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.

Are voters clustered in the center of the political spectrum like a bell curve or are voters clustered in two camps at the extremes? If it's the latter, I could see the "don't vote" strategy working. Otherwise, it's bound to backfire because the leftmost candidate would need to move so far left to gain your vote that they would cede more voters to the candidate to their immediate right than they gained by moving left and lose the election as a result. They therefore don't consider you in their choice of policies and move farther right as a result, which seems counterintuitive, but it's true. This of course assumes a single political axis which isn't necessarily accurate.

This is literally the opposite of what has been happening. The Dems keep moving right, and giving up voters on the Left. Every election they scream about the Leftists voter base that is both:

  • A) To small to cater to
  • B) So large, as to be able to swing elections

And their strategy isn't because they can't get Leftist voters, it's because they'd rather let the Republicans win, then enact Leftist policy.
