Pielke Jr. –A Takeover of the IPCC

by C. Rotter, Aug 24, 2025 in WUWT

Roger Pielke Jr.’s “A Takeover of the IPCC” offers a timely post-mortem on what’s left of scientific rigor in the world’s most influential climate assessment body, of which Pielke Jr. has long been a supporter. The article chronicles not just a change in personnel at the IPCC, but a seismic shift in methodology and purpose—a transformation best described as a hostile takeover by advocates of “Extreme Event Attribution” (EEA). The implications for public policy, scientific integrity, and even the basic credibility of climate science are staggering, and long overdue for public scrutiny.

Pielke’s article, in short, is a wakeup call. The so-called “settled science” is more unsettled than ever, and the very structures meant to provide honest assessment are being repurposed for advocacy. The cost, inevitably, will be paid in public trust, misallocated resources, and a continued failure to address the real drivers of disaster risk.

There’s an old saying in science: extraordinary claims require extraordinary evidence. The new IPCC, sadly, seems content to settle for extraordinary press releases. The public deserves better. It’s time to ask, loudly, whose interests are really being served by this shift—and to demand a return to genuine scientific skepticism before the last shreds of credibility are gone for good.

Michael Mann’s Social Media Rants Turn Anger Into Alienation

by R. Bradley Jr.,  Aug 23, 2025 in ClimateChangeDispatch 

Michael “ClimateGate” Mann cannot get out of his own way.

His arrogant, condescending social tweets speak for themselves—just as the words, sentences, and paragraphs of the East Anglia emails did. [some emphasis, links added]

“And yes, there is empirical, peer-reviewed support for the conclusion that climate deniers, in general, are truly awful human beings.” (–Michael Mann, via X)

He is not the kind of person you would want in just about any endeavor, much less as a climate scientist trying to present a case.

This post traces Mann’s angst on X and then at BlueSky, his successor to X:

Final Comment

This is enough to keep a psychologist busy. Mann stepped into his own manhole, and he kept digging down.

Like Al Gore, he hurts his cause more than he helps it, as 97 percent of his colleagues (just an estimate) are more rational and quieter than he is on the same subject.

Another Study Affirms Anthropogenic CO2 Does Not Drive Climate Change

by K. Richard, Aug 22, 2025 in NoTricksZone 

Utilizing AI’s evidence-streamlining capabilities, a new study (with “Grok” literally positioned as the lead author) summarizes a few of the key counterpoints undermining the CO2-drives-climate narrative.

For example, consider that humans contribute just 10 GtC per year to the carbon cycle, whereas nature’s sources (ocean outgassing and soil respiration, primarily) contribute 220 GtC annually. The combined total (230 GtC/year) does not distinguish between sources, and thus natural sinks that remove carbon from the atmosphere proportionately absorb human as well as natural emissions, with the human percentage (4%) insignificant and the natural predominant (96%).

But even if the last century of rising CO2 was 100% anthropogenic, the empirical data indicate the residence time for atmospheric CO2 is just 3-7 years. This necessarily precludes the possibility for anthropogenic CO2 in particular to be the driver of presumed radiation imbalances, or radiative forcing. This is because the tiny anthropogenic component is too quickly removed from the cycle to have more than a negligible impact. Nearly 90% of CO2 derived from human emissions sources since 1750 has already been removed, absolving humans of the alleged responsibility for (allegedly CO2-induced) climate change.

The atmospheric CO2 residence time would need to last centuries for the presumed effects of anthropogenic CO2 to have the dominant impact the UN’s Intergovernmental Panel on Climate Change (IPCC) claims it has. So what has the IPCC decided to do? Of course, the IPCC (and those hoping to blame humans for climate change) rely on modeled assumptions that the atmospheric CO2 residence time is, yes, over 100 years. There is no empirical basis validating these assumptions. To put it crudely, the IPCC’s 100-year CO2 residence time model is made up. Fake.

The study also addresses the causality problem that the CO2-drives-temperature narrative has, as there are many studies affirming CO2 changes follow, rather than lead, temperature changes. This T→CO2 directionality is not only observed in the short-term (months), but in paleoclimate studies (an 800-year CO2 lag) as well.

In sum, there is ample evidence available to support the conclusion anthropogenic CO2 does not drive climate change.
