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.

At this point, I assume that we need to either grab pitchforks or just accept that we’re doomed. It is historically and materially unjustifiable to think that voting once every 4 years for people who, no matter what they say about environmentalism, will continue to support capitalism and the military industrial complex at the cost of the of the planet will somehow save us. The system is set up to perpetuate itself. It will not allow for it to be peacefully dismantled.

That said I’m pretty pessimistic about that actually succeeding, what with all the military power, surveillance tech, etc. So unless shit starts changing fast, I’m just gonna go with we’re doomed.
