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 feel like the US shouldn't work with a fascist dictatorship that's actively committing genocide, especially in the current political climate.

Makes sense, hardly news, but helps to restate periodically. All three need to show they are serious by closing down coal power fast - China still has a lot. CO~2~ emissions per capita in China have been higher than european average for many years now, their response was always 'so what about US'.
25 years ago I made a presentation with some climate-equity model graphics at the Energy Research Institute in a village some 10km beyond Beijing, the director Zhou Dadi (a key policy guy) said - "well we have plenty of experts who could make such model calculations, the problem is trust, the reason I believe you is that you came on the bicycle" - as I had (and also by train from europe). I doubt he'd say anything like that now, in the concrete jungle they have built since.
