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 energy required, despite the quantity of lithium (which wouldn't be available anyway) would just surge carbon output to later reduce it decades later. We can't capitalism our way out by making more things. Stopping making everything would actually help more, but would implode the planet's societies. Throttling energy use by AI and other expensive processes would do more, now. Pushing the use of public infrastructure, even busses, would do more now. Getting people to stop using cars would do more now. Forcing employers to require jobs that don't need a physical presence to all be work from home would do more now.
