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 don't think that Democrats should turn away from their growing number of middle-class supporters in order to pivot to a platform that has no record of winning elections. The US economy is going to suffer over the next couple of years and the appeal of a "return to normalcy" party like the present-day Democrats will grow.

It's worth considering why the Democrats failed to persuade the majority of voters that electing Trump in 2024 would be (among other things) an economic disaster, but nonetheless it's going to be an economic disaster and voters won't be happy. I expect that Trumpism will have no political future if (and that's a big if) free elections are preserved.
