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.

It looks like America is self-destructing. I'm not sure that's a bad thing for the planet in the long run. But sure, it'll cause a real mess going down.

And of course it is tragic. But somehow I'm less worried about the climate change aspect of all this - at least on a planetary scale - compared to how worried I normally am about climate change.

This is how empires die. Power and wealth accumulates at the top, until eventually a tipping point is reached, and those with power then use it to frantically loot the rest of the nation and skedaddle to foreign lands with their ill-gotten wealth as the empire balkanizes behind them.

In truth, the looting phase started with Reagan, but in recent times it's begun to accelerate, particularly when Trump is in office.
