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 do not think the world will like a century dominated by the CCP quite so well as it likes rapid decarbonization, but I guess we take what we can get .

I'm doubtful it'll be any worse than a century dominated by the US, they're all doing the same evil shit.

If countries are careful to buy solar modules instead of things like inverters and other grid interconnection hardware with more complex electronics, it'll limit Chinese power in a way that you can't limit the ability of an oil or gas supplier to cut you off.

Good advice. I was actually thinking simply about being the center of the global economy and how that typically makes a nation a superpower. Technological espionage is a whole other issue.
