Climate - truthful information about climate, related activism and politics.

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.

You're right in that the whole drill-baby-drill thing is utter self-destruction which may still work passably over the course of the next four years but not beyond. The IRA right now is solid industrial policy and I wish us Europeans were competing. (Wild guess though, the repeal of the IRA will go much like the repeal of the ACA last time around.)

However, my point is that China is in a phase where it's doing more with more, and its motivation is such that that will stay that way. The only reason Chinese emissions are stagnating right now is that their economy is faltering. At this point, the Jevons paradox is simply eating their renewable power/electric car/... gains. Granted, that is preferable to them continuing to buy ever more fossil-fueled cars.

The motivation for producing this technology will, to a degree, determine the outcome: Solar panels off Temu, delivered to your doorstep using a fossil-fueled plane are a thing that exists.

What happens when the importing blocs (US and EU) rethink their climate policy (because right-wing morons think that's a good idea)? Chinese products will adapt quickly.
