Here we go again. An obscure, methodologically poor, paper published with little to no review makes a convenient point and gets elevated into supposedly ‘blockbusting’ science by the merchants of bullshit, sorry, doubt. Actual scientists drop everything to respond, but not before the (convenient) nonsense has spread widely. Rebuttals are written and submitted, but by the time they are published everyone has moved on.

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.

Some intriguing new measurements of salinity in the oceans around Antarctica have set off reams of sensationalist speculations. Maybe some context is helpful…

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?

The WMO released its (now) annual state of the climate report this week. As well as the (now) standard set of graphs related to increasing greenhouse gas concentrations, rising temperatures, reducing glacier mass, etc., Zeke Hausfather and I wrote up a short synthesis on the contributions to recent temperature anomalies.

Comparison Update 2024
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.
