This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again. www.nature.com/immersive/d4...

Trump says US needs Greenland to protect Greenland from Russia. That is probably not in the top 100 national security threats we face. It is not a threat I have once ever heard mentioned, until now.

Donald Trump is unfit to lead and clearly out of control. Invoke the 25th Amendment.

The US is collapsing into fascism and going to war with Europe and the opposition party is like “I’m here to talk about the important thing: how your average grocery bill has risen by two dollars over the last year, which I also have no plan or ability to fix”

For some reason, very few people these days will stand up and say it, but: the US federal bureaucracy is one of the great wonders of the world, staffed with incredibly diligent people who do their jobs well and care deeply. Trump's destruction of the federal apparaus was a historic crime.

This makes sense to me.

This is a HUGE win…and one that happened because we ~collectively~ said “NO!” But AAAS coming in and saying on record to the NYT “Science is doing ok. Things are not bad at all…” is baffling. If things are hard for you as a scientist, please share in the comments. www.nytimes.com/2026/01/10/s...

THREAD The first full year of tracking research on @bsky.app Hi, we are Altmetric, and we track how research is communicated across the web. We now have one full calendar year of Bluesky research data and thought we'd have a looksie.

On the 5th Anniversary of the failed January 6th insurrection attempt, we’re reminded how fragile democracy can be. We must remember the darkness of that day so it’s never repeated. As history is rewritten by some, we choose to speak the truth of what happened.

It’s almost like green energy is the only way forward and a handful of oil barons are doing everything in their power to keep that from happening so they can get even richer at the cost of literally everything else in the world.

Every heat pump, solar installation, battery, EV weakens the Oil industry hold on the economy and on our politics.

I’m excited to share Review, a bookmarklet that makes it easier for you to code review AI coding agents. The bookmarklet turns all unresolved comments on a GitHub pull request into a Markdown-formatted text blob that you can paste into your coding agent of choice. marcua.net/minitools/re...

this X post is worded like an indictment of Bluesky, but it’s actually a perfect example of why Bluesky is *better* than X — users can’t create their own shit on X when they don’t like what X is doing

This is potentially a massive cover-up. Where is the corporate-owned legacy media that claims it exists to expose government corruption? www.democracydocket.com/news-alerts/...

There are many claims that AI is a “planet killing” source of greenhouse gases. But is it? This paper might be the most detailed estimate of the emissions associated with AI. It suggests that AI could emit as much as 30-80 *million* tons of CO2 per year. www.cell.com/patterns/ful...

#AGU25 folks, there is a rapid- response town hall TODAY on the #NCAR dismantling at 1 pm, La Nouvelle Orleans ballroom C (per an AGU media advisory)

A deeply dangerous — and blatantly retaliatory action against Colorado — by the Trump administration. NCAR is one of the most renowned scientific facilities in the WORLD — where scientists perform cutting-edge research everyday. We will fight this reckless directive with every legal tool we have.

The time to act to stop the dismantling of NCAR is now. Here's a template if you'd like to write to your representative.

Based on what I have been hearing about the NCAR situation, no one knew anything until the USA Today article came out. That means there isn’t much actual organization inside the administration to pull this off and a chance to fight back. Call your congresspeople today! Especially republicans.

Turns out climate change keeps happening even when we decide we don't want to talk about it anymore www.theguardian.com/world/2025/d...

The good news? Nearly all the world’s advanced economies are now *cutting* their emissions, while still growing their economies. (It had little to do with the Paris agreement per se, though. It was due to better technology.) The bad news? We need to much more. www.theguardian.com/environment/...

With hundreds of satellites launched each year and thousands more planned, scientists are increasingly concerned about the emissions from rocket launches and from satellites burning up upon returning to Earth.

We tested one of the most common prompting techniques: giving the AI a persona to make it more accurate We found that telling the AI "you are a great physicist" doesn't make it significantly more accurate at answering physics questions, nor does "you are a lawyer" make it worse.

If anyone cares at all, EV battery recycling is now hitting 99% recovery for important metals Please remind me again what the recycle rate for fossil fuels is interestingengineering.com/energy/recyc...

Creating a $50,000 Kaggle competition to accelerate hybrid physics-ML climate modeling is one thing. Testing the competition-winning ideas inside a climate model is another. We went end-to-end and finally have a write-up showcasing the results. @kaggle.com @leapstc.bsky.social

Recently gave a @leapstc.bsky.social lecture at Columbia and at UCLA on a question I’m excited about: How can we design diffusion models for scientific inference—uncertainty-aware, calibrated, steerable, and heavy-tailed? www.youtube.com/watch?v=QeLZ...

The United States is safer and stronger when democracies like Ukraine are free, stable, and strong enough to deter our adversaries. The deal President Trump is forcing on Ukraine calls on Ukraine and NATO allies to make major concessions or risk losing American support.

One of the most egregious tactics used by the reactionary right is to pretend that progressive NGOs with miniscule budgets have an iron grip on governments globally, while the lobby groups funded by fossil capital are powerless smol beans.

I wanted to offer some thoughts on the Gates climate memo that has been circulating this week. While I can't directly speak for others, I can say that my own response is one of dismay & deep frustration (and that this view is shared by many climate/Earth scientists). [1/n]

Well reported story on the PBS News Hour about science cuts and the ongoing and potential brain drain. www.youtube.com/watch?v=yLvO... Thanks to Terrance Tao and other scientists at various career stages for having the courage to speak out. Watch and share! 1/7

Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

News that shocks no one: Carbon offsets do nothing for climate.

Purchased a hard copy of the US constitution in Lexington, MA today. Given all the crazy stuff that’s happening in the world, it feels strangely comforting to own a copy that I know no one can change.

We have exciting news! #CI2026 will be hosted by the École Polytechnique Fédérale de Lausanne (EPFL), in the period of April 27-30, 2026. More information in Tom Beucler's post: www.linkedin.com/posts/tom-be...

New paper out. In which we helped the folks at the Allen Institute for AI (AI2) show that their climate emulator does a good (though not perfect) job at reproducing E3SMs' response to different SST boundary conditions. 1/ agupubs.onlinelibrary.wiley.com/doi/full/10....

David Wallace-Wells is the best climate journalist working today, arguably the best journalist period, and this is a fantastic summary of where things stand on climate change:

Our democracy is not self-executing. It depends on us all as citizens, regardless of our political affiliations, to stand up and fight for the core values that have made this country the envy of the world.
