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.

Republicans made a religion out of fossil fuels vs clean energy, because the Russian oiligarchs that own them told them to. This is what clean energy advocates need to defeat. Hopefully the manufactured oil crisis from Operation Epstein Fury has diminished the faith in that dumbass oil-worship system somewhat.

The one good thing is that it's economically getting harder and harder to ignore renewables and stay all-in on fossil fuels. If connecting solar+battery to the grid costs half as much as coal or gas, nobody is going to install coal or gas capacity because even if the government gave them a 100% subsidy for construction, they'd need to fuel it forever. No fuel = no electricity. Meanwhile, the sun is free, forever.
