OK, this is wild. In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them. It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*. What the HELL? 1/

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:

@climatebook.bsky.social once called climate change, “humanity’s final exam” and it turns out we’re failing the non-graded survey the instructor gives on the first day of class to make sure students know how to add some numbers together.

Last December, weather and climate scientists sat down with us to tell us why they loved the National Center for Atmospheric Research, and why it benefits us all. Last night, the NSF began dismantling it. Listen to what they have to say, and why it's urgent that we #SaveNCAR wclivestream.com/act

Does anyone have experience talking about science at a comedy club? Seems like I will and would love some climate/planetary related things that could be good for that setting cc @drkatemarvel.bsky.social @climateofgavin.bsky.social

At some point we need to be stronger with the language of just calling all these people frauds. In any case, flawed analysis aside, no one seriously thinks the highest sensitivity cmip6 models should be the basis for decarbonization and economic destruction.

Indeed, though it’s good to be well calibrated in one’s despair.

A Minnesota woman observing ICE agents in her car was cornered on one-way streets. An agent approached, called her by name—citing facial recognition. Days later, her Global Entry and TSA privileges were revoked, with no explanation.

NASA needs to follow suit.

Domestic terrorism

Meanwhile…

The bar for non-peaceful protest is extremely high, one I have never thought to advocate for in the U.S. in my lifetime. I believe we have crept up on that bar, as state sanctioned domestic terrorism has been unleashed in an indirect declaration of civil war by the administration.

I don’t know why anyone is worried about not giving weight to lives in pollution policy, when we’re going to win over protein.

A woman recording an ICE agent tells him "Shame on you." The agent responds, "Have you all not learned from the past couple of days?" "Learned what?" she asks Then he knocks her phone out of her hand

Renee Macklin Good's wife, Becca Good, released a statement and it moved me to sobbing tears: archive.is/ur35j

So a CBS Evening News reporter actually did a pretty solid breakdown of the ICE murder video, talking to a former agent who details all the ways Ross messed up. And yet: It didn’t air on the actual show tonight. CBS did post it to YouTube—and it has nearly 800k views already youtu.be/6ywLEESFDu0?...

Just another one of those hard to focus days....

Breaking: MINNEAPOLIS (AP) - Minnesota investigators say they can't access evidence after fatal ICE shooting and FBI won't work jointly on probe.

It was a murder. A murderer decided he wanted to murder someone today and then did. There is no ambiguity or whataboutism; case law is clear that someone not a danger to others that is running away cannot be shot at. You do not have to be prosecutor or lawyer to recognize and understand this.

ICE is now executing people for driving away. Phase 2 is here.

Learning a bit about orbital simulations. I'm using the REBOUND package and get pretty close to the Laskar solution of Earth's eccentricity evolution for the next 1 million years (including the 8 solar system planets and Pluto), but without relativistic effects. 1/2

NCAR is a unique & valuable asset - far more than a climate model, or observations, or technology, or training ground, or gathering space. It covers weather, space weather, data, climate, paleo-climate, and everything in-between. It's building is an icon, but it's iconic status goes far beyond that.

I’d say sad but basically treason.

This is the only parody song about geophysical fluid dynamics you’ll ever need: urldefense.com/v3/__https:/...

It appears that the U.S. Environmental Protection Agency (EPA) has, within the past week, scrubbed a large amount of climate change content from its official website, as well as *removed human-caused warming* from the discussion on its "causes of climate change" page.

Indeed, I'd still like to meet a clever climate skeptic.

Order of magnitudes matter. For example this is what happens when you zap stuffing for 20:00 instead of 2:00. #happythanksgiving

When you have an interesting planet to look at in the exoplanet catalog but the catalog reversed the mass and radius information of the host star (relative to the original publication) and it’s no longer interesting…

Somewhere floating in space is Russell’s syringe, waiting one day millennia from now to jab Starman in Elon’s orbiting car.

Not even a year in and we’re on the “kill my political opponents” stage.

How to start papers:

High ocean heat lies below the ocean?

Wait so the Dems are going to get a “future vote?” timesofindia.indiatimes.com/world/us/us-...

Have you heard about this? "As the govt shutdown drags on, buildings at NASA's Goddard Space Flight Center (HQ for the Webb telescope among other missions) are being emptied without notice. Highly specialized equipment is at risk of being thrown away like trash." h/t @climatebrad.hillheat.com

Authoriatrians usually don't care about the citizens apnews.com/article/snap...

Exactly! Which makes the real climate shift way scarier. Like shown by the data from svs.gsfc.nasa.gov/5452/

Early stages of the Kessler Syndrome

Indeed, and what's more, the entire "we want debate" charade is just that...none of these people will talk with anyone who knows what they're talking about.

Reminder that we still need scientists despite AI tools, mad almost-trillionaires, and other ideological wars.

The new UNEP report is out with the latest estimates of 2100 warming outcomes under current policies, NDCs, and net-zero targets. Here is how it compares to both the IPCC scenarios and other estimates (CAT and IEA, who will release their own updates soon!).

Maybe it is a lost battle after all, if after the first modeling in the 1960s, or Hansen's testimony in the 1980s, or six iterations of IPCC reports, "it's not the apocalypse" is seen as a coherent standard or a worthy point of attention. www.nytimes.com/2025/11/02/o...

My new essay on the future of life in space just appeared in Noema magazine! Kudos to Satwika Kresna for the lovely artwork.
