#Adaptation Controversial take:
"Build Back Better" or "Build Back Wiser" is not prudent in a nonstationary climate.
If a disaster strikes, it means there's already exposure.

Things that will get you kicked out of academia forever:

- reporting harassment

A guy makes ONE tiny mistake (has a years-long friendship with the world's worst sex trafficker; brags about sexually harassing colleagues; is racist; says women are stupid) and his whole LIFE is blown up (does slightly fewer speaking engagements; keeps teaching at #1 university)??!?!?!?!?!
So Harvard is keeping this guy, but Claudine Gay had to step down over ginned up plagiarism accusations and bad-faith accusations of anti-Semitism.
Got it.

My latest for @science.org: A remarkable set of high-resolution climate model runs, computed over 900 (!) days of supercomputing time, are revealing how warming-induced changes to Earth's wind patterns due can prime huge spikes in extreme rainfall.
But the MESACLIP runs also do much more than that.

We all become disabled or we die. Compassion for our other humans (or even if purely selfish, yourself), is the least we can do. Alice was an oracle and we need to honour her life's work.
Our beloved Alice Wong has joined the ancestors. It was one of the great honors of my life to call Alice my friend, co-author & co-conspirator. She was a true genius, a force of nature the likes of which the world has never seen before. I love you, Alice, and am equal parts grateful and devastated

Brevetoxins are potent neurotoxins produced by certain algae and cause significant health problems (“red tide” is one form).
