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.

These school buses no longer belch pollution. They also give the grid a break. (www.motherjones.com)

Future this future that. The batteries are still expensive now.

expensive bidirectional chargers, software and hardware support in the vehicle

In comparison all those things are negligible in terms of cost. Its already completely standard equipment thats being mass produced.

tens or hundreds of kilowatts of feed-in power

No. This is not required. You can just feed into the grid through a standard wall plug or whatever is used in the US. This is a well proven method and works exactly like with solar power feed in. The current can be limited to whatever the hardware supports. However if you build charging stations, then these will already be capable of the power levels that you are talking about, so it wouldnt even be an issue.
