Guest commentary from Nathan Lenssen (Colorado School of Mines)
A new analysis of historical temperatures suggests that things are getting warmer faster, but what does it mean for the future?

Koonin’s Continuing Calumnies
At a public event debating the DOE CWG report, Steve Koonin embarrasses himself further.

Our various graphics and model-observation comparisons have been updated with 2025 data. There are a few version updates that make some difference (particularly in sea ice extent), but the basic story is similar to last year. Feel free to comment and/or suggest changes for the future, including potential new comparisons.
DOE CWG Report “Moot”?
Somewhat breaking news. A court filing (from 9/4) from DOE has noted that the Climate Working Group has been disbanded (as of 9/3). This was done to make the EDF/UCS lawsuit moot, but it also means that DOE is withdrawing the report, no-one will respond appropriately to the comments submitted, and (possibly) it becomes irrelevant for the EPA reconsideration of the Endangerment Finding.
What a farce.
Update: Via Andy Revkin, the EDF/UCS’s blistering response to the DOE filing. Pass the popcorn.
Climate Scientists response to DOE report
As we’ve mentioned, Andrew Dessler and Robert Kopp have been coordinating a scientific peer review of the DOW ‘CWG’ Critique of Climate Science. It is now out.

The first somewhat comprehensive reviews of the DOE critical review are now coming online.

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.

In honor of the revelation today, that Koonin, Christy and Spencer have been made Special Government Employees at the Dept. of Energy, we present a quick round up of our commentary on the caliber of their arguments we’ve posted here over the last decade or so.
TL;DR? The arguments are not very good.

Over multiple generations of CMIP models Arctic sea ice trend predictions have gone from much too stable to about right. Why?

One more dot on the graphs for our annual model-observations comparisons updates. Given how extraordinary the last two years have been, there are a few highlights to note.
