In the Rocky Mountains, spring-fed streams and ponds have vanished, leaving patches of cracked mud. This year has been so extremely warm and arid that the mountains have remained largely snowless. The source of the Colorado River is drying up. @rgauth999.bsky.social www.latimes.com/environment/...

For centuries, the farmer’s almanac gave people a way to ask simple questions about future climate: what should I expect, and how should I prepare? But what if you could build an almanac on real physics simulations and steer it to any scenario, extreme, or decade you care about?

What *actually* works — right here, right now — to address climate change? Here you go. This is the result of thousands of hours of painstaking research and analysis from the Project Drawdown team.

🌎⚡ A frontier (1.5°, 15-day) ensemble weather forecast in ~3 seconds, from a probabilistic model you can train in ~1 day on a single H200 GPU?* Meet U-Cast, our new #ICML2026 paper. 🧵

Check out this thoughtful article about AI weather forecasting from @fastcompany.com! A privilege to be quoted alongside several colleagues whose work I admire and grateful to the authors for shining a light on some of NVIDIA's work in this space. www.fastcompany.com/91548095/ai-...

Really enjoyed talking to @drshepherd2013.bsky.social to discuss Earth system modeling, AI weather forecasting, and how GPUs are helping researchers model climate at greater scale and resolution. Check out this Weather Geeks podcast on where computing and climate science intersect! t.co/PD9IBJnn8E

At this point, solving climate change is cheaper than not solving it -- not only on some grand 50 year time horizon, but tomorrow, today, immediately. Soving climate change *is* affordability. Maybe Dems should tell voters about that.

A toll on the Strait of Hormuz isn’t technically a carbon tax, but ... it still kind of is? @robinsonmeyer.bsky.social does the math of what Trump’s latest astounding act of climate policy means: heatmap.news/energy/trump...

I am getting a lot of questions about whether Trump's threats alone are illegal. The answer is yes. 1. First, Additional Protocol I states “Acts or threats of violence the primary purpose of which is to spread terror among the civilian population are prohibited.” (also DOD LOW Manual §5.2.2) 1/

They are complementary. There are essentially 0 drugs approved that didn't rely on NIH R&D. But NIH funding alone cannot deliver drugs, because NIH funding discovers new biology, but pharma R&D discovers the actual **drugs** (small molecule, monoclonal antibody) that modulates the biology.

i don't really know about other industries, but with software i have got to say that refusal to use ai at any place in development is acceptance of inability to compete. at the same time, refusal to maintain standards and quality through manual work is also acceptance of inability to compete.

Announcing a deal to pay $1 billion to stop two wind farms, Interior Secretary Doug Burgum said: “The era of taxpayers subsidizing unreliable, unsecure energy is officially over.” Hours later, a massive American oil refinery accidentally exploded, spiking gas prices nationwide

The war in Iran has hit Americans at the pump. It’s another reason to turn to renewable energy. www.newyorker.com/news/the-led...

Honestly, this historic heat dome across the West is really hard to put into words for me. Temperatures over 110°F (43°C) in March, shattering all-time monthly records on multiple consecutive days, and not just by a little. ➡️ I can confirm this is human-caused climate change. polarwx.com/models/

Nature polled ~1,200 scientists and found 46% had a second income during their PhD. 59% said economic anxiety would push them toward a side hustle. Stipends in the US, UK, and Canada are at or below the poverty line in expensive cities www.nature.com/articles/d41...

ICML requires authors to serve as reviewers. Reviewers aren't supposed to use LLMs (with caveats 🧵). ICML used prompt injection to catch reviewers using LLMs. And now they have desk rejected the papers submitted by those reviewers. What a mess...

Utilities are convincing lawmakers around the U.S. to delay bills that would allow people to buy solar panels, plug them into an outlet and begin generating electricity. n.pr/4ul3y2p

As a rare climate scientist working in Silicon Valley, I've been drinking from the AI firehose a lot more than my peers. I thought it would be helpful to lay out my experiences of both the promise and pitfalls of using AI to accelerate scientific research:

I am running a Climate Dynamics reading group for UCI graduate students this Spring and would like to propose a list of accessible papers on "big ideas" in climate dynamics from the 21st Century, prioritizing primary sources over review papers. Any suggestions of papers? (Self-promotion welcome!)

In January, @anishathalye.bsky.social, @josejg.bsky.social, and I returned to @csail.mit.edu to teach Missing Semester, a class on topics we miss from most CS programs—tools and techniques that everyone should know, like Bash, Git, CI, and AI tools. Today, we’re releasing the course for free online!

The leaders of seven states failed to negotiate a deal to share the diminishing waters of the Colorado River by a Trump administration deadline, leaving the Southwest in a quagmire while the river’s depleted reservoirs continue to decline. www.latimes.com/environment/... @latimes.com

"The Trump administration and its well-funded allies in the fossil fuel industry are blocking our ability to put the cheapest, most reliable energy onto the grid." heatmap.news/ideas/trump-...

The scientific understanding of human-driven climate change is much stronger today than it was in 2009 when the EPA first issued the endangerment finding. There is no scientific basis for the Trump administration's decision to repeal it

This is such a fascinating blog post and project!

Here is one of the dumbest things about vibe coding that I don't see a lot of people talking about Imagine you're an open source maintainer and someone opens up a pull request against your repository that they vibe coded. They may or may not tell you they vibe coded it; it doesn't really matter… 🧵

Bridging Physics & AI in Climate Modeling 🌍🤖 Introducing JCM v1.0: A fully differentiable, intermediate-complexity atmospheric model built in Python/JAX. Training hybrid models is hard because legacy code lacks gradients. JCM solves this.

NCAR represents what is possible when a nation chooses to invest in science as a public good, writes @carlonimbus.bsky.social of @ucs.org. #SaveNCAR eos.org/opinions/wha...

Your regular reminder that when folks say "its cold outside where I live, what happened to global warming?" that the world is big, and weather still exists.

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.

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

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/...

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
