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.

In multiple ways, we are seeing the end of the oil age.

Change is coming.

There are things that can be done to curb demand without cutting travel itself, like lowering speed limits for fossil cars.

But the right wing political machine runs on the opinion that stuff like that is all left-wing, and that right-wing means unlimited cheap gasoline.

"Reality has a well-known liberal bias" and all that

Higher gas prices should promote more conservative driving habits as well, but they don't. People don't drive the speed limits now, they won't slow down to save money, and they make automated enforcement a political liability, ensuring anyone who tries to rein them in gets the boot. Will sure be interesting if they completely run out, but just like the band continued to play while the Titanic went down, it's going to be business as usual here until reality slaps us in the face.

EV owners were derided for driving "slowly" (within the speed limit!) to save power and not have worries about charging, so we do know that car owners will actually do stuff like that once they're actually concerned. Fossil fuels still seem to be cheap enough that people don't, though.

I am not sure that rational choices by EV drivers can be generalized to the population as a whole. Consider the "roll coal" tinky winkies.
