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'll note that 2.5°C of warming by 2100 is a significant improvement over the trajectory we were on a decade ago, even if still far from where we need to be

So, so many people are going to die. The current upper class is making all the mass murderers of the past look like specks, and yet, I don't see any more protests than I ever did. It's... truly surreal.

Oh now, let's not imagine the majority would say no thanks to profligate consumption if they had the means.

The problem is the system (or lack thereof) that allows it to happen, not so much which individuals win the absurd game.

And the threshold of consumption where you're pay of the problem is a lot lower than most people want to face.
