I like rocks.

I think and talk about plate tectonics, geological hazards like earthquakes, the history of the Earth system, and how we silly humans can live sustainably on our amazing planet.

Coming together to eat the food we share has been part of humanity from the very beginning. I wrote this post after a Thanksgiving week lecture on evidence for Neanderthals and other ancient people making prepared mixtures of grains, lentils, and other foods.

November 25, 1988 - a reminder of damaging #earthquakes in eastern Canada. A M5.9 earthquake rocked #Québec. Felt strongly within ~500 km (Quebec City, Montreal, #Ottawa) and felt to more than 1000 km (Toronto, Detroit, Boston, NYC, and Halifax):

"Ask detailed research questions to find relevant papers"

None of these are detailed. None of these are actual research questions.

We are no longer the target audience of Google Scholar.

🧪⚒️ One fascinating implication of this study is that this “seafloor weathering” mechanism is more prevalent at slow spreading ridges where there is more talus-generating faulting: so an increase in global spreading rate would increase degassing at ridges *and* decrease sequestration in the crust.

Fascinating and timely work on the intrusion that preceded the #HayliGubbi eruption - this will turn out to be a very valuable example for volcanologists!
The #HayliGubbi eruption came after a period of unrest that started in June-July 2025 with a large dike intrusion in the southern sector of the Erta Ale rift. Our InSAR study will be out soon but you can have a summary at the link below. @earth-science.bsky.social #geoscience

This study about overcoming LLM safety guardrails with "adversarial poetry" now has me thinking about a post-apocalyptic scenario where the only way to access the knowledge of technologies of the old civilisation is through a game of poetic wits with the LLM security systems.

I feel this may be missing a few things, although the “basically granite” comment is spot on. 😂

Please! A bit of precision here would do a lot of good.

Sure, using AI instead of machine learning may make the media pay more attention to your study.

But do you really want the people reading the stories to believe that your results came from asking ChatGPT? And yes, they will believe that.
Journalist challenge: Use “Machine Learning” when you mean machine learning and “LLM” when you mean LLM. Ditch “AI” as a catch-all term, it’s not useful for readers and it helps companies trying to confuse the public by obscuring the roles played by different technologies. 🧪

A more expansive (and likely just as correct) form of the argument for why geoengineering our way out of the climate crisis will not work.
Humans will NEVER colonize another planet. Never.

If we can’t even agree to do the minimum to keep Earth habitable, there’s no way in hell we’ll cooperate to make another planet habitable.

⚒️ If there isn’t already a law stating something like ‘stories about volcanoes and earthquakes in British tabloids are always (i) ridiculously melodramatic, and (ii) completely wrong.’ - we should make one.
Speaking of bad science in media (and I am using the term "media" pretty loosely here), allow me to use The Daily Mail as evidence of why you should get your science information from reputable agencies rather than crap websites. I'm not going to link the article, but it looks like this:

Thread. “AI is patching up the holes in conspiracy theories and so making them seem more reasonable, making them easier to spread and more resilient to collapse” was not on my bingo card.

AI relieves the pressure of cognitive dissonance. That’s … not great.
Bellingcat’s contact email has always been a magnet for people with fairly unusual views; paranoid delusions, sprawling conspiracies, the works. But recently, the pattern has shifted, we’re seeing more and more emails clearly written with ChatGPT.

🧪⚒️ Makes sense that alteration of a big pile of sulfides could still be an energy source , but the amount and diversity of life supported after active venting has ceased is a cool surprise!

Yet more evidence of how stupid and destructive deep sea mining would be.
Scientists long assumed that inactive vents, without the mineral-rich plumes that make active vents so mesmerizing, didn’t host unique lifeforms.

“It turns out that we just weren’t looking very closely,” says marine biologist Jason Sylvan.

*Climategate awkwardly raises its hand*
A COUPLE OF EMAILS IS NOT A WHOLE NEWS STORY SAYS A FORMER NYT REPORTER

I CANNOT RIGHT NOW MAN, I AM CRASHING THE FUCK OUT. LOOK AT HOW STUPID THESE ASSHOLES THINK YOU ARE! THEY THINK WE ARE ALL TROGLODYTES!
The emails that you’re seeing now are news in themselves, but that’s because of how they’re coming out—a congressional committee released them—& the context in which they’re being viewed. A guy emailing a reporter talking about old girlfriends or saying someone is “dirty” is not a whole news story.
