Giving a bully your lunch money doesn't make them leave you alone. It shows them you're an easy mark and encourages them to demand more.

We have more than enough evidence to conclude that the Trump administration

-is committed to attacking academia
-cannot be trusted to honor its commitments, nor to follow court orders
-has weaponized "fighting antisemitism" in bad faith
-will use Cornell's appeasement to go after other universities

We’ll see if and how govt funding is “restored”, and what does that mean in a country with low overhead rates and slashed funding for science overall.

The “funny” thing in the books is that the ways men after 200+y of full control talk about women seems grotesque and caricatural, and yet it’s exactly how men talk about women in many context (now especially on X, out in the open). The first reaction is to scoff, but if you wait and think a second…

When I was a student, as the student representative I’ve been in a few faculty meetings that ended in fistfights - all man, and all physicists. They loved bickering with each other, but it was pretty pathetic to watch from the outside…

Ultimately, we’re just 2 researchers. We can’t make investors in these startups do anything differently. Our req is that they think carefully, and beyond the logic of short-term profit. If they believe SG is worth exploring, could it be that their support will make it harder, not easier, to do that?

"The goals of doing research into SRM can be diverse: identifying risks as well as finding better methods. But research won’t be useful unless it’s trusted, and trust depends on transparency. That means researchers must be eager to examine pros and cons...

Over four intensive days, more than 200 participants (and 52 speakers) from around the globe came together to show and discuss the science, impacts and ethics of SAI, as well as next steps for assessment and research. All 4 sessions have been recorded and are available on the WCRP YouTube channel!

There is no climate model, even under 4xCO2, where temperatures rise +20C. Not even 10C. While the explanation above for Earth/Venus differences is fully correct, there are other physical reasons indep of models and fully consistent with paleo records agupubs.onlinelibrary.wiley.com/doi/full/10....

I always thought that defining WG1 goal as “why you’d want to do emissions reduction” was reductive. Anyway, a broader disagreement we are not going to fix tonight over BlueSky-I keep hoping to find an occasion to talk to you in person! But thank you for the respectful engagement, I appreciate it.
