Well this has been a weird time to come back online after a quiet couple months. Pretty alarmed at how much of the climate discourse is about how to effectively compromise with Republicans. Climate work is ultimately about protecting people — and who eats these compromises?

See that’s why Twitter got unusable for me a year-plus ago (plus of course increase in hate speech). My replies just always filled up with people’s pet talking points whether based in reality or not. It no longer felt possible to have a fact-based exchange.

I’m not sure what you’re missing.

I use Bluesky exactly the same way I used to use Twitter with exactly the same type of experience (w less trolls for now).

Maybe it takes time to build connections back up? I’ve been here since mid-2023. It was quiet at first.

Harvard has set an example for other higher-ed institutions - rejecting an unlawful and ham-handed attempt to stifle academic freedom, while taking steps to make sure students can benefit from an environment of intellectual inquiry, rigorous debate and mutual respect. Let’s hope others follow suit.
