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.

Well on average, people are dumb, and the average goober probably doesn't know how to properly manage the use of a PHEV to get good mileage. It's a learning process, and the cars should come with instructions about it taped to the dashboard so that goobers will notice.

Basically you need a charger at home, and you use the EV mode for city driving, and the gas engine for highway trips. You can get more complicated to max your efficiency but the basics are simple enough for the average goober to learn. When I got one, the dealer knew a lot less about the vehicle than I did. They didn't tell me how to do anything.

Dealerships are a huge problem. When I picked up my Volt, it had no charge. They had the two chargers that GM required, they just didn’t use them.
