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'll note that their definition of harms includes a lot of things besides just greenhouse gas emissions and climate impact. Full paper here

Basically makes the case that as a society, we're better off with smaller cars.

Yeah, tax incentives only work for those making enough money to have taxes to pay that they can get a break on. The rest of us have no way to afford an EV, so they’re relegated to luxury vehicles for virtue signaling upper middle class people. Then they double down and block the cheap EVs from being here, so now that there’s finally hope of having affordable EV transition for the masses, it’s purposefully kept out of reach for us in order to protect the margins of domestic greedy OEMs.
