Unforced variations: Feb 2026

1 Feb 2026 by group 165 Comments

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.

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.

This month’s open thread. As usual try to remain substantive and avoid insults and personal attacks on other commenters. Any sock-puppetry or abusive comments will just be deleted on sight. Also, please don’t outsource your comments to ChatGPT – cut-and-pastes of long-winded LLM output are tedious and add precisely nothing to the conversation. There are real things happening in climate – please focus on them.

Unforced Variations: Aug 2025

This month’s open thread. Please try and stay focused on substance rather than personalities. There are many real issues that are particularly salient this month, and so maybe we can collectively try not to have the comments descend into tedium.

Note: Moderation will be applied to over-frequent and pointless commenters (you know who you are, and no, we don’t care to argue about it).
