The Endangerment of the Endangerment Finding?

29 Jul 2025 by group 177 Comments

The EPA, along with the “Climate Working Group” (CWG) 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.

Here are some relevant links:

  • Original Endangerment Finding (2009)
  • Proposed rule (2025)
  • DOE Critical Review of Impacts of GHG Emissions on the US Climate (Christy, Curry, Koonin, McKitrick, Spencer, 2025)

This is a placeholder post for links and comments while folks try and digest the details. Feel free to post links to analyses as you find them and we’ll elevate the best to the OP. We’ll have a more considered response in a couple of days.

Updates (7/31):

Some relevant media reports:

  • “Contrarian Climate Assessment from US Govt. draws swift pushback” Science
  • “Trump’s EPA takes aim at the Endangerment Finding” Scientific American
  • “Scientists Say New Government Climate Report Twists Their Work” Wired
  • “DOE reframes climate consensus as a debate” E&E News

A self-justifying rationale for the CWG effort from Judith Curry. Note that she (somewhat incredibly) will not opine (publicly) on the Endangerment Finding itself. Stealth advocacy anyone?

Links for the public comments:

  • On the EPA proposed rule: The Docket is here (but see above link on how to submit)
  • On the DOE ‘Critical’ Review: (Instructions). Docket should be here, but is not yet live.

Note that It is not clear to us that comments on the DOE report will have any direct role in the EPA ruling.

    Given the framing of the Administration’s environmental & energy policy as a quasi-religious crusade, as when EPA Administrator Zeldin spoke last week of :

    ” driving a dagger through the heart of climate-change religion and ushering in America’s Golden Age.”

    one should note that he and the President are making verbatim quotes from the Cornwall Alliance and the Realist Catholic Climate Declaration issued a decade ago, and since revived by John Droz in the the K through 12 educational program of the CO2 Coalition

    This placeholder was for links and discussion while folks “digested the details.” We were told a more considered response would follow in a few days.

    Nine days later: silence.
    Looks more like a ‘chicken little’ beat-up than anything of substance — and clearly of little interest to the broader public and the media.

    Let’s be honest about where things stand. The EPA will do what it intends to do. It doesn’t care what’s said here, on Bluesky, or by frustrated celebrity scientists. It will process the public comments, then rescind the Endangerment Finding and revise emissions regulations accordingly. Biden’s EV and RE grants will be quietly unwound.

    The EPA has never been a scientific body, and the Clean Air Act was never designed to regulate greenhouse gases. What’s coming is a political decision under partisan pressure — just like in 2009.

    Another chapter in America’s long experiment with dysfunction.

    Argue among yourselves, if that helps.

    Wonder if page seven, 2.2.2 will get an update for the following out today from the Australian Institute of Marine Science:

    “World’s biggest coral survey confirms sharp decline in Great Barrier Reef after heatwave”
