny CO2 effect but additional to it. So the combination of Insolation and Surface Albedo sits 200 x bigger than the teeny weeny effect you attempt to measure (-27Wm^-2). Of course the atmospheric albedo is still to be accounted as has the imbalances in preceeding months. And there is still a whole pile of other factors beyond solar energy input.

       I must stress that the reason your teeny weeny CO2 effect is so insignificant is not because CO2 forcing is insignificant or even that 15ppm CO2 is entirely insignificant. It is because the 15ppm CO2 dip you attempt to measure is only operating for a couple of months before you attempt to measure its impact.

       The 9e18j value you ask about reflects the size of the zone impacted by the dip and its accumulative impact by the time of your temperature measurement. It is not a global figure. Why would it be? (The annual global forcing from -15ppm ΔCO2 would today amount to 2,250e18j, an effect that is far from insignificant.) That you apparently see some notion mirroring your own denialism in my comments is entirely illusory on your part.

       He who pays the reseacher calls the tune.  No sensible layman would trust tobacco-funded research into smoking would they ?     No,  because the motives of a science's funder can easily skew and disguise results to advance the funder's vested interest,  cleverly highlighting or hiding various aspects as needed.
       Moderators - Yes, your rule is that political comments are not allowed. But, as it happens, most climate science is politically funded.  So you have thus ruled out any fundamental discussion of the actual practice of climate science, its motives and adherence to the scientific method.   
       I  think that is Unskeptical Science, and urge you to reconsider.

       97% consensus on human-caused global warming has been disproven
       

       "We examined a large sample of the scientific literature on global CC, published over a 21 year period, in order to determine the level of scientific consensus that human activity is very likely causing most of the current GW (anthropogenic global warming, or AGW)."

       no you do not determine that level. because according to you data, there would have been a 87% consensus and not 97%.

        

       because you then change the consensus position to include unquantified statements.

        

       "To simplify the analysis, ratings were consolidated into three groups: endorsements (including implicit and explicit; categories 1–3 in table 2)"

        

       so people, carefull when you use that study as a source, the study shows that 97% of published studies state that human activity cause some warming.

        

       the paper does not show that 97% of the scientific literature on climate change support the conclusion that human activity cause MOST of the warming since mid 20th century, as is falsely claimed in the paper.

       how did this pass peer review?

       There's no empirical evidence
       

       Bob Loblaw @ 343

       Everyone agrees that additional levels of CO2 are causing global warming.  The question always comes down to how much warming.

       So does this not again bring us back to how good the GCMs are at predicting what impact this increased CO2 will have on future temperatures, even assuming that all of the observed warming since 1970 is attributable to CO2 emissions? 

       The models predict that we are not going to make a 2C limit for the period from 1870 to 2100 without serious cuts in CO2 well before that time.   

       But if you look at the "ballpark" .8C increase in the last 150 years that works out to around .05C per decade.  At this rate, 100 years from now (not 1870) we will add a further .5C representing a total of 1.3C since 1870.

       So we have to go back to the climate models to get to the 4-6C increases which are in the IPCC Fifth Assessment.  I may have these numbers wrong but you get my point.

       Perhaps someone can provide me with a calculation of the observed decadal increase from 1950 onwards, or, for that matter, even from 1975 to date.  

       Moderator Response:

       [TD] It is very clear that warming has accelerated over the last 150 years. Right off the bat, you must account for the pause in warming between about 1940 and 1970, which was due to huge dumping of reflective aerosols into the atmosphere. Ignoring that by averaging from 1850 onward seriously reduces the temperature increase rate estimate so it is unrepresentative of warming before that dumping and since that dumping was drastically reduced.

       Video: How not to panic about Global Warming
       

       Do the AGW supporting political celebrities actually believe what they are preaching?

       By now, most of us are familiar with the lavish, jet-setting lifestyles of the super rich politians who are pushing the agenda of the AGW (Anthropogenic Global Warming) community. These include both Clintons, Al Gore, and Barack Obama. While telling us "We the People" that we must reduce our carbon emissions or all kinds of catastrophies will happen, they seem to have no problem whatsoever in bouncing around the world (for both business aned pleasure) in their private jets or Air Force One. Most of us would call that hypocrisy on steroids, and I certainly would not argue that point, but there is another aspect to this that I find even more disturbing. These political celebs know full well that their money and influence won't save them from the disasters they describe, yet their personal lifestyles seem to indicate no concern at all. This leaves open the question of whether they personally believe in AGW, or if they know something the rest of us don't, and realize this threat is fictitious.

       Along these lines, there is another point that should be addressed. Back in the early 1990s, the Cold War ended along with the jobs of thousands upon thousands of defense scientists. By then, global warming was already considered to be a serious threat. These displaced scientists could have been put to work at better understanding the climate change situation and finding solutions, possibly in terms of cleaner burning fuels or more efficient engines, motors, and generators. But this didn't happen. Instead, the "peace dividend" went into helping the former Soviet scientists, bailing out failed financial institutions, and getting involved in every skirmish in the Middle East. Most of the high-profile politicians involved in making these decisions were also on the AGW bandwagon. What baffles me is that they continued with that "business as usual" attitude even though the lives and well-being of themselves and their own families were in as much danger from AGW as everyone else's. So what happened? Did they simply not care or did they realize the AGW threat was non-existent?

       The best way to not panic about global warming is to recognize that the very political celebrities that are promoting it are also the ones who, by their actions, seem the least worried about it. These include both Clintons, Al Gore, and Barack Obama. While telling us "We the People" that we must reduce our carbon emissions or all kinds of catastrophies will happen, they seem to have no problem whatsoever in keeping their "fuelish" lifestyle by bouncing around the world (for both business aned pleasure) in their private jets or Air Force One. Most of us would call that hypocrisy on steroids, but there is another aspect to this that I find even more disturbing. These political celebs know full well that their money and influence won't save them from the disasters they describe, yet their personal and professional lifestyles seem to indicate no concern at all.

       During the early 1990s, a period often remembered as the "end of the cold war" thousands of defense scientists lost their jobs, including me. At the time, AGW was already considered a threat by many, and the IPCC warned of various disasters occurring if we don't reduce our coarbon emissions by the year 2000. At this point, truly concerned AGW believing politians would have helped direct the "peace dividend" funds (ie. savings resulting from the defense cutbacks) to rehire at least some of these former defense scientists so that they could help find solutions or mitigate the coming crisis. This did not happen, however. Instead, the "peace dividend" went into helping the former Soviet scientists, bailing out failed financial institutions, and getting involved in every skirmish in the Middle East. Most of the high-profile politicians involved in making these decisions were also on the AGW bandwagon. What baffles me is that they continued with that "business as usual" attitude even though the lives and well-being of themselves and their own families were in as much danger from AGW as everyone else's. So what happened? Did they simply not care or did they realize the AGW threat was non-existent?

       So, as I see it, if the AGW celebs aren't worried about it, why should I be?

       Having worked in government research over two+ decades, I can definitely say that the times when I have felt that research outcomes were being suppressed if they did not meet the governing party's political agenda, it was when the political agenda was rejecting climate science, not the other way around.

       There's no empirical evidence
       

       To inject an analogy into all this earth energy balance discussion:

       Let's assume I keep all my money in a piggy bank. Everything I receive gets placed in the piggy bank, and all my expense are paid out of the piggy bank.

       I want to know if I am gaining or losing money over time. There are two ways to figure this out:

       1. Track every transaction that adds money to or takes money out of the piggy bank, and add them up to see what the ultimate change is.
       2. Count the contents of the piggy bank at the start and end of the month, and see if the total is different.

       If accurate, both methods will come up with the same result. If either method is error-prone, differences will occur within the margins of error.

       In the climate system, the earth-atmosphere as a whole is the energy piggy bank. The ocean is the largest energy store. The only way to add or remove energy from the earth-atmosphere piggy bank is through radiative transfer with space. The sun provides the input, and the earth emits IR radiation.

       We can track the imblance in two ways:

       1. Measure the radiation input and output, using satellites, and add everything up over time to determine the imbalance.
       2. Pick a start and end time, and measure the temperature changes and heat content of the oceans and atmosphere.

       Climatologists are smart. They are doing both. The first shows fingerprints of increased CO2 in the spectral distribution. Error sources in the absolute readings make an exact determination of the imbalance very difficult. The second unequivolcally shows warming/heating. The imbalance must be a net positive addition of energy.

       The two methods agree within the margins of error. The combined evidence leaves little room for doubt that increased CO2 has led to a radiative imbalance that is warming the planet.

       From the eMail Bag: Carbon Isotopes, Part 2: The Delta Notation
       

       Skeptical Science asks that you review the comments policy. Thank you.

       How to demonstrate to a denier the power of small amounts of stuff.  Ask them if they will take .4g g of cyanide.   that is to body weight what CO2 is to the atmosphere, or 4 parts in 10,000.  

       Every year, literally tens of thousands of workers in various industries have exposure to and ingest cyanide, most commonly KCN and NaCN.  They do not die because the body can deal with and process it.  But to much in a short period of time will kill you.

       You can even purchase certain vegetables in the grocery which if not prepared properly or consumed in to large a quantity will kill you.  https://en.wikipedia.org/wiki/Cassava.

       So natural, abailable, and to much can damage you.   Just like to much CO2 can damage the current ecosystem which include us.  So, the next time  an AGW denier goes on and on about how harmless small amounts of anything are, just offer him some cyanide.

       There's no empirical evidence
       

       Phillippe, some of the papers in the reference list in this paper by Trenberth et al. might provide that answer, if you feel like digging through them.

       US government climate report looks at how the oceans are buffering climate change
       

       Of course the oceans are buffering climate change.

       Warming one gallon of atmosphere isn't the same as warming one gallon of ocean water. It doesn't take much to warm a gallon of air by 1C. 

       How much energy does it take to raise the temperature of 352,670,000,000,000,000,000 gallons of ocean water by 0.1C versus 321,003,271 cubic miles of atmosphere?
