Bob Loblaw at 05:03 AM on 2 February 2023The escalator rises again
That's a good read, Jim. It's always time-consuming to show the errors in what appear to be simple results by people of the ilk of Monckton.
As for predictions of when they'll come up with a "new" claim of "no warming since..."? We've had a few years of La Nina and we're due for a warm El Nino year, so I'm going to guess we'll see if coming soon.
I've posted the following graphic in the past, and I just checked the timing of the original. I created it in July 2016. By then it was obvious that 2016 was going to be a warm year. By then it was obvious that a warm year like 2016 was going to give start to a whole new "no warming since..." meme.
So, my prediction is that the next one will probably be "no warming since 2023..." or "no warming since 2024..." We know that the false skeptic's material will be updated by a simple search/replace like this one.

One Planet Only Forever at 01:51 AM on 2 February 2023Checklist: How to take advantage of brand-new clean energy tax credits
peppers,
When you investigate 'deregulation' keep the following understanding regarding for-profit in mind.
The objective of for-profit is maximiaing profit. It's objective is not:
- minimizing harm done
- maintaining and increasing the quality of servces and products
- maintaining and improving the conditions experienced by workers
- developing sustainable activity
And note that a 'business-minded' government, like the ones often elected in regions like California, can have similar objectives of maximizing the profit of for-profit activity which compromes their leadership actions to be more harmful and be less helpful to those needing assistance ... because that is popular, and popularity wins elections.
And an important point is understanding the ways that misleading marketing 'promoting positive perceptions like the greatness of for-profit' impedes learning about what is harmful and delays the development of popularity for being less harmful and more helpful to others.

Here is an update on the NPR reporting about the Colorado River Basin water problem I linked to @15.
KUNC report: "Federal pressure mounts as states attempt to break Colorado River standoff"
The States involved have not been able to agree to solve the problem. And it is implied in the reporting that some State leadership may be happier if they are able to 'blame the Feds for imposing restrictions'.
The full series of reports are available at the following link.

One Planet Only Forever at 03:50 AM on 1 February 20232023 SkS Weekly Climate Change & Global Warming News Roundup #4
Here is some newer news that raises a very important point regarding the ‘objectives of human actions today’. It is reporting 'new research', but relates to my comment @1.
NPR News Item “AI is predicting the world is likely to hit a key warming threshold in 10-12 years”
The important point is the unfortunate, and incorrect, ways that the Paris Agreement targets of 1.5 C and 2.0 C are discussed.
The common sense needs to be that it is harmfully incorrect to refer to the 1.5 C target as ‘potentially, or actually, dead’. That incorrect way of thinking about the targets would be likely to also make 2.0 C ‘dead’.
The required understanding is that, ideally, human action would keep global warming impacts below 1.5 C. If the powerful among the current generation is unwilling to make that happen, if the leadership actions taken indicate that 1.5 C will be exceeded, then the portion of the population most responsible for making the problem worse has to be required to pay today to start removal of CO2 from the atmosphere. And that ‘non-profitable action’ needs to be done with the least harmful of the currently developed technologies for doing that, not the least expensive. And any improvements that would further reduce the harm of those ‘removal operations already started’ would need to be implemented as modifications of existing operations, not just be part of new items built. And continued inaction to limit the harm done would trigger a larger 'penalty to do more 'now' to remove CO2.
The science has long been clear that limiting harm done requires human global warming impacts to be brought back below 1.5 C. That will require unprofitable actions that need to be as harmless as possible. It is almost certain that the only way that will happen, and most effectively happen, is if the most harmful portion of the current population, those who benefited most from the developed problem and those who are currently benefiting most from continuing to make the problem worse, will not give up their harmful desires ‘they have to pay now, and be required to fix the problem as harmlessly as possible’. That penalty mechanism is likely the only way to keep human impacts below 2.0 C and minimize the magnitude and duration of an overshoot of impact above 1.5 C without having 'the solutions be new unnecessarily harmful developments'.

nigelj at 06:04 AM on 31 January 2023Checklist: How to take advantage of brand-new clean energy tax credits
Peppers @9, while there are several hundred billion tons of uranium dissolved in sea water attempts to extract it have not been encouraging. It doesnt look like it will ever be economic.
There are trillions of tons of lithium dissolved in sea water and this has been extracted experimentally with quite good success. Its more costly than conventional lithium mining, but not prohibitely so and will probably be a good viable future source of lithium. Some geothermal bores are also rich in lithium and the potential quantities are enormous. This sort of thing is all easily googled so I'm not going to spend time posting links.
If we look back historically before the climate issue, the world has had a mixture of types of electricity generation, and many individual countries have had a mix of generation. New Zealand has had a mixture of hydro power, geothermal power, and coal fired plant. Since the warming problem we have closed most coal fired plants added gas fired plant and added wind power and a little bit of solar power. My point is while theres a tendency to want one singular power source thats perfect, it probably doesn't exist, and the future will also be a mixture of things including some limited nuclear power.

One Planet Only Forever at 01:17 AM on 31 January 2023Checklist: How to take advantage of brand-new clean energy tax credits
peppers @9,
Regarding "... why does California apply doubling electricity costs to cover State programs of exploring and implimenting alternative sources ..." including the context you present it in.
A major part of the higher California electricity cost appears to be the result of 'deregulation (shift to for-profit competition)'. That has been observed to result in higher costs in every state that deregulated their electricity supply. The higher cost is not the result of the chosen method of electricity generation. It is due to the way the 'competition system operates to maximize profit for the major electricity generators'.
Also, the lower cost way of operating the system created situations that, under extreme wind conditions, caused failures that sparked wild fires because the very dry vegetation was not far enough away from broken power-lines. So the new operating procedure is to cut back power transmission when strong winds will blow in areas with dry vegetation. It is impractical to keep vegetation far away from where broken transmission lines may reach.
But a part of the California electricity cost is covering the legal penalty for the wild fires caused by the for-profit competitive electrical system operation that was the result of the government decision to deregulate.
The government of California is not 'applying a doubling of cost'. The real costs of deregulation are emerging.
Regarding "They are not encouraging the healthiest sources of power at all, ..."
That appears to be a misunderstanding resulting from the perspective of 'cheaper is better'. When all the harmful impacts of the energy alternatives are thoroughly considered all of the fossil fuel options are very harmful compared to solar or wind or hydro. Note that harmfulness is not restricted to 'human health impacts' and it also includes 'risks of harm, not just immediately identifiable harms to people'.
A more important concern regarding the specific situation of lower income people being unable to afford the basic needs of a decent life is "Why does the socioeconomic-political system fail to ensure that everybody is able to live at least a basic decent life?" GDP has risen faster than population (globally, and in almost every region) and yet extreme poverty remains to different degrees in almost every region (the Social Democracies of Europe and some small island nations appear to be the possible exceptions). What is wrong with the developed socioeconomic-political systems? The problem is likely the popularity of the 'positives of potential personal benefit' keeping people from learning about what is harmful and how to be less harmful and more helpful to others. A lot of what has developed is harmful and unsustainable. The required changes of understanding and behaviour will shatter many 'powerful positive perceptions'.

peppers at 21:41 PM on 30 January 2023Checklist: How to take advantage of brand-new clean energy tax credits
Thanks for all the input. Ill go over all of this in time.
Micheal, California's 44M have 2.5 times the rate for electricity than Washington States 8M. Nothing amusing there.
Forever, with the sentiment that unhealthy fuels should carry higher costs to diminish theri use, why does California apply doubling electricity costs to cover State programs of exploring and implimenting alternative sources, among covering other programs of wildfires and subsidies to the poor? Of which these policies increase their poor. They are not encouraging the healthiest sources of power at all, and it is punitive in nature to the common working citizen, such as my renters.
I was too general on the nuclear. There is enough uranium in the sea for thousands of years, but it is impractical in many ways to imagine the increased accidents and security needed for thousands more reactors. maybe not all power, but a small reactor outside each city, like so many nuclear subs. They are claming huge strides in safety and reuse of all waste, etc.
Nigelj, no we should not bury our heads in the sand. Something must be done. But in lieu of finding a real actionable solution, punishing the populous to hope to reduce global emissions 7% (if we achieve cutting our use in half) from the US is a bit doomy. As another said, if we settle on that we do not pursue more strongly an actual working solution. For now we need a backup when night comes, or the wind dies or snowpack is slow that year. We can work to lower needing fossil fuel to 1/3 of the time is the hieght of these goals. They are not worth doing as I see it, just to do something.
And 7% is the amount of new consumers added to the world every year, as we passed 8B on November 22,2022, and will find 9B in 2037. Thats one a and a half times the California population added each year, spread across and increasing the energy use in every global area and zone. The US will add California's population again within 35 years.
My 3 year old's day school is packed and Im not going to consider that this is the problem. This is what many of these solutions are based in, that the peoples behaviors are the problem. They should suffer. I am not fatalistic; im interested in the pie in the sky, or the 'pennecillin' solution to be found that will address this. Its actually, in my opinion, the only way. I do not have a moments thought it will not be found.
I have also told I have been a landlord for decades and how do I have a 3 year old! Yes Ill be throwing him a ball at 18 from my walker!
Thanks all. Best D

One Planet Only Forever at 12:45 PM on 30 January 2023Checklist: How to take advantage of brand-new clean energy tax credits
Hi peppers,
In addition to the responses by nigelj and michael sweet, I would add that it is very common for people to believe that 'cheaper is better'. As an engineer I understand the importance of doing something as inexpensively as possible. But as an engineer I would also always limit the alternatives being considered to 'very safe options' for good reason. And as an engineer I have repaired many built items, or limited their use, or taken them out of service because it became known that they were not as safe as they should be.
A major problem today is the prevalence of the belief that marketplace competition naturally develops safe results and would promptly remove or correct harmful developments. The opposite is actually closer to the truth because 'more harmful is usually cheaper and easier'. And 'the positive of more profitable' makes it less likely that developed items will be corrected to be less harmful by the marketplace.
Without external governing to limit harm done (requiring things to be more expensive) the marketplace will 'naturally' produce more harmful results in both senses of 'more'. Developed items will 'naturally' be more harmful (as harmful as can be gotten away with for as long as possible). And if/when developments are deemed to be too harmful, the replacements are likely to just be 'more' harmful options.
That brings up the type of 'belief' you are concerned about. The alternatives implemented being 'more harmful'. Things can indeed be very harmful if the potential harm is not well investigated before the new way 'replaces' the option that is deemed to be 'too harmful'. But that means that using natural gas should have been much more expensive long ago. And it also means that nuclear generation should have been more expensive, and hydro power. Even solar and wind power should be more expensive to address the potential harmful impacts.
The bottom line is that 'reduced energy consumption' is the required correction. And the power generated for 'essential energy consumption' needs to be 'as harmless as possible', not 'the cheaper way'.
The promotion of, and focus on, the positives, like lower cost, can result in reduced investigation and consideration of the potential negatives. Even if negatives are known, the developed desire for the positives can cause people to ignore, dismiss or excuse the negatives. That 'desire for the promoted positives' can make people disagree with, distrust or dislike anyone trying to help others learn about the harm being done.

michael sweet at 06:16 AM on 30 January 2023Checklist: How to take advantage of brand-new clean energy tax credits
Peppers,
Your post is confusing. It is not clear what you are in favor of and what you are railing against.
In post 1 you rail against electricity and the OP for supporting using more of it in our homes. In post 5 you support some uses of electricity but apparently not others.
Your data on heating homes using either gas or electricity is way outdated. A heat pump is more than three times more efficient than past electrical resistance heating so the cost of electrical heating by your numbers would be less than $60. Gas is much more expensive but since you have no reference it is impossible to know how much more expensive. Gas in 2022 was about triple the cost in 1999 and double the cost in 2021. source Gas prices are unikely to come down since so much is now exported. In addition, if you install a heat pump you get air conditioning for free. That is important in areas like Wshington state where the new temperatures need air conditioning becaause of global warming.
I find it amusing that you support pie in the sky like nuclear power and power beaming when neither of these technologies can compete on price with existing solar and wind. Solar and wind are the cheapest power in the world today. Installing as much renewable energy as possible as fast as possible will lower everyones power bills and clean up the environment at the same time. Your claims about more expensive power are simply false.

nigelj at 06:09 AM on 30 January 2023Checklist: How to take advantage of brand-new clean energy tax credits
Peppers,
Your main concern seems to be that the transition to renewables and an electricity based energy system is going to cost people money in various ways. And it will and personally I think we should just acknowledge that. However read the research studies and it wont cost so much as to be impractical, even based on known technologies now. Theres plenty of material easily googled.
You also mentioned that we are taking a leap of faith that the technology will improve and become cheaper in the future. Theres some truth in this to an extent. We can actually be quite confident that the technology will improve and costs will drop a certain amount, based on what we know, and various studies anaylse this, but we dont know with the same certaintly if the costs will drop a whole lot.
However we have no real other option than a new energy system, as a civilisation because we will run out of fossil fuels anyway or extraction costs will get prohibitive, sometimes in the next 50 - 100 years. A transition to an economy based on electricity or synthetic fuels is therefore inevitable. We will either sink or swim. The climate problem has just bought the issue forwards.
I do see some positives: In New Zealand electric cars with just modest tax payer subsidies are now cost competitive to buy with mid price family friendly ICE cars and approximately four times cheaper to run. The point being they are now an attrractive package all things considered and sales have increased recently. Plenty of studies show the planet does have enough raw materials for the transition.
Solar and Wind are now providing much lower cost power than fossil fuels (refer to the Lazard energy analysis available free online) although as we need to build storage costs will probably go back to where fossil fuel costs have been.
In my view nuclear power has its place because its clean zero carbon energy, but there isnt enough uranium to power the world entirely by nuclear power for significant lengths of time. Remember the uranium gets pretty much used up and cant be recycled as well as the materials used to make solar and wind farms. And building nuclear power stations is a painfully slow process. So nuclear power can only be part of the solution at best. Fusion power might be a good long term solution but is still decades away despite some recent advances.
Gas where I live does provide relatively low cost cooking and heating. For people very dependent on gas the transition to things like heat pumps would be expensive for them. This is an area where the government will have to assist people with the costs, and it seems that America is doing this given other articles on this website.
For all those reasons I strongly support the move to zero carbon energy with renewables as the main component of that, and I strongly support electrified transport, perhaps with some PHEV as well, although Im getting a bit doomy like Evan about how quickly we will do all this. However its better to at least try to make some progress than just bury our heads in the sand.

One Planet Only Forever at 04:13 AM on 30 January 20232023 SkS Weekly Climate Change & Global Warming News Roundup #4
The following CBC News item helps understand the challenges of getting people to learn about the harmful consequences of fossil fuel use, especially the climate change impact consequences.
Why don't we talk about acid rain and the ozone hole anymore? Scientists debunk misinformation
There are significant differences between the 'globally acted on and considered to have been reasonably resolved SO2 and Ozone issues' and the climate change harm of fossil fuel use. In addition to the 'immediate potential negative impact on influential people of a failure to address the problem' a major difference is the amount of 'developed perceptions of prosperity and superiority' that have to be given up to address the problem. However, there are other important things that can be learned from how each issue was addressed.
The SO2 (acid rain) problem was a developed problem that was impacting the environment that influential people, including large groups of voters, could identify with and potentially experience. But even the undeniable harm done did not motivate rapid correction everywhere. Some European nations led the transition to reduced SO2 emissions, including 'low sulphur' and 'ultra-low sulphur' diesel. Other nations, including the USA and Canada delayed implementing the harm reduction technology because of the competitive trade advantages of the lower cost of not leading the transition. That delay also kept cleaner diesel engines developed in the nations leading the transition from being import competition because they would not run as well on the dirtier fuel. But the major difference from the climate change challenge is that 'more harm done' was acceptable while technology development occurred to reduce the problem. And a critical difference is that sulphur emissions did not have to be 'almost entirely eliminated'. Also, removal of sulphur from the atmosphere is not required.
The ozone problem, like the SO2 problem, was also allowed to 'take some time to be solved'. And a major difference from the climate change challenge is that only a small part of the global economy was impacted by the required corrections of what had developed. The global agreement regarding the mitigation of the ozone problem was able to wait for new technology to develop. Also, the rate of harmful ozone impacts did not have to be brought to 'net-zero'. And actions were not required to remove harmful excess ozone impacts.
The climate change challenge requires the ending of a developed activity that is a massive part of the global socioeconomic system. And there is the added potentially unpopular requirement for the people who benefited most from the current accumulated problem to pay for removing excess harmful impacts. There is no time to wait for 'new cheaper technology to be developed' ('waiting for cheaper alternatives to be developed' through the past 30 years has developed the current undeniably harmful reality). The currently developed technology for removing CO2 needs to be built and be operating today. However, only technology that is well understood to have minimal 'other' negative impacts should be built and operated, even if cheaper alternatives are available.
For the climate change challenge, and so many other matters that matter to the future of humanity, the measure of acceptability of what has been developed and the alternatives needs to be 'essentially harmless'. Compromising the pursuit of being as harmless as possible 'because of other considerations' will fail to develop sustainable solutions. That reality is a major impediment to efforts to increase awareness and understanding of the climate change challenge. The science is solid. But it requires a lot of developed preferences and perceptions of status to be given up.

peppers at 02:00 AM on 30 January 2023Checklist: How to take advantage of brand-new clean energy tax credits
HI Forever (again!) and Micheal,
We do need to reduce co2 emissions.
Forever, correct at 61% from fossil, 19% nuclear and 20% alternatives from the Dept of Energy. I am a proponent of the nuke, based on outcomes of that becoming much cleaner, using own waste and the liquid salt as coolant being safer.
I did not look in to deregulating, but I see the outcomes of different types of fuel based on my observations over 45 years of landlording. Running electric heaters as opposed to natural gas is 5 times more expensive. $35 of NG heats a month of $170 electric heat in an apartment.
When I critique this article it is in the ways we fool ourselves that we are operating in achievable or useable terms. It takes 3 years of co2 ( of the replaced gas car) to make a Tesla, 2 to 3 years based on location and use factors. The diesel mining of the lithium, aluminum being 8 times more emitting than making steel, same plastic in the car, etc.
The main push is faith. That these processes will get better. But more than faith, this delves in to propaganda as well. Few to none of these things will address the issue except to cause more spending and higher bills. Tell me we are just hopeful these things will later address the situation and Ill see it as an honest communication to me.
But switching to electric can allow a larger bite of alternatives, when they can come in to play. Thats all that is being said. And many times the cost is supposed to be sucked up I guess. As if people have this money.
I also see this power beaming, aiming sunlight from orbit to power stations on earth. 24/7 is the key. THAT would be a wonderful use of money and tech. And the new nuke... All better than setting groups of people against other groups down here on earth.
Micheal, probably the most useful things on this list of ten are the 5 items of insulation, double pane windows and etc. We can afford to want that in the US, if we dont care to feed anyone else with those funds. We are at 15.6 per capita on emissions in the US and China emits twice what we do. But they are 4 times larger, meaning thier per capita is 7.5. If we could come to match thier per capita we would affect the co2 total 7% globally.
That does not strike me as fatalistic. It makes me want to aim efforts to things that will properly solve this. And as important, not have us fracture and fight and lecture on another on this.
Thanks tons, D

MA Rodger at 21:56 PM on 29 January 2023The connection between Hurricane Sandy and global warming
stranger1548 @9,
Perhaps a link to Kossin et al (2020) 'Global increase in major tropical cyclone exceedance probability over the past four decades' would assist.
More generally, idea that tropical cyclones will be fewer but more intense is a pretty basic finding when considering the impacts of a warmer climate. While the warmer seas will cause cyclones to reach higher intensities, the fators which assist in cyclone formation are reduced (cyclones being kilometer-high funnels built of nothing but swirling air).
Perhaps it is worth mentioning the problems of deciding if a storm in, say, the 1890s or even the 1950s reached Force 3 or even whether the number of storms in the early record is significantly wrong. Thus with reliable records stretching back just fifty years (so using satellite data) it is very easy to argue that any trends found in the records of storm numbers are just some form of natural variability. Where I think such argument can be dismissed is in the seasonal ACE data. The graphic below is a couple of years out of date (snatched from Wikipedia which also has an interesting graph plotting PDI & SST and which also needs updating [PDI is similar to ACE but for landfall cyclones]), with 2021 ACE=145 and 2022 ACE=95, thus 2022 breaking the run of "above normal" seasons. So over the full record back to 1850, we see 46 of these "above normal" seasons in the North Atlantic (the graph below only shows back to 1950) with 18 of these in the last 30 years and just 28 in the 143 years 1850-1992. And it is pretty-much impossible to find anything approaching the run of six "above normal" seasons 2016-21 in the earlier records, this accounting for the potential for any significant errors in those records.

Sorry, this is the only reference I could find to hurricanes. My question is that it seems I've for read for years that there is no scientific consensus on increasing numbers of hurricanes but that there is consensus on growing intensity. Exchanging posts with a skeptic I failed to back the statement on hurricane intensity. The studies I've looked use modeling the future but as we know the word modeling only receives derision from climate skeptics. I couldn't find any actual proof that hurricanes have intensified. I couldn’t find any climate signals that support the premise.

Charlie_Brown at 06:29 AM on 28 January 2023It's Urban Heat Island effect
HamletsGhost @69
You say “The Greenhouse Gas model does not account for any heat transfer arising from rain-cooled macadam.” By greenhouse gas model, perhaps you are referring to the models for radiant energy transfer in the atmosphere. MODTRAN In Infrared Light in the Atmosphere is one such model available to everyone and can be used to clearly demonstrate the powerful effect of greenhouse gases. Urban heat island effects, including changes to albedo, evaporation, transpiration, precipitation, and energy production, are negligible compared to radiant energy loss to space. Actually, while the changes in these effects are tiny, the hydrologic cycle, convection, and conduction in the troposphere are built into the atmospheric temperature profile (lapse rate) upon which radiant energy transfer models are based. All that you have described are ways that energy moves around within a small portion of the troposphere and they do not have any significant effect on the global average temperature profile of the atmosphere. You jump to an incorrect conclusion that “In omitting the fact of transfer, the Greenhouse Gas model must be inaccurate.” Then to say that “Within a model that takes into account UHI-created weather patterns and rain-cooled macadam, atmospheric increase in carbon dioxide is less as the cause of global warming than an index of burning” is simply not true.

One Planet Only Forever at 05:53 AM on 28 January 2023Checklist: How to take advantage of brand-new clean energy tax credits
peppers,
The latest data on US electricity generation appears to be on the following EIA Frequently Asked Questions response "What is U.S. electricity generation by energy source?"
That indicates fossil fuels are 61% of the generation mix in 2021. But that is declining. The 2022 percentage will be lower.
And the decline may be rapid. When was the "Over 80%" you referred to? In the recent past? Or are you recalling data from further in the past. The more recent the "over 80%" data point is the more rapid the decline of fossil fuel generation has been.
Anther important point is the fatal flaw of the developed socioeconomic-political systems that 'focus on the positives of lower cost' and 'dismiss or excuse any consideration of harm done'. More harmful is cheaper in most situations.
-
Bob Loblaw at 02:57 AM on 28 January 2023It's Urban Heat Island effect
The biggest failing in Hamlet'sGhost's comment #69 is his use of the phrase 'Greenhouse Gas model". There is no such model - what we do use in climatology is models of things like radiation transfer, energy conservation, fluid motion, conduction, the hydrological cycle, cloud formation and precipitation, etc., all built together into broad-scope "climate models". Greenhouse gas effects are the result of the well-understood radiation tranfser part of that - as they play out across all the combined physics.
There is also no such thing as an "Urban Heat Island model" - unless it's a creation of HamletsGhost's imagination. The urban heat island effect is a combination of energy balances, surface properties, changes in evaporation due to availability of water (see "hydrological cycle"), etc. All those physical properties and processes are part of "climate models" HamletsGhost's idea that UHI is something excluded from our climate models is bizarre.
In short, HamletsGhost has no idea what he is talking about.

Peppers,
Five of the ten tips do not involve electricity. What is your beef?
In any case, in order to control Global Warming we need to switch all energy use to electricity. The heat pumps described in two tips are much more efficient than fossil heaters. More efficient appliances save money even if electricity is expensive.
Similarly, electric vehicles are cheaper to own than ICE cars because they are much more fuel efficient and they require much less maintenance.
The remainng tips suggst that you plan ahead so that you can take advantage of as many rebates as possible. What is wrong with that?
Please pay more attention to the articles you comment on.

peppers,
My first observation is that you may have cherry-picked a location and a month as the basis for the claim you try to make.
My quick internet search for the broader matter of "california electricity prices" identified the following NYTs article "Why Are Energy Prices So High? Some Experts Blame Deregulation." that seems to provide an excellent explanation.
It appears that all of the states that 'deregulated' their electricity systems have seen their rates increased relative to the regulated states. And the higher costs are not due to the way the electricity is generated. They are due to the way that the deregulated system operates.

Evan,
I appreciate the value of the Keeling Curve as evidence that the required change of direction of over-developed harmful human ways of living is occurring. And, of course, my concern is all harms, not just climate change harm. But the generalized point can be made by focusing on climate change.
Developed popular and profitable climate change harm, the powerful resistance to ending the harm, and the even stronger resistance to repairing the harm done, is a clear example of many other harmful impacts developed by misleading marketplace over-development of human ways of living. And a very harmfully misleading aspect is a focus on the positives. That focus on the positives delays and resists learning about the negatives. It also excuses the negatives ‘because of the perceived positives’. An example of climate change impact reduction misleading marketing is the Alberta production of oil sands for export being claimed to be working towards being net-zero by 2050. That sounds good until you realize that there will be other harms produced by the activity in Alberta, potentially even new harms as a result of ‘focusing on the positives’ of the actions that ‘get to net-zero carbon impact of the part of the fossil fuel system happening in Alberta’. And the real eye-popping negative is that actions ‘outside of Alberta’ related to those ‘net-zero Alberta exports’ are not going to be close to net-zero. The total global impacts needs to be ‘net-zero’, not just parts of it. However, the impacts of people already living better than basic decent lives need to lead the transition to ‘total global net-zero’. So Alberta oil sands production becoming net-zero by 2035 would be genuinely helpful, with the understanding that before 2060 there would be no export market for what Alberta wants to benefit from exporting export.
Back to the Keeling Curve. In spite of the value of the Keeling Curve the more important measure of the required transition to limit harm done is the amount of global average surface temperature increase above pre-industrial levels. The uncertainty of the relationship between CO2 levels and resulting average temperature makes the temperature a more relevant measure. The science strives to narrow the range of CO2 levels to be targeted. But the understanding that 1.0 C is where we should be striving to eventually get back to in order to limit future harmful consequences is clear. And the CO2 levels for 1.0 C warming are now well known (proven due to the lack of corrections of development direction to limit harm done to 1.0 C). And the CO2 levels for 1.5 C warming will also almost certainly become known in the near future. Hopefully the CO2 levels for 2.0 C warming will never be proven by the lack of correction of human development. That is the ‘BIG IF’. The science is clear that ‘when’ the upper limit on global harm is reached the the higher the magnitude of that peak the more harm is done to the future. And the harm done includes the extra unprofitable effort required to bring the level of harm back down below 1.5 C. And the sooner it is brought back down the better. The science also indicates the disastrous consequences ‘If’ the correction does not happen, or happens too slowly (and the correction has been happening too slowly because of the incorrect economic ideology that requires ‘perpetually more, never less, especially never less for people with higher status and more power’).
Important points are:- ‘When’ is the appropriate term for the science of climate change impacts.
- ‘If’ is the term for socioeconomic-political results.
So my current understanding is that ‘when’, scientifically, total global human activity transforms to the point of no longer causing accumulating global warming impacts, and continues to transform to reducing CO2 levels at an increasing rate, there may even be a delay of response in the Keeling Curve.
The annual rate of human impacts is the important item to track. And the Keeling Curve is one of many measures for tracking harmful human impacts. Global fossil fuel use is another way to track things. The current situation is ‘human activity impacts cause significant annual increase of CO2 levels’. The curve of human impacts on CO2 levels needs to be brought down to ‘Zero’ and continue to be brought below zero, removing CO2, to limit and repair the harm done by human impacts. Admittedly some of the harm done will not be able to be repaired. And some of the repairs, like reversing glacier retreat (regrowing glaciers), may take a long time. So limiting the magnitude of harm done needs to be the ‘governing objective’ rather than compromising that objective by attempting to protect developed status quo perceptions.
That leads to understanding that continuing to ‘grow global economic perceptions based on the developed ideology that promotes the positives and tries really hard to ignore or dismiss the negatives’ makes the future required corrections more dramatic. And, pushed too far, the result will be socioeconomic-political collapse that ‘catches a lot of people by surprise’.
Optimism for the future of humanity does require the ‘ending of harm done’ to be ‘when not if’. There is no improving future for humanity ‘if harmful ways of living are not ended’. Developing harmless replacements for developed harmful ways of living can help. But some 'developed popular and profitable activities' likely need to be 'restricted to only help the poorest live better'. And the amount of harm done to the future continues to increase until the harmful activity is ended. And improving the future requires efforts to repair the harm already done. And all of that is contrary to developed popular socioeconomic-political ideology.

peppers at 21:05 PM on 26 January 2023Checklist: How to take advantage of brand-new clean energy tax credits
Electricity is a delivery method, not a power source. My fear is getting trapped in the higher cost. You can make electricity from natural gas for instance, but not the reverse, and over 80% of electricity is still made from coal, gas, etc. Here is a blurb about electricity costs ( in Ca. ): Bureau of Labor Statistics, Geographic Information, Western
News Release, 1/18/23: The 26.0 cents per kWh Los Angeles households paid for electricity in December 2022 was 57.6 percent more than the nationwide average of 16.5 cents per kWh. Last December, electricity costs were 69.0 percent higher in Los Angeles compared to the nation. An intregal part of this article is that electricity is a better costing alternative. It actually appears as a trap. -
MA Rodger at 18:03 PM on 26 January 2023Climate change: Water vapor makes for a wet argument
pewtergod @145,
It is actualy untrue to say H2O & CH4 absorb at the same frequency but such argument becomes a little technical so the exact wording of the claim is required to properly rebut what is being argued.
The graphic below is much-used (although not a good explanation of the power of CO2 as a GHG) and show the frequencies absorbed by different atmospheric gases. The Earth only emits at frequencies longer than 5 microns so it is only the right-hand portion of the graph which is of interest.
And even if H2O did absorb/emit at the same frequencies as CO2 it would be a flawed argument from the denialists as CO2 is present up to 50 km (way above the bulk of the H2O), and it is the height of emissions into space that determines the GHG effect.

pewtergod at 06:56 AM on 26 January 2023Climate change: Water vapor makes for a wet argument
Why can't I find anything about methane and water vapor?
Climate denialists keep saying they absorb the same frequency, and I can't find a rebuttal.
Moderator Response:[PS] Just enter "Water vapour" or "methane" in the search box on top left. You will find plenty like "Water vapour is the most powerful GHG" myth. (spoiler: water vapour is a powerful GHG but its concentration is temperature dependent so it is a feedback not a forcing). You find detail on relative importance of gases here.

Evan at 22:53 PM on 25 January 20232023 SkS Weekly Climate Change & Global Warming News Roundup #2
OPOF, thank you for your comments. We missed you in this conversation. :-)
"My current understanding is that when the Keeling Curve levels off, when human activity is no longer causing CO2 levels to increase, there should not be a significant further increase of the global average surface temperature."
According to the best climate science, IF, not when, the Keeling Curve levels off, we will still have "warming in the pipeline". To have no significant further increase of global average temperature the Keeling Curve must decrease, as would happen for a time if we were to reach net-zero emissions. This is what I address in my recent paper Climate Confusion.
I wrote that paper because there is confusion about the implications of different emissions pathways. Many are thinking that recent scientific research shows that we can limit the warming to no more than we've already caused, but as Hausfather notes, this science dates back to 2008 and is not a new result.
"The best available evidence shows that, on the contrary, warming is likely to more or less stop once carbon dioxide (CO2) emissions reach zero, meaning humans have the power to choose their climate future.
When scientists have pointed this out recently, it has been reported as a new scientific finding. However, the scientific community has recognised that zero CO2 emissions likely implied flat future temperatures since at least 2008. The Intergovernmental Panel on Climate Change (IPCC) 2018 special report on 1.5C also included a specific focus on zero-emissions scenarios with similar findings"
But it's rise to prominence now is causing confusion between what happens if the Keeling Curve levels off and what happens if we reach net-zero emissions. These are two different scenarios, but the science behind each has been known for a long time and is not a new result.

One Planet Only Forever at 15:35 PM on 25 January 20232023 SkS Weekly Climate Change & Global Warming News Roundup #2
I have been an interested follower of this discussion. I am optimistic about humanity in the long term, but pessimistic about the short term.
My current understanding is that when the Keeling Curve levels off, when human activity is no longer causing CO2 levels to increase, there should not be a significant further increase of the global average surface temperature.
However, I also understand that increasing temperatures will activate feedback mechanisms that will increase CO2 levels. Therefore, before the Keeling Curve is levelled off, any activated feedback mechanisms will require more reduction of human impacts than would have been required before the feedbacks were triggered. In other words, more warming makes it harder for humans to reduce human impacts enough to ‘level-off the Keeling Curve’ (get to net-zero).
Also, the science (from decades ago) indicates that warming above 1.0 C risks significant harm (now proven). And warming beyond 2.0 C is considered to be very risky (hopefully never proven). That understanding is the basis for the 1.5 C objective that is paired with the need to limit the peak impact level to less than 2.0 C. (Refer to 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”)
Developed governing economic ideology is justifiably questioned. The short term competitive pursuit of status interests over-powering the reduction of harm is detrimental to the global future of humanity. Also, the perceived need for constant growth of activity that is perceived to be profitable develops harmful results.
The removal of excess CO2, levels above 1.5 C impacts, is now almost certain to be required. CO2 impacts exceeding 1.5 C are ‘in the pipeline’ because it will take time to correct the current harmfully over-developed activity that is the result of a lack of actions to limit impacts through the past 30 years. And the marketplace will not naturally develop CO2 removal to bring peak human impacts back down to 1.5 C levels because that will never be a profitable activity. External governing will be required to make it happen.
External governing of economic activity will also be required to limit the amount that impacts exceed 1.5 C before they are drawn back down. A key understanding is that the area under the global average temperature curve needs to be minimized to limit the future challenges. The more that 1.5 C level of impacts is exceeded the more harm is done. The longer the 1.5 C level is exceeded the more harm is done. But the required changes of the developed governing socioeconomic-political systems are contrary to ‘popular developed socioeconomic ideology and the developed status-quo’.
So, in my comment @2 I expressed optimism about the long term future of humanity. However, I am also pessimistic about how harmful the impacts of the ‘over-developed harmful marketplace system fuelled by marketing that is focused on promoting positive impressions’ will be before that system is corrected (I made a similar point in my comment @4 on the SkS item “Can induction stoves convince home cooks to give up gas?”). That pessimism will be reduced when a significant amount of ‘unprofitable’ CO2 removal facilities are operating. The sooner those ‘correction of harm done’ facilities are operating the sooner there is justification for optimism that there will be a sustained improving future for humanity.
Many of the supposedly highest status people today are obliged to pay for carbon removal facilities to be built and operated in the current day. That activity cannot ethically be pushed off to be a ‘future, development that will continue to face reluctance to be implemented because it is not profitable’. And it is important for those ‘unpopular and unprofitable’ facilities to be almost certain to be harmless. Less expensive and ‘more harmful in other ways’ ways of appearing to reduce the harm of CO2 need to be understood to be unacceptable. It is important to see evidence of leadership pursuing the limiting of harm done, not claiming to be reducing harm done by actions that are harmful in other ways. All harmful impacts need to be limited to sustainable Planetary Boundary levels of impact, not just CO2.
Therefore, I am hopeful and optimistic about the long term future of humanity. But I am skeptical/pessimistic regarding how soon there will be evidence to support that optimism. I am justifiably concerned about how much harm will be done that future generations have to overcome in order to develop sustainable improvements. Sustainable improvements can be achieved almost Forever within the Boundaries of this One Amazing Planet if that is a governing objective, which it really should be.

Evan at 12:50 PM on 25 January 20232023 SkS Weekly Climate Change & Global Warming News Roundup #2
Rob, rather than a long rebuttal, I refer you to a paper I published recently on this very subject titled "Climate Confusion." In it I deal with the very subject we're discussing, and reference the Hausfather paper.
There are only very special conditions where we don't have warming in the pipeline: all of humanity come together to do the right thing and nature plays nice. I will continue to point people to the Keeling Curve as the best assessment of how we're doing and what to expect. In the meantime, Hausfather's paper presents a result of a scientific modeling study, and is not an assessment of the likely trajectory of the Keeling Curve.

Philippe Chantreau at 12:11 PM on 25 January 2023It's Urban Heat Island effect
A quick addition for the sake of clarity:
HamletsGhost mentions land breezes. A land breeze is kind of the opposite phenomenon of a sea breeze. In land breeze conditions, the land surface cools down and reaches a lower temperature than the adjacent sea surface. They are usually stongest in the morning, when the temperature gradient is the largest. As a result, air flows from the land toward the sea, where air rises by convection. Although some sea breezes are known to reach far over land (it's relative, the farthest reaches identified are about 200 miles in tropical regions), land breezes are usually weaker and seldom reach beyond the 30 miles range off the coast.
In any case, it is worth emphasizing that a land breeze brings cooler air from the land over the sea surface. A sea breeze occurs during the day, when the land surface heats up quicker than the water and reaches a higher temperature. Air then rises over land and cooler air comes from the sea. These local patterns have been studied.
There is research suggesting that increased urbanization plays a role in decreasing trends in sea and land breezes, although no clear trend appears to be identifiable on a larger, global scale.

I am also mystified by the energy budget here. Radiation absorbed by low albedo areas, tend to radiate that back in infrared which is absolutely part of the models. Conductive transfer to rainwater is negible by comparison. Take a small amount of conductive heat transfer from a very small part of the area of the world going into a very large body of water and I would challenge you to measure the effect. I suspect it would hard to measure the effect on even the rivers flowing through a city let alone the ocean but happy to contradicted by data

Eclectic at 09:13 AM on 25 January 2023It's Urban Heat Island effect
HamletsGhost @69 :
You propose interesting methods of heat transfer from cities to rural & marine regions (such as Siberia and the Arctic sea).
However, to be worth consideration of this matter, it would be necessary for you to give at least a rough approximation of the actual quantification of this proposed effect. Size matters.
In post #60 above, MA Rodger notes the world's urban area is about 0.12% of global area. How will that percentage (adjusted by its albedo difference from rural) alter the Greenhouse Gas related calculations of global warming? My off-the-cuff guesstimate is that the overall alteration would be a poofteenth* .
[ *poofteenth is a mathematical term recently adopted by analysts assessing various magnitudes of contribution from heating/cooling factors driving Earth's surface temperature ]

Rob Honeycutt at 05:29 AM on 25 January 20232023 SkS Weekly Climate Change & Global Warming News Roundup #2
Evan... The paper I'm referring to is the same Hausfather paper. In the link we've both cited the lede to the article seems pretty clear.
Media reports frequently claim that the world is facing “committed warming” in the future as a result of past emissions, meaning higher temperatures are “locked in”, “in the pipeline” or “inevitable”, regardless of the choices society takes today.
The best available evidence shows that, on the contrary, warming is likely to more or less stop once carbon dioxide (CO2) emissions reach zero, meaning humans have the power to choose their climate future. [emphasis added]

Evan at 04:38 AM on 25 January 20232023 SkS Weekly Climate Change & Global Warming News Roundup #2
Rob,
"Those are infinitely better challenges for humanity to face over a civilization ending 4°C+ planet."
Obviously I agree with this statement. But for the large voting population that still thinks climate scientists are being alarmists and feel that we can easily adapt, they will be more concerned about the supposed negative economic impact of taking action than they will be about the impact of a "small" amount of warming. I get this specific feedback from a lot of people whose opinions I respect.
I will change my view of the future when the upward acceleration of the Keeling Curve begins to slow. Not before.
Rob, you are making business analogies and projections which I respect, but businesses are usually selling things that people want. Getting to net zero requires an awful lot of negative emissions technologies that are effectively a tax, things that are likely to be strongly opposed.
My point is this. The more we sell to the not-very-well-informed people the idea that the future lies in our hands (i.e., future warming depends on future emissions and not past emissions), and the more we sell the idea that there is a renewable energy and EV revolution that will drastically cut our emissions, the more likely they will believe that all is well and no need to worry. We are effectively removing their impetus for revolutionary change and accepting evolutionary change as sufficient.
The Hausfather paper indicates that an immediate 70% reduction in emissions would get us to stabilizing atmopheric CO2 emissions, which effectively leaves warming in the pipeline (read here). That's 70% of emissions across the entire world and across every sector, including agriculture and deforestation. And that massive effort still leaves warming in the pipeline. Then year on year that 70% reduction has to grow to keep theatmospheric CO2 concentration from increasing.
Therefore, (repeating myself here) I continue to advise people to expect that the current atmospheric CO2 levels correspond to committed warming. If and when the upward accelerationg of the Keeling Curve begins to slow, I will modify that advice. Until then, I think it prudent advice.

Rob Honeycutt at 02:07 AM on 25 January 20232023 SkS Weekly Climate Change & Global Warming News Roundup #2
Evan... I was being sarcastic by inferring a complete collapse of modern civilization would also bring us to net zero.
This is the element of your statements that I'm challenging here: "...even if we reduce our emissions that feedbacks in the system may continue to drive the Keeling Curve upwards..."
Two years ago I would have agreed. Based on more recent research it's far from certain and may not be correct at all.
I think one other thing history teaches us is that early research is slow, difficult and costly (and that's where we've been). But once we get to a cost effective point markets can scale very quickly (and that's where we're headed). This very moment in history we are probaly at the inflection point between those two.
Renewable energy markets have been ploughing through R/D, getting through the expensive Valley of Death, and are now emerging with highly profitable businesses. I think the challenges in the coming 30 years are going to be more related to resource availability over carbon emissions. Those are infinitely better challenges for humanity to face over a civilization ending 4°C+ planet.

HamletsGhost at 00:51 AM on 25 January 2023It's Urban Heat Island effect
In my view, the most important — and understudied — effect of UHI as it relates to global warming is the fact that large expanses of macadam act as heat sinks. This resuts in the phenomenon where by cities create their own weather: on the coast, UHI-expanses like that of Houston increase the effect of the landbreeze; stack moisture in clouds at a higher rate, and, eventually, drop more water onto the heat sinks. The rain cools these heat sinks off and, in the process, transfers warmer water into aquifers that feed the Gulf Stream.
Our senses, higher summer temperature readings at airports, and the chart above showing no significant difference over time between the temperature increase in rural and urban areas tells us this heat transfer is significant.
The UHI heat-transfer model explains both the effect on the polar ice cap and the warming of tropical waters. The Gulf Stream, now warmer than otherwise, leads up to the arctic polar ice cap and melts it. In the summer months, the Gulf Stream slows its transfer of warmer water into cooler water so that warmer water remains in Caribbean to develop into storm.
The Greenhouse Gas model does not account for any heat transfer arising from rain-cooled macadam. In omitting the fact of transfer, the Greenhouse Gas model must be inaccurate.
Within a model that takes into account UHI-created weather patterns and rain-cooled macadam, atmospheric increase in carbon dioxide is less as the cause of global warming than an index of burning.

slumgullionridge at 20:47 PM on 24 January 2023Input to USDA about how to allocate IRA climate-smart agriculture funds
Placing these IRA funds in the hands of the USDA is, again, an unuseful vehicle for the objectives advanced by the legislation. CCL either ignores the ample peer-reviewed science challenging the very existence of industrial animal agriculture, or are simply unaware of its presence in the literature. The work of Christine Jones, PhD, the Australian soil scientist, shows the adverse effects of livestock on the planet, she being only one of the scientists suggesting the elimination of livestock farming as a significant partial solution to the climate problem.
Moreover, CCL is either unaware or unconvinced that the heavy losses of phytoplankton render reforestation a futile remedy to the planet's growing oxygen production deficit.
The "livestock will save us" mantra of the Allen Savory school continues to dominate public policy, apparently because global animal agriculture employs over two billion humans, thus disabling the general public's acceptance of the scientific evidence showing otherwise.

Evan at 12:43 PM on 24 January 20232023 SkS Weekly Climate Change & Global Warming News Roundup #2
I'm not sure on what basis you say that we will get to net zero emissions. Yes, airplanes eventually run out of gas and crash. If that's what you're referring to, then it is a moot point. When we talk about getting to net zero emissions I am framing it in the context of doing so while simultaneously preserving something that resembles our current civilization. That represents a planned landing, not a crash.
The problem with talking about net zero emissions is that this is only one component of what drives the Keeling Curve. I originally responded in this thread to the issue of whether there is effectively warming in the pipeline. That is governed by the behavior of the Keeling Curve. Even if we get our emissions to 0, we may have already triggered feedbacks that cause atmospheric CO2 to continue to rise. That is, the longer we delay, the less we are able to affect the behavior of the Keeling Curve.
Long story short, given the difficulty of reducing our emissions, and given that even if we reduce our emissions that feedbacks in the system may continue to drive the Keeling Curve upwards, I think it a far safer bet to assume that there is warming in the pipeline equivalent to the current atmospheric CO2 concentrations. It's been 35 years since the IPCC was established, and if history has taught us anything, it takes far longer than people project to bring about the kind of change needed to reach net zero emissions.

Long:
Although this is an old thread, comments never close here at SkS - for just the reason that someone may want to discuss them again in the distant future.
Institutions will differ; countries wll differ. Funding can be quite complex.
My own experience in universities is within Canada, and from roughly 30 years ago. Times have changed. Academic positions will have rules that affect what sort of outside contracts a professor may hold - but expectations may differ even between departments in the same university.
Where I was (Geography), outside contracts and external activities that took away from your research time were not looked upon all that favourably, but my understanding was that within some other departments - e.g. Engineering - that outside consulting work was essential to advance your career. If you weren't getting outside contracts for "real engineering" work, what good were you? At least in our academic environment your entire salary was typically covered by the university for the entire calendar year.
My understanding was that many U.S. universities only paid a professor's salary during the school term, and you had to get outside funding that included salary dollars for yourself during the summer (non-teaching) periods. That could come from grants, etc.
In Canada, major academic granting agencies would not allow grant money to go to the principal investigator's salary - but it could go to grad students or post-docs. In the U.S., grant money for your own salary was more or less expected. Institution claw-backs for "administrative overhead" could also vary, depending on the institution, the type of funding, etc.
In the example above (comment #3), clearly part of the contract was going to Soon as salary - but there is no indication whether this is to cover his regular salary, or is an extra "perk". Either way, though, Soon benefited personally, directly from that contract.

Evan... Oh, we absolutely will get to net zero carbon emissions. There's no doubt about that. It's a little like flying an airplane. You're eventually going to land, it's just a matter of how you land.
My personal optimism comes from the fact that energy technologies are coming forth in rapid succession. Years back I remember wondering why so much money was being poured into off-shore wind when the cost was >$300/MW. Then, I watched turbines escalate in size and fall in cost and I went, "Ohhh..." Same is happening with grid storage now. There are certainly going to be physical constraints to each solution that comes to market, but fortunately lots of solutions are coming to market.
All (or nearly all) energy generation plants are going to be replaced over the coming 30+ years. It already makes little sense to invest in new FF plants. There are aspects of decarbonization that are going to be more tenatious problems to solve, but I know smart people are eager to work on those problem. My larger 30,000 ft level view concern is the general notion out there that nothing is being done, and it's just plain wrong. People have been working on this for decades and those efforts are clearly bearing fruit.
Regarding the Keeling Curve, I believe it's going to be a lagging indicator of what's happening, and figures related to the growth of renewables (which have been tragically underestimated) is more of a leading indicator.
The biggest wild card, in my mind, is human behavior. We're sure to see some pretty serious socio-political upheaval over the coming 30 years. My biggest concern is whether such disruptions will further delay progress right as we need to further accelerate progress.

Evan at 03:28 AM on 24 January 20232023 SkS Weekly Climate Change & Global Warming News Roundup #2
Thanks Rob for your comments.
I agree with most of your points, but differ in messaging. Climate scientists, and even yourself, use the phrase "Once we get carbon emissions down to net zero," as though it is a foregone conclusion that we will. For the not-so-well-informed, watching from a distance layperson, one could get the feeling that we've found a way out of our mess, that we're well on our way, and that the current rollout of renewable energy and EVs will solve the problem. Yes, there are promising technologies, but rolling them out across the globe and replacing, not supplementing the fossil-fuel industry, is quite another matter. This all assumes, of course, the renewable energy is replacing fossil-fuel energy. Or is renewable energy merely allowing cheap expansion of more generating capacity? Rapid growth of renewable energy does not mean we are reducing emissions.
And as you well know, energy consumption is just one part of the problem.
I am not trying to spread pessimism. I am trying to help people prepare for a likely future. It is far more likely that we will have warming in the pipeline for decades to come, than not. It is far more likely that our current CO2 concentrations represent committed warming than not. The fact that the future theoretically lies in our hands and depends on what we do, cannot be construed to give us a likely future where we get to net zero emissions by 2050.
Take a look at the following graph, where I've taken the 1970-2005 upward accelerating trend line and projected it forward. The 2010, 2015, and 2020 data all lie about this upward accelerating trend line! I don't see any indication of an inflection point. What I do see is a hint, not proof, but a hint that the trend line is more than accelerating upwards.
For all of our sakes Rob I hope you're right and that I'm wrong. But the Keeling Curve only tells me one message. Time to prepare for a very tough future. We're in the middle of building a house now, and we're putting a lot of money into building it strong, into a ground-source heat pump, and into an expensive roof that can withstand high winds and hail. In short, the Keeling Curve is suggesting that we must build far beyond current building codes to keep up with the changing climate.
I am serious, though, when I say that I hope you're right and I'm wrong. I don't want to be a pessimist. But I do want to help people prepare for the likely future.

Evan @13... I don't think "scientists" make such a mistake, nor do they make specific assertions about whether we will or won't get to net zero.
Climate research offer up a very wide range of potential outcomes, since obviously no one can predict future events. All researchers are doing is saying "if" we get to net zero (and there certainly is a chance we can achieve this in the next 30 years) then warming should stop as we reach that level.
You say, "But so far, nothing we have done has slowed the upward acceleration of the Keeling Curve." I think the challenge there is, when you're at the inflection point it's very hard to determine where the trend is going to go by eyeballing charts.
I remain positive on this topic because I do see things are happening. Every day when I read the news I see new technologies and new strategies aimed at elimination of greenhouse gases. I know that renewable energy is now the cheapest energy available and is continuing to fall in cost, and it's now scaling exponentially.
I also find pessimism to be a mindset that robs people of motivation to achieve new things. By framing the issue as "we're screwed" tends to act as a self fulfilling prophecy.
I am realistic in that I know for certain things are going to get worse. The tasks ahead are gargantuan. The impacts are going to affect different people to different degrees. But there are levels of how bad this gets. As Dr. Stephen Schneider said, "'End of the world' and 'good for us' are the two lowest probability outcomes."

Take a look at the following curve that I published in Addressing the Climate Crisis: Evolution or Revolution. It suggests a very strong connection between population and the accumulation rate of CO2 in the atmosphere, spanning many different levels of technology and governance. It also illustrates our path to net zero emissions, even though this graph only shows our path to stabilizing CO2, and not to net zero emissions. My point in bringing this up is that we must not speak confidently of reaching net zero emissions as though it will happen. If all we did was to follow the path to net zero accumulation, that would still leave "warming in the pipeline".
I also offer thoughts on this issue in a separate post, Climate Confusion, where I address this issue of prematurely concluding that there is no longer warming in the pipeline. Some people are becoming confused by the scientific messaging, thinking that warming in the pipeline represents old science. The only way we avoid warming in the pipeline is by going beyond atmospheric CO2 stabilization and getting it to drop. Here is a graph of what the warming would look like if we stabilized CO2 immediately, and reached net zero emissions by 2100.

"But so far, nothing we have done has slowed the upward acceleration of the Keeling Curve."
I cannot ignore the past, and there's more than enough evidence to show the role of government and fossil fuel's role in the Keeling Curve's relentless climb. James Speth, "They Knew" and Juliana vs The United States ), and the Climate Files scream at us to stop burning fossil fuels.
We have no real cause to doubt the inexorable climb of the Keeling Curve and our reliance on passing the buck to the next generation, as they will do to the next generation.
I have a sense of the frustration Galileo must have felt.

One Planet Only Forever at 04:39 AM on 23 January 2023Can induction stoves convince home cooks to give up gas?
The following NPR article, “Gas stoves became part of the culture war in less than a week. Here's why”, shows that the people who want to benefit from prolonged, or increased, gas burning jumped on, and dumped on, the report of the study about the harms of cooking with gas.
Marketing promoting the ‘positives’ of anything is actually a serious problem. And consumerism fuelled societies are full of it. Exclusively selling positive impressions, including selling how a product or service will alleviate unjustified fears like the health and cosmetic industry does, builds popular support and profitability. And that popularity and profitability can cause people to resist learning about harmful aspects of what they have been enticed to develop a liking for. People can be harmfully tempted to like leadership that makes-up things to be feared and claims to fight against the created, but unjustified, fears and anxiety. And a nasty twist of that understanding is the ways that misleading marketing can get people to believe that climate change impacts are a ‘made-up fear’.
Most of the societies in human history that are perceived to be more advanced and superior, aspired to by others, can be understood to have been governed by misleading marketing and a related resistance to learning to be less harmful and more helpful to others.
Human history is also full of evidence that a portion of the harmfully governed dominant populations have tried to promote learning about the harmful realities of the supposedly advanced and believed to be superior societies and cultures.
The challenge continues to be breaking that cycle to get an increasing amount of human activity governed and limited by the pursuit of learning about what is harmful. That requires leadership actions that understandably reduce real harm done, repair harm done, and help people who genuinely need assistance to live a basic decent life. All human activity being governed that way would develop amazing sustainable improvements.

"Once we get carbon emissions down to "net zero""
The mistake scientists are making is assuming so strongly that we will get to net-zero emissions, that they are already saying there is no warming in the pipeline because we will get to net-zero emissions. There is no evidence to suggest that we will reach net-zero emissions, but there is ample evidence to suggest that we will continue with emissions sufficiently high to effectively guarantee warming in the pipeline.
It is merely a theoretical conclusion that there need not be warming in the pipeline, but this is a theoretical conclusion that currently appears to be completely disconnected from our actions. I am planning my life and recommending that others plan as though there is warming in the pipeline. If, not when, we get emissions under control, we will be that much better off. But so far, nothing we have done has slowed the upward acceleration of the Keeling Curve. There is lots of talk and plans, but it is relatively easy to get a small sector of the world to agree on what we need to do. It is an entirely different matter to get the rest of the world to follow suit.
