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 makes up half the global electricity generation from coal, so that is the country to watch. So if they continue the construction of renewables and the economy slows down, that could actually happen.

As for India they have changed policy to stop new proposals for coal power plants in the next five years. So only the ones in the pipeline will be built. That should massivly slow down coal growth outside China.

Also important to say it, but Japan is still a massive coal consumer, with no real plan to phase it out.

Its definately the country to watch. They had a huge investment into renewables last year, and the main idea is to flip most of its generation to it in the pending few years. If sucessful, the chart is going to see a very sharp decline.
