RealClimate: At a public event debating the DOE CWG report, Steve Koonin embarrasses himself further. This week there was a bit of a peculiar event at the Civitas Institute at Texas A&M, with three of the CWG authors (John Christy, Steve Koonin and Ross McKitrick) being rebutted by Andy Dessler (working solo). The event itself was

RealClimate: For the first time, the Federal Judicial Center (FJC) commissioned a chapter on climate science for the manual they put out (with the NASEM) for judges, the Reference on Scientific Evidence (4th Edition).

A few weeks ago, the email exchanges of the CWG authors were published after a court ordered them to be made public. In them, there is an interesting exchange between Steve

Confirmation bias and a profound lack of curiosity mark the latest ABC (Anything But Carbon) contrapalooza in DC this week and a decade-old albedo error trips them up.

RealClimate: Somewhat belated open thread for this month! (Oops). Please stick to climate related topics, and remain respectful.

RealClimate: The fantasy version of the normal updating of scenarios for a new round of CMIP simulations doing the rounds is bad faith BS. As climate folk will know, the community is currently embarking on a new round of climate model simulations to support analyses and projections for the next IPCC report (due in 2028/9). This

RealClimate: The 4th UArctic congress on the Faroe islands finished with the message that the Arctic Council is still alive. It has overcome recent setbacks with difficulties concerning two of its member states, Russia and the US. The Arctic Council represents 8 nations together with indigenous peoples and has observers from around the world, and this
