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.

They can plan to do anything they like. They planned to win a war with Iran and instead turned a former international strait into one firmly controlled by an adversary.

They are very likely to lose the House. There is a decent chance the Senate flips as well. The administration will be able to do little.

Also, who wants inefficient cars with oil prices where they are?

Oil execs, aka Trump's friends. US people have been complaining about how hard it is to find a car they actually want for ages. Their dealership model seems to be geared for extracting money from them, and worse mileage at higher prices would be just more of the same.
