Motion to permanently abandon the term "oral exam" and instead say "verbal exam" when it comes to PhD comps, proposals or theses... thanks.😅

Why Bill Gates’ climate memo is being celebrated by skeptics while frustrating scientists

Since everyone has thoughts™️ on the Gates memo… here’s my addition (basically addressing why skeptics are celebrating it and climate scientists are lukewarm about it when it is fully in support of continued efforts at decarbonization. theconversation.com/why-bill-gat...

"The disaster industrial complex, it turns out, is a network of supply chains that help people and governments reboot after catastrophes."

Maybe climate change could be good for growth after all 🫣

oh, look at that... surprising absolutely no-one, the percent of land area in the Contiguous US facing unusually hot daily high and low temperatures during the months of June, July, and August is trending up in recent decades.

Are annual precipitation and extreme precipitation increasing in the United States? Yes. That's what the data show.

Short 🧵starting with this chart👇, showing Annual Precipitation in the Contiguous US, 1901-2023. While there's wide annual variation, it's trending up.

Do these 2024 values for 'Yearly absorption' look right to you? Does this merely reflect the observed atmospheric CO2 increase in 2024? I'm struggling to interpret the spike - yes, emissions were higher last year, but not by this much.
October 21, 2025 at 4:41 PM
Uh, yeah… they’ve hit a record high every single year for at least the last 67 years…
