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.

imho we should tax any vehicle that puts an inordinate strain on the roads. ultra-heavy EV's like cybertrucks and hummers are ridiculous and inefficient, and the purchases knew it when they bought them.

but also the cummins diesel powered pavement princess my colleague drives BY THEMSELVES TO THEIR OFFICE JOB day after day, I think that should have to pay an excise tax.

work vehicles certainly deserve cutouts, but they need to be work appropriate vehicles, not just jacked up asshole haulers.

work vehicles certainly deserve cutouts

That thinking is what got us SUVs. Work vehicles earn income, and so probably don't need cutouts.
