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.

Basically, if we stop adding greenhouse gases to the atmosphere, temperatures stabilize.

The US actually passed climate legislation last year, and it looks like the renewables build-out is going to proceed quickly enough to start displacing fossil fuels over the next few years

Positive reports tend to look like modest incremental improvements, but we've been getting a lot of those.

Thanks, I really do appreciate it. I will say that the if in that first link is doing an Atlas' level of work, though, and it's the point where my optimism has dropped the lowest
