This month’s open thread about climate topics. Try to be substantive and respectful to other commenters.
Note: Comments that are abusive and/or repetitive to the point of tedium will be moderated. If you’ve made the same point ten times already in the thread, and people are still arguing with you, repeating it another ten times isn’t going to help.
2025 Updates
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.
A peek behind the curtain…
New email releases from the EDF/UCS lawsuit against the DOE provide a rarely-seen behind the curtain look at how the climate contrarians work.

There has been a frenzy around artificial intelligence and deep machine learning (AI/ML) since the “ChatGPT Moment” in 2022, and AI/ML is for sure going to affect us all. It strikes me that this buzz also looks more like a science fiction story (utopy/dystopy) than the old-fashion Clondyke goldrush craze.

This month’s open thread. We’re not great ones for New Year’s resolutions, but let’s try. How about we resolve to stay substantive, refrain from abusing one another, and maintaining a generosity of spirit when interacting with others?
Lots of things get updated in January and we’ll try and keep up, though possibly with less fanfare than in previous years. In other news, we await the (supposedly imminent) release of a new “National Climate Assessment”, and the (supposedly imminent) engagement of the authors of the DOE ‘climate report’ with the extensive critiques they received. Meanwhile CMIP7 has started, and we expect results to trickle into the databases throughout the year – dig into some of the literature to get a sense of what will change (better models, improved forcings, etc.).
Eppure si riscaldi.
1.5ºC and all that
The Paris Agreement temperature limits are a little ambiguous and knowing where we are is tricky.

Who should pay?
Climate risk scores on real estate listings are having an impact on prices and realtors are complaining. But who should pay for these losses?

Hi folks, just a quick maintenance notice to say that we are upgrading the blog to a more recent version of PHP (which is the code that underlies WordPress) (going from version 7.4 to 8.3). Unfortunately, this has caused problems for two of the older plugins we use, Kcite (which provides the inline links to the references from the DOI code), and Language Switcher (which we used a lot at the beginning to provide translations). Neither are actively maintained by their original coders (and we have updated some of the functionality in any case).
As of today, we’ve had to turn them off – and so the reference lists are not being generated and the languages on older posts will mixed up. If any of our readers have some relevant skill sets, we’d be happy to work with them to debug this issue! Let us know in the comments. Additionally, feel free to make suggestions for other improvements – the more specific the better!
Hopefully, we will resolve the issues soon. Thanks for your continued support and patience.
Update (Nov 28): I got the Kcite plugin working again (follow the link for details and remaining issues).
