“The Arctic Council is not dead”

30 May 2026 by rasmus 12 Comments

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 wide-ranging diversity of course coloured the congress. It was allegedly the largest scientific conference on the Faroe islands ever, as it was combined with the Oceans Connectivity Conference.

Scenarios, schmenarios…

20 May 2026 by Gavin 65 Comments

The fantasy version of the normal updating of scenarios for a new round of CMIP simulations doing the rounds is bad faith BS.

This month’s open thread on climate topics. El Niño coming (shades of 2023), competitive predictions, ill-advised geo-engineering ideas, and massive shifts in renewable energy roll out. Surely something there to discuss…

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

A reflection on reflection

13 Apr 2026 by Gavin 242 Comments

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.

Spencer’s Shenanigans: Part II

4 Apr 2026 by Gavin 45 Comments

We previously highlighted Roy Spencer’s poor practices in comparing models with observations, but we’ve now dug down a little deeper, and it’s not pretty.

The Puzzling Pleistocene

18 Mar 2026 by Gavin

The mystery of why the last million or so years of glacial variability are so different to what came before just got more mysterious…

How robust is our accelerometer?

8 Mar 2026 by group

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?
