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.

  1. No, you shouldn't vote third party in America, or any country with a first-past-the-post system captured by a duopoly, because it flies in the face of the reality of game theory. Tactical voting is real, no matter how upset the idea makes people. Yes, this even includes deep-red and deep-blue states, or whatever your country's equivalent is.
  2. Yes, choosing to eat meat when you have alternatives means you place your convenience and consumption above the death of sentient and pain-feeling creatures. I think it's bad to cause harm when you have the option to not, even if it benefits you in some way.
  3. Yes, we should literally ban all fossil fuels, and restructure all cities such that the public transportation is more than enough for everyone. That this is even a matter of question is ludicrous.
