NEW PAPER: In a new paper, jointly published in @agu.org Earth's Future & @ametsoc.org BAMS, and co-led by Melissa Kenney, @costasamaras.com and me, 175 authors outline priorities to guide the future of scientific assessments of climate change in the United States. 🧵

📣 The review of the First Order Draft of the Working Group II contribution to IPCC’s Seventh Assessment Report on impacts, adaptation and vulnerability has started. Interested experts can register until 20 Nov 2026: https://bit.ly/4y1LI58 The review ends on 4 December.

Great thread (read the whole thing here or on his blog), but this is one of my favorite insights from Cory over the years. " You mustn't be afraid to dream a little bigger, darling." - Eames Inception

I don't know that there is a definitive line to cross that makes you say, "I live in a police state now" but when masked gunmen can routinely brutalize the public, citizen or immigrant alike, with impunity, you have reached that point.

A 2025 Nobel Prize winner in chemistry, Omar Yaghi is the son of Palestinian refugees who grew up in Jordan. He just left the US to move to China after raising concerns about rising anti-immigrant sentiment, like the kind shown here. donmoynihan.substack.com/p/china-than...

0.1C of warming is ~222 gigatonnes of co2 now into perpetuity. Let's say now to 2100; just under 3 GT CO2/yr. Brazil's land-use emissions were up around this not long ago! Ambitious number but totally feasible, imo carbonimpactstracer.com#interactive-... climateactiontracker.org/countries/br...

AOC: "As AI begins to encroach in our society, their goal is to take your cognition away from you. AI's goal is to take your thoughts away from you, your ability to think away from you, so that you become dependent on a machine ... reading books is active resistance"

Science is inherently political and when our government is actively hostile to science as a whole, publications should be able to write about it without being censored. Alas. www.thenation.com/article/soci...

Likely the most important thing I've ever written — if you're an academic and the AI mania unsettles you, here's my best shot at presenting some intellectual tools that might help you articulate why. arxiv.org/abs/2610.27251

Brian Stone, acting head of the National Science Foundation (NSF), is retiring at the end of the year, along with chief of staff Rebecca Keiser. 😐

Why have countries been pushing for a vital global climate report to be delayed?

#IPCC65 The Panel was unable to reach agreement on either the timeline or the budget for the Seventh Assessment Report cycle, forcing a suspension of the meeting and raising alarm among #IPCC authors. Read the summary: enb.iisd.org/intergovernm...

Authors, There is a massive surge in AI-generated scams from people impersonating podcasters or reviewers or marketers offering to promote or boost books. For a fee. Then they disappear. Often from a Gmail account. I know we all want our books to be better promoted, but don't fall for these scams.

Exhibit A: www.kuow.org/technology/2...

Sunrise's "pivot to saving democracy as the first step towards saving the planet seems like a smarter move every day. Climate organizations should be broadening their scope to include fighting fascism," not "encouraging activists to put away the idea of linking climate with other justice movements"

NIH demanded I censor my science by cutting terms including “climate", “carbon”, “climate change” and reframing my science using Gov-favored words.  10/

4 MONTHS later on the *1 YEAR ANNIVERSARY* of when US Gov first terminated my NIH Director’s award, I received an email gut punch. NIH determined my grant was “out of alignment with the NIH’s priorities due to its focus on overall effects of carbon emissions and climate change on human behavior.” 8/

Together with other scientists I’m suing the 🇺🇸 US National Institutes of Health for violating our 1st Amendment rights & censoring our health science. I’m ready to shine a light on the darkest days. Buckle up, read on. This gets pretty wild… THREAD

The 65th Plenary session of IPCC was suspended because the negotiations were going overtime & most small delegations from developing countries (incl. LDCs, SIDS) had to leave on Friday evening. A "plenary" decision taken during the week-end without them would not have been inclusive or fair.

"Several [IPCC] Panel members from least developed countries and small island developing states expressed concern that some calls for inclusivity were in fact being used to delay the very actions that the most vulnerable countries urgently need." enb.iisd.org/intergovernm... #IPCC #timeline

Full obstruction : no agreement on budget and timeline for #IPCC AR7

Great seeing @leahstokes.bsky.social at Rutgers today! (Clearly we’re not good at social media or we would have gotten a photo)

impossible, I'm quite certain we put our top genius on this problem

After contentious deliberations throughout the week, #IPCC65 has failed to reach agreement on either a timeline for the working group reports or a budget for the coming year. IPCC Chair Jim Skea has suspended the session and says it will be resumed at a future date. #AR7 @ipcc.bsky.social

Michael Roth is a mensch on many counts

Seizing the passport, phones, and computer of an opposition lawmaker is straight-up authoritarianism. There is no other way to describe it. www.wsj.com/politics/pol...

Ho boy, do I have a story for you. The question of how ice breaks has been central to glaciology for well over a century.
