This month’s open thread on climate topics. The annual ranking horse race is in full swing, discussions of extreme weather abound, Arctic sea ice is reaching it’s annual minimum, and the future of evidence-based policy making seems dim. Oh well.
This new El Niño is different

There is a new El Niño out there and it was officially declared already on June 11 by NOAA. This is both unusually early in the year and very soon since the last El Niño in 2023-24.

It was allegedly the largest scientific conference on the Faroe islands ever, as it was combined with the Oceans Connectivity Conference.

Scenarios, schmenarios…
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…
