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.

I don't know anything about the situation in the US, but you get a great second hand EV for around 12.000€ here in Germany. Combustion is cheaper to buy but gets more expensive over time. It has over 250 moving parts, EVs have like 7.

problem with second hand ev is that if the battery has to be replaced, might as well just buy new car entirely

Nearly all cars I tried had SOH over 90%. The car I bought is from 2021 and has 94,9% battery health. Buy a 25€ OBD2-dongle and read it when you test-drive it. If the owner cared just a little, battery health is not a problem. Don't let fossil disinformation scare you.
