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.

To be clear: there's a night-and-day difference between Biden and Trump, with the former having actually taking significant action, and being likely to take more if reelected. Trump will look to maximize both extraction and consumption of fossil fuels in a way that Biden simply didn't and won't.

A 10% decline in global oil consumption would be awesome. However to be realistic Russia consumes a lot of oil itself and sanctions do not cut out all oil exports. They certainly did not for Iran and Venezuela. Funnily enough 10% of oil consumption are US cars. So a ban of combustion engine car sales in the US would have solved that as well. With the EU and other allies joining, that would even be fast enough to actually beat new oil drilling in the US.
