A case for ‘Climate Humility’: Analyzing the DOE’s ‘A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate’

Honestly, I never thought I’d see the day. To quote Mr. FOIA from ClimateGate, “A miracle has occurred.

Yesterday’s release of the DOE’s A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate is a watershed moment in the ongoing debate over climate policy in America. Why? Because for the first time, a major U.S. government agency—on official letterhead and with a blue-ribbon cast of authors (John Christy, Judith Curry, Steven Koonin, Ross McKitrick, and Roy Spencer)—has published an open challenge to the central claims, data handling, and even the motivations behind mainstream climate science and policy.

This isn’t just another technical report. It is a systematic rebuke of accepted climate “wisdom,” and it does so with unusual clarity, scientific rigor, and (at times) a sense of humor often absent in climate documents. Most importantly, it directly confronts the exaggerated and politicized rhetoric that has dominated headlines for decades.

The Executive Summary from the DOE web page:

This report: 

  • Reviews scientific certainties and uncertainties in how anthropogenic emissions of CO2 and other GHGs have affected, or will affect, the Nation’s climate, extreme weather events, and metrics of societal well-being.
  • Assesses the near-term impacts of elevated concentrations of CO2, including enhanced plant growth and reduced ocean alkalinity.
  • Evaluates data and projections regarding long-term impacts of elevated concentrations of CO2, including estimates of future warming.
  • Finds that claims of increased frequency or intensity of hurricanes, tornadoes, floods, and droughts are not supported by U.S. historical data.
  • Asserts that CO2-induced warming appears to be less damaging economically than commonly believed, and that aggressive mitigation policies could prove more detrimental than beneficial.
  • Finds that U.S. policy actions are expected to have undetectably small direct impacts on the global climate and any effects will emerge only with long delays.

What Makes This Report Unique?

  1. Official Status and Author Independence
    Unlike think tank white papers or “dissenting” journal articles, this report comes from within the federal government, under the Trump administration’s DOE. Yet the authors assert full independence—no editorial oversight, no political vetting. It’s rare to see scientists of this caliber (with backgrounds at NASA, IPCC, and major universities) allowed to directly challenge prevailing policy narratives with government resources behind them.
  2. Comprehensive Critique, Not Just a Narrow Rebuttal
    Rather than focusing on a single point of controversy, the report systematically evaluates everything from CO2’s physiological role in plant growth, to climate sensitivity estimates, to the track record of climate models, to the real-world impacts (or lack thereof) on extreme weather and U.S. agriculture. Each chapter is loaded with extended quotes from peer-reviewed literature and clear explanations of scientific uncertainty and model error.
  3. Explicit Address of Policy Missteps and Economic Risks
    Most uniquely, the report doesn’t stop at “science.” It details the economic costs of climate policy—especially the social cost of carbon modeling games and the virtually undetectable impact U.S. mitigation will have on the global climate. This is a rarely admitted fact, buried in most government assessments but here discussed openly and at length.
  4. Direct Critique of Media, IPCC, and U.S. National Climate Assessments
    In one chapter after another, the report highlights the misuse of worst-case scenarios (RCP8.5), the prevalence of “publication bias” in alarming ocean acidification studies, and the outright neglect of positive CO2 impacts like global greening. The report does not hesitate to call out “systemic misuse of scenarios in climate research” and points to specific agencies and news outlets responsible for propagating misleading claims.

My List of the Eight Most Important Findings in the Report

  1. CO2 Is Not a Conventional Pollutant and Has Direct Environmental Benefits
    Unlike actual pollutants, CO2 has no toxic effect at ambient levels, is essential for plant life, and has caused global greening—a fact barely acknowledged in IPCC summaries.
  2. “Ocean Acidification” Fears Are Overblown
    Oceans are still alkaline, and changes in pH are within natural variability; most ocean life evolved under much lower pH. The report exposes publication bias and lack of reproducibility in many alarming acidification studies. The Great Barrier Reef is currently thriving.
  3. Climate Models Consistently Overestimate Warming
    Most climate models run “hot,” overstating recent warming at the surface and in the troposphere. Data-driven climate sensitivity estimates are lower and more constrained than model-based ones, challenging the high ECS values used to justify drastic policy measures.
  4. No Evidence for Increases in Most U.S. Extreme Weather
    U.S. historical data shows no long-term upward trend in hurricanes, tornadoes, floods, or droughts. Claims of worsening disasters are unsupported by observations; fire trends are largely due to land management, not climate change.
  5. Sea Level Rise Is Not Accelerating Dangerously
    Global sea level has risen about 8 inches since 1900, but regional U.S. sea level trends are dominated by local land movements, not acceleration from climate change. Tide gauges do not show alarming acceleration.
  6. Attribution of Warming to CO2 Is Far Less Certain Than Claimed
    Natural variability, incomplete data, and significant model uncertainties make attribution of observed warming and extremes to human CO2 emissions tenuous. Solar variability may be underestimated in mainstream assessments.
  7. The Social Cost of Carbon (SCC) Is Largely Arbitrary
    SCC estimates, which drive regulatory costs, are shown to be highly sensitive to model assumptions, with no robust economic basis. The report demonstrates that realistic ECS values and updated economic inputs lead to much lower SCC estimates.
  8. U.S. Emission Reductions Will Have Negligible Impact on Global Climate
    Even extreme U.S. policy actions will produce climate changes too small to detect for generations—an inconvenient truth almost never discussed in mainstream policy or media reports.

Here is a Breakdown of How the Report Challenges Mainstream Climate Science

CO2: Pollutant or Plant Food?

The DOE report begins by demolishing the notion that CO2 should be treated as a conventional pollutant, as regulated under the Clean Air Act. It cites OSHA exposure limits (5,000 ppm—orders of magnitude above outdoor levels) and presents robust evidence from plant physiology showing that rising CO2 enhances growth, improves water use efficiency, and has led to the global greening phenomenon observed by satellites.

Notably, the report details how IPCC assessments downplay or omit this global greening effect, despite its direct connection to rising CO2. Even the IPCC’s own Special Report on Land concluded “with high confidence” that greening has occurred, yet this is absent from summary reports intended for policymakers and the public.

Ocean “Acidification”: A Manufactured Crisis?

The report’s treatment of ocean acidification is a case study in scientific skepticism. It points out that “acidification” is a misnomer—oceans remain alkaline, and pH fluctuations are within historic norms. Life in the ocean evolved under a much broader range of pH conditions. More importantly, the DOE authors highlight the growing recognition of “publication bias”: studies with null or minimal impacts from declining pH are difficult to publish, leading to a skewed scientific record.

A meta-analysis cited in the report finds a strong “decline effect” in ocean acidification impacts on fish behavior: early alarming results are rarely replicated by later, larger studies, which usually show negligible impacts. In short, the “crisis” has been grossly exaggerated in the literature and the media.

Model Failure: The Emperor Has No Clothes

The centerpiece of the DOE critique is the performance of global climate models. The report notes that despite decades of effort and billions spent, model projections have failed to narrow the uncertainty in equilibrium climate sensitivity (ECS). In fact, the spread of ECS in the latest (CMIP6) models has grown wider, not narrower, and the majority of models produce too much warming compared to observations—both at the surface and throughout the troposphere.

Crucially, the report provides detailed side-by-side comparisons of model projections versus observed data (see page 33–37). It notes that only models with the lowest ECS values match the actual temperature record since 1979. The majority of models overestimate warming, in some cases by more than a factor of two.

The report also skewers the widespread misuse of “worst-case” emissions scenarios (RCP8.5) in research and media. It cites analysis showing that the vast majority of climate impact papers used RCP8.5 as a business-as-usual baseline, despite the scenario being grossly implausible and far above observed emissions trends.

Attribution and Natural Variability

The report spends several chapters dissecting the uncertainties around attribution—the attempt to link observed warming and extreme events specifically to human GHG emissions. The authors document the wide range of natural variability (including the still-uncertain role of solar variation), and show that statistical “fingerprinting” methods are often inconclusive or circular. In some key cases, model simulations of vertical temperature profiles and the geographic distribution of warming simply fail to match real-world data—a fact not honestly conveyed in mainstream summaries.

The Social Cost of Carbon: An Economic Mirage

One of the most policy-relevant chapters debunks the “social cost of carbon” (SCC) calculations used by regulatory agencies to justify massive economic interventions. The DOE report shows that SCC values are essentially “made up,” highly sensitive to a few subjective assumptions about climate sensitivity, discount rates, and economic damages. When updated with realistic parameters and best-estimate ECS values, the SCC drops dramatically, sometimes to near zero or even negative (i.e., net benefits from CO2 emissions due to agricultural gains).

U.S. Policy: All Pain, No Gain

Perhaps the most striking section (and one likely to cause heartburn in certain policy circles) comes at the end: the scale of the U.S. impact on the global climate. The report quantifies just how little effect even the most aggressive U.S. mitigation policies will have—using the very models and assumptions of mainstream climate science. The answer: “undetectably small” impacts, appearing only after centuries, if at all. This fact is never honestly presented in the typical policy debate.

Of course, the Media is Panning It

Predictably, the release of the DOE report has drawn fire from mainstream outlets and climate advocacy groups. For example, the ever angry and alarmed, The Guardian wrote:

“Climate scientists have condemned the DOE’s new report as ‘dangerous disinformation,’ claiming it was designed to mislead the public about the risks of greenhouse gas emissions and to justify a rollback of U.S. climate policy. Several experts criticized the report for cherry-picking studies and downplaying the consensus on climate risks.”

LOL. Let’s address these lightweight claims, point by point:

Claim: The report is “disinformation” and “cherry-picks” studies.
Pushback: The DOE report is authored by respected scientists with deep experience in climate modeling, attribution, and atmospheric science—many of whom have published widely in peer-reviewed journals. The report is overwhelmingly referenced, including citations from the very IPCC reports it critiques, and in fact spends entire chapters reviewing both sides of contested issues. The presence of extended quotations from mainstream literature, including detailed reviews of opposing arguments, refutes the idea that it is simply “cherry-picking.”

Claim: The report “downplays the consensus” on climate risks.
Pushback: The DOE report does not deny climate change or human influence. It argues, with substantial evidence, that the level of risk is greatly overstated, that models exaggerate sensitivity, and that the costs of mitigation policies are vastly underestimated. It is not “disinformation” to present documented, peer-reviewed evidence that calls into question apocalyptic scenarios—especially when such scenarios are contradicted by the data.

Claim: The report is designed to justify policy rollbacks.
Pushback: The report’s authors explicitly state their independence and reject any suggestion of political vetting or pressure. They also include dissent and debate within the team. The report’s focus is on evidence, not policy prescription. The fact that it challenges established policy is a sign of its intellectual independence, not its bias.

Gavin Schmidt’s “RealClimate” website barely managed a whimper, starting an open thread, saying:

The EPA, along with the “Climate Working Group” of usual suspects (plus Judith Curry and Ross McKitrick) at DOE, have just put out a document for public comment their attempt to rescind the 2009 Endangerment Finding for greenhouse gas emissions.

I got a real laugh out of one of the four comments so far:

Secular Animist says

29 Jul 2025 at 4:35 PM

The proposed rule to rescind the 2009 Endangerment Finding is an ACT OF WAR against the human species by the fossil fuel industry.

LOL, bring it, you anonymous dork.

My Cold Hard Facts Conclusion

The DOE’s A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate stands out as a landmark challenge to the status quo in climate science and policy. It is a detailed, referenced, and balanced review—one that will make uncomfortable reading for those invested in climate alarmism or rigid consensus. It doesn’t offer certainty; it offers scientific humility, transparency, and an honest assessment of the uncertainties and limitations in current climate science.

The real “dangerous disinformation” isn’t in this report—it’s in the repeated failure of the mainstream media and science to confront inconvenient evidence, model errors, and the economic reality of climate policy. It’s long past time for the climate debate to embrace the kind of open, skeptical, and evidence-based assessment represented in this DOE report.

so we label as AI everything that hurts you? This is silencing as I have reported many times happening in this platform so that you can maintain you echochamber of propaganda… and you call yourselves supporters of freedom of speech and skeptiks…

The Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate (2025) by the Climate Working Group loses a lot of credibility because it cherry-picks evidence and presents climate science in a really one-sided way. That kind of selective framing can mislead both policymakers and the public.
For example, it goes all-in on the idea that more CO₂ is great for plants, pointing to things like global greening and better crop yields (see Section 2). But it barely mentions the flip side: how climate-driven droughts are already hurting plant growth, lowering crop yields, and even killing forests. There’s solid research on this (like Lesk et al., 2016, and Allen et al., 2015), showing how water stress can cancel out the supposed benefits of CO₂.
The report also downplays major climate risks, like the possible collapse of the Atlantic Ocean circulation (AMOC), brushing them off as unlikely without acknowledging their potentially massive consequences something the IPCC AR6 takes seriously.
It criticizes climate models for being too warm (Sections 5.2–5.4), leaning heavily on selective studies like McKitrick and Christy (2020), but skips over improvements in newer models (like CMIP6) or the role of natural varibility, which weakens the argument.
When it comes to extreme weather (Sections 6.2–6.5), the report highlights that there’s no long-term trend in U.S. hurricanes and tornadoes, but sidesteps clear evidence linking human activity to more heatwaves and heavy rainfall. Just look at the deadly 2021 Western North America heatwave Philip et al. (2022) showed it was made far more likely by climate change.
The report also leans on Connolly et al. (2021) to push the idea that the Sun has played a big role in recent warming, but ignores more up-to-date solar research from people like Chatzistergos (2022, 2024), Krivova, and Solanki. Chatzisergos (2024), for instance, debunked the old Hoyt and Schatten solar reconstructions and showed solar variability has been tiny nowhere near enough to explain the warming we’ve seen.
Its take on the Social Cost of Carbon (SCC) mentions how sensitive it is to assumptions but skips over newer, more policy-relevant approaches like target-consistent pricing. It also overemphasizes the worst-case RCP8.5 emissions scenario and barely touches on more realistic ones like SSP2-4.5, which skews how it talks about future risks.
Claims about urban heat distorting temperature records (Section 3.3) ignore the fact that datasets like HadCRUT5 already correct for that, so it doesn’t really hold up.
Even when talking about coral reefs (Section 2.2.2), the report highlights signs of recovery (like AIMS, 2023), but glosses over real threats like ongoing marine heatwaves (see Woods Hole, 2023).
Finally, the foreword from Secretary Wright frames climate change as a “challenge, not a catastrophe,” which kind of sets the tone for the whole report and makes it feel more like a politically motivated document than an independent scientific review.
In the end, by ignoring major counterarguments, downplaying real risks, and leaning too hard on selective evidence, the report just doesn’t give a fair or full picture and that’s a problem if we’re trying to base smart climate policy on it.
Pure propaganda for a report, celebrated by ignorant people in echo chambers and disinformation blogs.

how climate-driven droughts are already hurting plant growth, lowering crop yields, and even killing forests.”

Where is your proof of this? Grain crop yields are on a 30 year trend of continued record harvests for grains. What forests are being killed? Killed by CO2? What’s the process causing this?

What climate-driven droughts? As the article states: “Finds that claims of increased frequency or intensity of hurricanes, tornadoes, floods, and droughts are not supported by U.S. historical data.”

possible collapse of the Atlantic Ocean circulation (AMOC)”

Just how possible is this? 10% chance? 50% chance? Without actual estimates that can be tested in the real world this is nothing more than “scary propaganda”.

“clear evidence linking human activity to more heatwaves and heavy rainfall”

What clear evidence? Reference please. How do “heavy rainfall” and “increased droughts” go together? Sounds like just saying what is needed in the moment – even if the assertions are contradictory.

“ignore the fact that datasets like HadCRUT5 already correct for that, so it doesn’t really hold up.”

Those “corrections” are poorly documented and have large internal uncertainties of their own.

Pure propaganda for a report”

“Station Temperature Data”. On the “World Map”, click on a region or country to access temperature data from over 200 weather station located around the world that show no warming up to 2002. These charts of temperature falsify the hypothesis that the increasing concentration of CO2 in the air causes an increase in surface air temperature.

The main green house gas H2O is what keeps the earth warm except in the winter And 71% of the earth’s surface is covered with H2O. Did you go to John Daly’s website to check out all the charts from the many weather stations? Did you read any of the articles?

Now check this out. Shown in Fig 7. (See below) is the IR absorption spectrum of a sample of Philadelphia inner city air from 400 to 4000 wavenumbers (wns) There are some addition peaks for H2O down to 200 wns which are not shown since the cut off the spectrometer is 400 wns. Note the temperature and RH. Only the absorption peaks for CO2 and H2O in the 400 to 700 wn range are involved in the greenhouse effect. Note how very sharp the CO2 peak at 667 wns is. The CO2 molecule are absorbing very little energy. In 1999 the concentration of CO2 at the MLO was ca 370 ppmv. One cubic meter of this has a mass of ca. 1.16 kg and contains a mere 0.635 g of CO2.

The gas cell was an 7 cm Al cylinder with KBr windows. The absorbance of the CO2 peak at 667 wns is 0.025. If the cell was 700 cm (23 ft) lenght, the absorbance would be 2.5 and 99+% of the IR light would absorbed, i.e., the absorption of IR light is saturated.

A major process for warming of surface air is conduction
and convection. The wind is a force for sweeping warm air right at the surface up into the air.

Page down and read my comments to Kip H.re the CO2 absorption saturation effect.

RE: No Warming Of Air in Death Valley.

Shown in the chart see below are plots of temperatures at the Furnace Creek weather station from 1922 to 2001. In 1922, the concentration of CO2 was ca. 303 ppmv (0.59 g CO2/cu. m.), and by 2001, it had increased to ca. 371 ppmv (0.73 g CO2/cu. m.), but there was no increase surface air temperature at this remote arid desert. The reason the was no increase in air is that the absorption of out-going long wavelenght IR light has become become saturated when the concentration of CO2 reaches 300 ppmv. What this means that increasing the of CO2 above 300 ppmv will not result in an increase in surface air temperature.

For more info on the CO2 IR absorption saturation effect see:

https://climateatglance/carbon-dioxide-saturation-in- the-atmosphere.
This is web page at the Heritage Foundation.

https://arixv.org/pdf/2004.00708v1 or https://arixv./abs/2004.0078
The title of the paper is:
“The Saturation of the Infrared Absorption by Carbon Dioxide in the Atmosphere” by Dieter Schildknectht

I briefly scanned the DOE paper and there was no mention of the above paper.

CO2 Update
At the MLO in Hawaii, the concentration of CO2 in dry air is 429 ppmv. One cubic meter of this air has a mass of 1.29 kg and has mere 0.843 g of CO2 at STP.

         [v2]-[v1]/t=a

and you know what? There was very good agreement with the quadratic via Excel.

Somewhere along the line I heard that a sample size of 30 or more of variable data is likely to yield accuracy to 5 significant places. Was that the “T” Test? Having typed it down, uh five places really? I don’t remember (I have a 1944 DOB), That makes me going on 81.

Increasing sample size only allows a more precise calculation of the population average. It does *NOT* indicate whether the population average is accurate nor does it increase the accuracy of the population average.

This is also what is taught by blackboard statisticians – not physical scientists. To a blackboard statistician there is no such thing as measurement uncertainty which leads to the assumption that “numbers is just numbers”.

If the sample is made up of measurements then the data should be stated in the form of “estimated value +/- measurement uncertainty”. The measurement uncertainty determines the resolution of any subsequent calculations, including statistical descriptors like the “average”. There is no “5 significant places” unless the measurement uncertainty allows it. E.g. 10,999 mph +/- 50mph is poorly stated. Because of the measurement uncertainty you simply don’t know what the unit digit is. You barely know what the tens digit is. But a blackboard statistician will see no problem in this statement of velocity if the sample size is 100.

Somewhere along the line I heard that a sample size of 30 or more of variable data is likely to yield accuracy to 5 significant places. 

Reading a statistics site I bet. Using a sample size of 30 or more to characterize the “accuracy” of a mean value of a distribution requires dividing the standard deviation by the √30 (or whatever the sample size is) in order to estimate what the interval is where the mean may actually be. This is known as the experimental standard deviation of the mean.

One should first realize that a measurement is uncertain and should be expressed as an [“estimated point value” ±uncertainty]. In many cases, the mean of the population distribution of the ’30’ samples is considered to the “estimated point value” of the measurements. The standard deviation of the measurements is the usual calculation. When dividing the standard deviation by the √n, one is attempting to divine an interval surrounding the estimated point value (mean) where the true mean may lay. The more samples there are, the smaller that interval is. Thus one can assume the estimated point value is closer and closer to the population mean.

Here is the kicker, the measurement uncertainty is expressed as the standard deviation of the samples. This is because the dispersion of the measured values attributable to what you are measuring is the appropriate description of the range of values that are possible.

Ultimately the standard deviation and the standard deviation of the sample means are used to describe two entirely different things about a population distribution of values.

Reply to  Jim Gorman
July 31, 2025 11:42 am

The instruction manual for the TI SR-51A calculator offers a way to use n or n-1 weighting for calculating the standard deviation. As I recollect (it may be in Excel) the recommendation is to use n-1 weighting for less than 20 samples.

More importantly, for trying to increase the precision of measurements, one can minimize random errors by increasing the number of measurements. However, all the measurements must be of the same fixed value, measured with the same instrument, and the assumption is that the distribution of those measurements will be Gaussian to justify dividing by √n. Thus, taking 100 measurements will justify adding an additional significant figure to the calculated mean.

and it must be JUSTIFIED explicitly, not just assumed implicitly.

Thus, taking 100 measurements will justify adding an additional significant figure to the calculated mean.”

Not in the real world. You can’t even guarantee that when using actual physical measurement instruments that you will minimize the random errors with an increased sample size. Any measurement device using digital logic circuitry will have a “gray” area between what is considered a one and a zero. What the digital logic circuitry comes up with in such a case is not defined. It may be “random” but is not guaranteed to be Gaussian or even symmetric across readings. This is why it is absolutely necessary to understand the relationship between measurement resolution and significant digits. Even when calculating the mean from a large sample size you can’t add significant digits via averaging.



Reply to  Clyde Spencer

More importantly, for trying to increase the precision of measurements, one can minimize random errors by increasing the number of measurements.

Actually, increasing the number of measurements doesn’t minimize the randomness of the measurements. It adds more data to the sample means distribution surrounding the mean. Consequently, determination of the estimated mean has a reduced interval where the mean value lays. In other words, it reduces the uncertainty in the estimated mean point value and it is called the standard deviation of the sample mean.

It is important to use correct terminology also. Precision is actually an uncertainty interval that describes how well a given measuring device can provide the same value in repeated measurements of the same thing. Repeated measurements can only better define that category of uncertainty.

Resolution is another category of uncertainty that can not be increased by more measurements. A digital device is illustrative. If a device has two digits of resolution, that is all a final average of multiple readings can have. Calculating a mode for a distribution of measurements is illustrative. Assume a Gaussian distribution. The mean, mode and median should all be the same. The values in the distribution are in the tens and units digits. A mean can be 10.5. What can the median be? If I make an even number of measurements, let’s say I get 10.5. However, if I make an odd number of measurements I will have either 10 or 11. How about the mode? Will I ever get a mode that has a decimal value? This is important stuff in metrology but not so much to statisticians and mathematicians where numbers is numbers.

A way too many statisticians interpret the standard deviation of the sample means as the measurement uncertainty. It is not, it is only a statistic that can be used to illustrate how well the point value of the mean is known. There is still a dispersion (random error) in the actual measured values surrounding that mean. That dispersion is characterized by the standard deviation, a parameter that informs one of the uncertainty in any given measurand.

I don’t intend to criticize your post because I know you have a great appreciation for measurements and their uncertainty. I am using your post to maybe illustrate to other folks that this isn’t a matter of little importance. It can cause things like the Challenger Space Shuttle explosion or bridge failures or high rise building collapse. It can also cause the world to spend trillions of dollars on something that may not be occuring.

I think there are very clear lessons in how this has been handled for those in the UK seeking to unwind net zero. Employing a top credentialled red team to debunk the findings of the Climate Change Committee offers the best chance to cement a rational approach. Appoint them to replace the incumbents, and force the BBC to broadcast the outcome and the science behind it.

Some think that simply repealing the Climate Change Act would suffice. It doesn’t: their false narrative must be properly shown up before you attempt repeal.

Moreover, the actual process of unwinding net zero policies is complex. They rely on all manner of stand alone legislation, grid codes etc. and there are contracts and assets we have and assets we have no longer like coal fired power. Just unwinding the CCC doesn’t solve those. But undermining the carbon budgets and interim decarbonisation targets does halt the march in the wrong direction, and can be done with the Climate Change Act still in place.

But the far more important point is that from the very beginning, it should have been recognized that using pre-stabilized, time-step-iterated, large-grid, discrete-layer, parameter-tuned models to apply assumed “GHG” “forcing” scenarios would never have any diagnostic or prognostic authority.

It was a circular exercise all along, posing the models as having embodied knowledge already obtained! NO ONE KNEW, and NO ONE KNOWS NOW, that the end result of rising pCO2 must be to de-rate the longwave emitter to space, so as to require a warmer substrate (i.e. the land and ocean surfaces) to make up the difference.

So, in essence you are addressing is this.

An energy model with:

CO2 as input.
IR as transfer function
Temperature as output

Use mean earth radius, treating earth as a sphere.
Use 25 km grid and interpolate between lines.
Averaging temperatures.
Parameterize clouds.
Use mean earth orbit around the sun.
Sun is constant.
Fabricate bogus definitions of positive and negative feedbacks.
Treating a photon as a particle.
Redefining words such as thermalize.

About as bogus as they get.

And treating model outputs as data.
Input scenarios are experiments.

And this is the short list.

Scroll up and read my comments to JK. CO2 can’t cause recent any global warming because there is too little of it in the air and the CO2 absorption of out-gong IR light became saturated in 1920 at 300 ppmv.

Thank you. The image is really cool. However, it appears that the image is of the ocean. How much warm or hot air right at the surface is swept up by the wind? A sirocco is a hot wind that blows out from the desert.

Shown in chart (See below) from the late John Daly’s website are plots of temperatures at the Furnace Creek weather station in Death Valley. Note the plot for hot summer. This is my favorite weather station because it so remote and the temperature data has not been homogenized and adjusted (and pasteurized!)

I would like to see plot of the annual average temperature from 2002 to 2024, but I do not how to access the GISS data base, down load the data, and plots. If we get lucky and the plot stays flat, then we have empirical evidence that CO2 does not cause global warming. Suppose there is a slight linear rise in temperature. We might use the data to estimate the ECS.

no editorial oversight, no political vetting

The authors seemed to have enjoyed an awful lot of political vetting – no independent agency would ever believe that this who’s who of contrarians represents the leading experts in the fields covered by the report. In fact the authors seem hand-picked precisely because their views align with the politics of the current administration, not because of their scientific qualifications.

1 CO2 Is Not a Conventional Pollutant and Has Direct Environmental Benefits

The SC ruled that CO2 is unequivocally a pollutant under the terms of the Clean Air Act because it meaningfully endangers public health or welfare. Acknowledging that CO2 has benefits for plant growth does not negate the adverse effects from emitting mass quantities of it into the atmosphere very rapidly.

2 “Ocean Acidification” Fears Are Overblown

Yes, the oceans are still alkaline, they are becoming less so, i.e. they are becoming more acidic. This is just idiotic wordplay, no serious person views this as a legitimate scientific argument. The fact that life has evolved under different conditions than exist today does not mean that life is immune to changes in prevailing environmental conditions. This argument is a complete non-sequitur. The Great Barrier Reef is resilient but still in danger from environmental stressors. 2024 saw one of the largest coral bleaching events on record, the impacts of which were only partially captured in the 2023-2024 GBR surveys. The abundance of hard corals also does not necessarily signifiy that the reef ecosystem is in overall great health, as these fast-growing corals are particularly susceptible to bleaching events and other stressors.

3 Climate Models Consistently Overestimate Warming

Some, not most, models in CMIP6 show sensitivities above what scientists expect to be realistic, but overall models have been quite skillful at capturing surface warming trends. Organizations like the IPCC also do not simply rely on the total model spread, but on projections constrained by observations.

4 No Evidence for Increases in Most U.S. Extreme Weather

The IPCC AR6 explicitly reports medium to high confidence in observations of increases in weather extremes in North America, including heat extremes, precipitation extremes, and drought. But importantly, most of the most severe impacts of climate change are not expected to be acute for many years, some not even until the middle or end of the century. It’s not just about what we’ve seen, it’s about what we expect to see.

5 Sea Level Rise Is Not Accelerating Dangerously

The report conflates eustatic sea level with isostatic sea level. Globally, sea level rise is occurring and the rate is increasing over time. The rate of sea level rise during the 21st century has more than doubled relative to the rate during the 20th century. The US is as much at risk of this sea level rise as the rest of the world.

6 Attribution of Warming to CO2 Is Far Less Certain Than Claimed

Flagrantly untrue, the IPCC AR6 reports that the observed 20th century warming trend is unequivocally driven by anthropogenic CO2 emissions. There is no body of scientific research drawing any contrary conclusion.

7 The Social Cost of Carbon (SCC) Is Largely Arbitrary

The SCC is an economic estimate meant to guide policy by evaluating the potential future costs of carbon emissions. It’s a tool, not a forecast. Its utility or variability doesn’t diminish the physical science consensus on the severity of climate change, which is grounded in robust, independently validated research.

8 U.S. Emission Reductions Will Have Negligible Impact on Global Climate

While it’s true that US emissions alone represent only a portion of global totals, the argument overlooks two key points: first, cumulative global emissions determine climate outcomes, and US leadership can drive international cooperation and technological innovation; second, climate policy is not solely about immediate, detectable temperature changes but about reducing long-term risk, avoiding worst-case scenarios, and managing the economic and human costs of inaction. Framing the issue in terms of short-term detectability misrepresents how both climate systems and global policy mechanisms function.

The entire report is either misleading, incomplete, or flagrantly, inexcusably wrong. That such a document, written without any input from relevant subject matter experts (the idea that this handful of authors represent a depth of expertise across all of the domains this ranging report cover is beyond laughable), is being used to justify major regulatory dismantling by the EPA is abhorrent.

Claim: The report is “disinformation” and “cherry-picks” studies.

Pushback: The DOE report is authored by respected scientists with deep experience in climate modeling, attribution, and atmospheric science—many of whom have published widely in peer-reviewed journals. The report is overwhelmingly referenced, including citations from the very IPCC reports it critiques, and in fact spends entire chapters reviewing both sides of contested issues. The presence of extended quotations from mainstream literature, including detailed reviews of opposing arguments, refutes the idea that it is simply “cherry-picking.”

The claim that the DOE report cannot be “disinformation” or “cherry-picked” simply because it cites mainstream sources and includes some opposing views is misleading. Cherry-picking isn’t disproven by the presence of references, it’s defined by how selectively those references are used. A document can cite hundreds of studies and still misrepresent the weight of evidence by emphasizing outliers, outdated findings, or minority viewpoints while downplaying the broader scientific consensus. Just by presenting a “both sides have equally valid viewpoints” it reveals an inherent bias. The scientific literature does not reflect deep divisions over fundamental questions around the reality or severity of anthropogenic climate change.

Moreover, the breadth of the report, covering everything from atmospheric physics to economic modeling, raises serious questions about authorship. With only five listed authors, none of whom appear to be recognized leaders across all these domains, it’s implausible that the report meets the same level of expertise and peer scrutiny as the assessments it critiques, such as those from the IPCC or National Academies. Expertise matters, especially when drawing conclusions that contradict the overwhelming body of peer-reviewed science.

Just by presenting a “both sides have equally valid viewpoints” it reveals an inherent bias.

I would say that it reveals an objectivity and willingness to consider alternative hypotheses. Just by claiming that an open mind demonstrates bias, you demonstrate that you believe that ‘science’ is decided by ‘votes.’ That is, you implicitly believe that facts and logic have little weight in assigning veracity and that a hypothesis or paradigm is evaluated by how many scientists stand up when a journalist calls for a ‘division of the house’ and asks how many vote “Yes” on the correctness of a hypothesis.

“Weight of evidence” is a legal criteria, not a scientific one. As Einstein famously said, “Why 100? It takes only one to prove me wrong.”

Since you seem to be so impressed by credentials and don’t approve of only 5 providing their view on correctness, perhaps you would share with us your credentials and why you think that the readers here should accept your criticisms over the 5 that might serve as pre-publication peer reviewers, should you submit a paper for publication. That is, those of us who think that science should only be beholden to the facts, are being logically consistent when we speak on behalf of what we believe to be the facts. You, on the other hand, see the validity of a hypothesis as being a function of who, or how many scientists agree with you, as being the key to the truth. Therefore, we should know your qualifications for commenting, and know how many of the peers of THE five agree with you.

[ https://wattsupwiththat.com/2022/03/22/anthropogenic-co2-and-the-expected-results-from-eliminating-it/ ] It is only when the correlation, which is probably spurious, for the 1970s to present is smoothed, that there appears to be a correlation. Seasonally, there is an anti-correlation. The Law Dome ice cores strongly suggest that the causation is inverted for temperature and CO2.

I can’t find where the US climate zones have changed in recent history.

The analysis is garbage. The absence of a statistically significant difference does not constitute proof of equivalence. Further, the 1871 data were collected via bucket measurements over a brief 3-week transect using thermometers with limited accuracy, no documented calibration, and known cold biases, making them incomparable to modern, high-frequency, instrument-calibrated datasets. Averaging these sparse historical values and comparing them to multi-decadal modern records without correcting for sampling differences, seasonal timing, or spatial heterogeneity (e.g., depth, habitat type) introduces substantial noise and bias.

The analysis is therefore irrelevant to my ideas about climate change and the vulnerability of the GBR.

Yes, the oceans are still alkaline, they are becoming less so, i.e. they are becoming more acidic.

According to the online Encyclopedia Britannica, the inorganic chemistry definition of an acid is, “…, any substance that in watersolution tastes sour, changes the colour of certain indicators (e.g., reddens blue litmus paper), reacts with some metals (e.g., iron) to liberate hydrogen, reacts with bases to form salts, …”

Sea water does NOT exhibit those characteristics. Therefore, it is NOT a mineral acid. It is illogical and grammatically incorrect to claim one can have “more” of something that does not exist. It also does not acknowledge the strong (bi)carbonate and borate buffering in sea water that resists changes in pH.

Furthermore, the “becoming more acidic” phrase implies that there is a continuum from zero acidity to maximum. That is only true for a range of pH from <7 to about -1 or thereabouts. Another way of looking at it is that the behavior of a water solution depends on whether there is an excess of H3+ (hydronium ions) over OH1- (hydroxyl ions). In the pH range of natural sea water, hydroxyl ions are dominant. The ratio is OH1- > H3+. At a pH of 7, there are equal numbers; that is, they have a ratio of 1:1 and is called “neutral.” Actual acids have an excess of H3+ ions (i.e. H3+ > OH1-) and are therefore able to ‘donate’ a proton in a chemical reaction. The distinction between an acid, base, and salt is fundamental to inorganic chemistry.

Any movement toward the acidic end of the pH scale is called acidification, regardless of whether the substance crosses the neutral threshold. It’s the correct term used across peer-reviewed scientific literature and by every major oceanographic institution. I recommend you adopt the accepted terminology.

Cambridge dictionary: “the process of becoming an acid or the act of making something become an acid:”

Your definition is just one more corruption of language by climate science. Like you saying the term “climate change” doesn’t mean the climate has changed.

The process of making something become an acid involves movement toward the acidic end of the pH scale. Glad we’ve found common ground, bickering over semantics is such a massive waste of time when we already share a common understanding and there is zero confusion in the first place.

This is true only for environmentalists wishing to alarm people into believing that a problem exists. Physical scientists interested in technical accuracy do not call values that are less alkaline “more acidic”. The technical definitions of pH do not allow this.

Here is a link that explains the physical science description of pH. It is obvious you haven’t even had a high school chemistry class or you would know and use the proper technical terms.

pH – Basic (alkaline) vs. Acidic

Your use of pH is only a mechanism to sound “sciency”, similar to uneducated environmentalists. If you are going to use physical science terms, you should at least have the desire to do so accurately.

I could, but won’t bother to respond to all of your points. They read like alarmist propaganda, with little support for the claims.

However, consider this:

Michael Mann, the IPCC, and the rest of the Climate Catastrophe Industrial Complex will point to those authors and (rightly, more or less) proclaim them all to be heretics, climate deniers, climate skeptics, and nothing but a biased untrustworthy panel. Being backed by Trump will be all they need to tar it in the minds of true believers.

IANAL but I suspect the biggest benefit to this will be in the legal arena, especially backing up rescinding of the Endangerment Finding.

Anyone really interested in the climate issue should read the entire new report from the DOE. It isn’t hat long, only 100 pages of real materials (the rest is indexes, citation lists, usual blank pages etc).

The pdf is available here.

Not everyone here will love it, but it is a masterful document, very well put together.

I briefly scanned the report and found the following paper not mentioned:

https://arixiv.org/pdf/2004.00708v1 or https://arixv.org/abs/2004.00708
The title of the paper:
“The Saturation of the Infrared Absorption of Carbon Dioxide in the Atmosphere
by Dieter Schildknecht.

(cont’d from above)

He shows that when the concentration of CO2 in air reaches 300 ppmv, the absorption of out-going long wavelength IR light becomes saturated. In 1920 the concentration was ca. 300 ppmv in dry air was 300 ppmv. What this means that increasing the concentration of CO2 in air above this level will not result in a corresponding increase in temperature.  

Now go back to the start of this thread and read my responses to JK. Pay attention to refence to John Daly. At the MLO in Hawaii, the concentration of CO2 in dry air is 429 ppmv. One cubic meter of this air has a mass 1.29 kg and contains a mere 0.843 g of CO2. This trace amount of CO2 in air can absorb only small amount IR light which can heat up large mass of air by only a very small amount if at all. Please keep in mind that 71% of the earth’s surface is covered by H2O, the one and only the one greenhouse gas of importance.

It time to put an end to the IPCC’s Great CO2 Global Warming Fraud and Scam.

Unfortunately, we are way, way past debate on this issue. The Climate Liars long ago declared “the debate is over”. They knew that their lies would be called out, so invented their “consensus science” to shut down all debate, and simply called those who disagreed “Deniers”. This is war, and it looks like finally, the truth and actual science will win out over the lies.

Mr. 4: We all wonder, don’t we? I think they’re not, both post falsehood “supported” by biased, debunked source, but Mr. K goes for the “pal” insult in a NY minute, while Mr. J is more passive for awhile. In any event, they may not be bots, but what would they do different if they were??!! They must work AWFULLY cheap to compete with bots!

Which makes the point that the Connolly et at paper seems mathematically flawed.
This needs to be addressed or exchanged in the report
