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.

Environmental Protection Agency moved to repeal the Obama-era “endangerment finding,” a declaration that because carbon emissions and other greenhouse gases (like methane) endanger public health and welfare, the government is justified in using the Clean Air Act to regulate them.

GHGs are not "pollutants". GHG warming does create earlier springs (melt season) and drier forests from which fires can spread wider, and pollutants drifting where people live. The clean air act was still the wrong framework to try to extend to GHGs because it applies to pollutants, and assholes would reverse it.
