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.

When you do pure central planning it really has seen underproduction historically. However China has a mix between central planning and a capitalist system, which is more like the Western economies during WW2, then the Soviet Union. Those have generally seen some massive production increases.

Also Evergrande is a sympton and not the problem itself. The issue is that China has built significantly more housing then it really needs. That uses a lot of steel and to produce steel you use coal(there is also a process using hydrogen, ususally made from fossil gas).

As for Russia, China lacks the pipelines to buy Russian gas. Currently they only get it from the gas fields in Russias far east. However Europe was supplied from gas fields further west. There are no pipelines between those systems and Russia has been exporting at nearly capacity for some time.
