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.

China is also a bigger emitter per capita than most european countries - for a decade now.
Why do so many people only compare to US - a small fraction of the world - maybe as fits simplistic narratives ?

Not by per capital emissions rate. That's the rub. They consume horrendous volumes of energy and emit plumes of waste so they can... what? All do donuts with their F-1250s in the parking lots of bankrupt Walmarts?

Now they're at the heart of AI development, another phenomenal energy suck that exists to vomit ads to their perpetually ravenous residents so they'll buy even more shit.

Europe had problems it isn't the problem like the globetrotting industrial behemoth that is the US.
