So the plan is to put political officials in charge of deciding which science is ok to do. This naturally means no more study of climate, since Republicans will never approve any funding for that.

Today's letter to my congressmembers:
Launching a major and unnecessary war without the approval of congress or even seriously trying to explain it to the American people is a clear constitutional violation. You need to impeach Trump. Now. Whether or not it gets Republican support, or succeeds.
Doing this articulates a clear vision for keeping the powers of Congress and ongoing constitutional rule. Without it, you're acceding to dictatorship.

It looks like the shift in refrigerants to ones which don't cause as much warming is happening irrespective of US politics.

Start talking to local politicians about how much you want them stopped. They tend to have a lot of tools to do so.

The scale of concentration camps that Trump and buddies are planning to build is really quite enormous.

This is why there's so much opposition to nuclear power — the risk of regulatory capture over the multi-decade useful lifetime of the plants makes the risk unacceptable.

You can't maintain a complex technical infrastructure indefinitely when keeping it operating depends on retirees who used to work with it professionally volunteering their time. This operational model may well bridge a gap of a few months, but it needs paid staff.

TL;DR; we have something of a choice between long-term instability which kills off the wealthy and powerful, resulting in broader distribution of wealth and power, or an event rather more like the New Deal where wealth and power are nonviolently more broadly distributed

Via the NYT, another chart on how the Republican plan to repeal the Inflation Reduction Act would result in higher greenhouse gas emissions by the US. Not mentioned is that this makes other countries less likely to cut their emissions as well.
I've edited the text above the chart to correct a typo.

Making plastic is the oil industry's exit strategy. Burning it creates incredible air pollution, and recycling it is sufficiently low-value that people burn it just to be rid of the stuff.
It's well past time to limit plastic manufacturing.

Biden has really sharply cut oil and gas leasing.
This is important because once a lease is issued, it's treated as a property right to drill and extract, which makes it much harder to fight.
It's by far the most effective leave-it-in-the-ground measure the President has.
