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.

While a Trump presidency couldn’t slam the brakes on the E.V. transition, it could throw enough sand in the gears to slow it down. And that might have significant consequences for the fight to stop global warming.

That’s not even thinking about the mining required to make batteries, or the copper needed for the motors.

Yeah, but... that stuff isn't going away. In a couple decades when an EV's worn out, all the materials will still be there ready for recycling. It's not like coal and oil where we dig them up and then set them on fire and they're gone.

Don't worry, that coal and oil is still there too. Just hanging around in the air.
