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.

Pretty easy on modern front wheel drive only engines. The skeptical part is brakes, HVAC, alternator etc rely on combustion engine. So it's possible to fit Prius type hvac, not sure what you would do about rear braking, transmission interlock, security system, radiator core, a/c core....

You could keep factory brakes and some cars already have electric brake pumps, etc. Maybe fit electric vacuum boost.

Diesel engines don't generate vacuum so there are a.number of options off the shelf.

Yeah, I forgot about all the systems that still use vacuum for power, too.
