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.

California hopes that its stringent rules combined with financial support — truck purchase grants from state agencies can total as much as $288,000 per vehicle, operators say — will help spur truckers, automakers, warehouse landlords, utilities and charging companies to make the investments needed to create a carbon-free port truck sector by 2035, when all diesel trucks will be banned from the ports.

How does that help with railroad timetable disarray and general disinterest in expanding the overhead electrification of freight rail?

Expanding the number of ‘inland ports’ from which you move containers from train to truck on the other hand would cut down massively on the needed range and subsequent cost of your ports trucks.

That's a separate regulatory situation from on-road vehicles where CARB has power to act
