Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

I used to have a subscription to the NYTimes, which I eventually outgrew a couple years ago.

I will say that there are few columnists in the paper that I agreed with as regularly as Paul Krugman. He's kind of a rare creature, I think. Most people wildly over-estimate their own empiricism, but Krugman seems like the outlier who really does look at math and then say, "Hmm... it looks like the data says this thing I taught to hate is effective at fulfilling my goals. I guess I support that now." And he's never been a radical, which I think gives him credibility.

So good for him. I'm glad he's out there, like Casandra, calmly explaining with a chalkboard to mainstream centrists why bringing a giant wooden horse gifted by your enemies into your guarded city is very unwise. I hope it breaks through from some people.

That was a good article. I meant “still” in the sense that it shouldn’t just be an opinion. They should have given him the front page. At some point, decorum and norms have to give way to the emergency we’re experiencing. He’s respected, so maybe he can make a difference.
