The Republican campaign to stop the U.S. EPA from protecting the climate Β» Yale Climate Connections An audacious effort to destroy climate regulations is likely headed for a showdown at the Supreme Court.

I read EPA’s 302-page proposal to nuke the endangered endangerment finding so that you don’t have to, and wrote about what the insanity all means for @climateconnections.bsky.social. Thanks to @gregdotson.bsky.social, @hausfath.bsky.social, @michaelemann.bsky.social for the input. Article & 🧡(1/14):

NEW FROM @reuters.com: Top U.S. law firms have sharply scaled back their efforts to challenge the federal government in court, especially on behalf of pro bono clients, in the face of threats from President Trump.

The Lab-Leak Hypothesis Made It Harder for Scientists to Seek the Truth Virus origin stories have always been prone to conspiracy theories. COVID disinformation has threatened researchβ€”and lives

More than 3yrs down the line this has held up surprisingly well, very much because of @lewan.bsky.social prescience borne from climategate and previous clashes with USRTK

This is one of those moments when the hollowness of our democratic systems becomes visible to the public. Facts are verified, but deliberation is pure performance, and accountability is nowhere. The system absorbs truth without ever acting on it.

I know there's a risk of amplifying the fascist horror show, but I think we need to be aware of just how far things are going, especially as this man is a Republican candidate for governor of California. All the old safeguards are being deliberately torn down, and the unspeakable normalised.

More people are turning to ChatGPT for health advice. Many would use it for self-diagnosis.

But here's the problem: These tools don’t just answer, they align. And that’s where things get risky.

The most disheartening thing about America’s descent into fascism has been the abject cowardice of virtually all the people and institutions that could have stood up and refused to comply.

A photo of me holding a placard stating: Palestine Action Are Protesters Not Terrorists

If the police arrest me for this, it's a direct attack on the expression of opinion: ie on free speech. But the Terrorism Act is so madly oppressive and loosely framed that I have no idea which side of it I'm on. And I suspect it's the same for them.

Opinion | I Watched It Happen in Hungary. Now It’s Happening Here.

This perfectly describes America's elite institutions.

"They cling to the illusion that they can preserve their independence and integrity while making deals with a strongman, just as Hungary’s elite believed they, too, could emerge unscathed."
