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've been reading about what some of what the rich and powerful openly state they believe, and it's pretty scary. They are extremely out of touch with reality. I wonder what they believe that they're not open about.

So far, I've read about:

Effective altruism

  • seems to be about exploiting people to amass as much wealth as they can, then use that wealth to "help" humanity by building space ships to launch rich people into space or something.

Effective accelerationism

  • explicitly doesn't care about humanity, only "technocapitalism." Is fine with AI destroying humanity, because that would be the natural evolution of intelligence.

Peter Theil

  • believes all kinds of crazy shit. Women and democracy are a danger to humanity because they're anti-"libertarian". World should be a collection of city-states or floating cities ruled by corporations.
