On Thursday, the Environmental Protection Agency reversed its “endangerment finding," which found that greenhouse gases are a threat to human health.

@andrewdessler.com

I've been getting a lot of requests from reporters for comments about the removal of the DOE Climate Working Group report from the EPA's repeal of the endangerment finding.

Here are some comments:

The EPA's decision not to rely on the DOE Climate Working Group report for the Endangerment Finding repeal is appropriate. The report’s fundamental flaws make it unsuitable as a basis for policy decisions.
The report demonstrates systematic methodological failures. It relies heavily on cherry-picked studies while omitting contrary evidence from the peer-reviewed literature. Key findings are presented in ways that misrepresent what the underlying research actually shows. These are not minor errors—they are the kinds of problems that would render a scientific analysis indefensible in any rigorous review process, including judicial review.
The process itself also failed to meet basic scientific standards. The report was not peer reviewed and certainly appears to be working backward from a pre-determined conclusion. The DOE received substantial public comments challenging the report’s conclusions after the public release but never responded to them. A credible scientific assessment requires engagement with contrary evidence and criticism, not silence.
Notably, the Climate Working Group’s membership are the cream of the crop of climate contrarians. The DOE report therefore represents the best case against mainstream science. That they produced a report that is so lacking in credibility actually demonstrates how strong mainstream climate science actually is.

I also have often made this observation stated below: the arguments of the deniers of human-caused climate change are so poor, so easily refuted, and intended only for gullible lay people, that they basically prove how strong and compelling the evidence for human-caused climate change really is.

Make this make sense. (Trick question; you can’t. Hint - the EPA is a Federal agency.)

“The final rule announced on Thursday argues that the 1970 Clean Air Act applies only to direct, localized pollution, whereas greenhouse gases spread far and wide and therefore aren’t subject to regulation.”
