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.

Was actually not aware that emissions have gone down. Much more used to the US not doing anything or actively screwing people over (such as the arrest of Donziger) but at least it's going down.

Those increases by China are used by opponents of climate action to argue that it’s not worth doing anything,
Hate that too.

China has been doing thins to curb emissions and generally fix the environment like the Gobi tree wall. Course there's plenty more that could be doing but I digress.

It is; things could be worse than they are. The problem is that both absolute and per-capita emissions are going up, to the point where China crossed over to be the largest emitter on a national-total basis, and we're at the point where they need to be going down.
