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 means centrists can conveniently forget about the promises they made to shrill, naive environmental activists which was getting hard to do anyways because it meant they had to pretend they didn't hate environmental activism and that their lukewarm embrace of it was because... reasons...

Now those people can shrug and with a big smile gesture at AI and say "I am really sorry but we have to" and everyone just nods their head in resignation as if we weren't killing the entire biosphere off for a vacuous series of scams nested inside of one another.

AI is invaluable to the ruling class just for accomplishing that alone.
