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.

Scientist Erica Chenoweth, who studies civil resistance at Harvard Kennedy School in Cambridge in the U.S., showed that every movement that mobilized at least 3.5% of a population was successful. This led to what’s known as the 3.5% rule — that protests require this level of participation to ensure change.

But the figure can be misleading, Chenoweth cautions. A much larger number of people are probably supporting a successful revolution even if they aren’t visibly protesting.

Using rainfall as a(n inverse) proxy for protests is very clever. Interesting to see how the MLK violent protests actually were counterproductive and increased the republican vote share.
