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.

Wildfire particles and water being injected into stratosphere by “overshooting” storms: in increasing amounts, and higher up, as climate change generates more fires and more powerful storms.

Scientists flew a plane through powerful summer storms. They found a lower stratosphere that looked “more like a smoke cloud” than the typically pristine area they expected. 🧪🔥☁️

What hardly anyone knows: they can poison the water that remains.

🧪 If this observation holds up, I think it’s the first direct signal we’ve detected of a dark matter particle (rather than indirectly inferring their existence from gravitational effects. Exciting!
I wonder if it’s consistent with what we (haven’t) seen at the LHC…

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

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

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.
