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.

Holy shit, that second bullet point. The hundreds of thousands of people donating small sums of money are somehow less representative of the electorate than the two hundred people donating over a million dollars each, because reasons (just not mathematically sound ones)

It's the 4th bullet point that gets me. "We should spend more time going to right-wing-dominated spaces (and also restaurants)". Because only right-wing communities are "real". Anything lefties do is elitist.

The second bullet point is itself a paradox. By definition hundreds of small donations would represent the electorate better than individual large donors.
