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'm gonna make a second comment here because I think it helps to keep separate discussions in separate threads.

It’s classic prisoner’s dilemma and I argue in favor of doing what is right, not what others should do first.

This is not the situation we are in, and it's not what you are doing. You are arguing what everyone else should do first before the powerful can be demanded to change too. You aren't even arguing for both changing at the same time, you are saying "before you aren't holy you can't demand betterment from anyone else". Which is just illogical to me. A chainsmoker can tell me that smoking is bad and I should stop and they would be right. No need for them to stop smoking first.
