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.

The Cold War sowed the seeds of this self-immolation long ago. By casting the conflict between the superpowers as an ideological showdown, both the United States and CCCP began to define themselves in terms of opposition to a strawman idea of what they thought the enemy was. E.g. America was a country with a strong unionist movement, but quickly turned on itself with Communist witch-hunts and distrust of centralised planning (it didn’t help that the security apparatus of each power were genuinely infiltrating grassroots movements in the other.)

Obviously the Soviet Union was first to fall, but the poison was already in the blood by then.
