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 fact that our current political climate completely ignores our impending extinction constantly kinda terrifies me. Our current debates are now just moral panics on queer folk which will not just worsen things for them (or rather us, since I'm trans), but will bring nothing to the table and, oh yeah, won't solve our actual issues. It's as if the people starting these distractions don't care about anyone but themselves...

To be fair, it's probably not extinction. There isn't enough fossil carbon to do that. It's more like a huge hit to the capacity of the planet to be civilization-supporting.
