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's state subsidies in green technologies significantly higher than those in EU and OECD countries, distorting competition, researchers say (www.intereconomics.eu)

It'd be interesting to know how much of that is a mercantilist attempt to capture market share in other countries (i.e., dumping) and how much is reflective of a sincere effort by the Chinese government to address the climate crisis.

I suspect it's the former, since alongside China's renewables investment, China's emissions of greenhouse gases continue to grow, as does its consumption of coal.
