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.

Because they are not feasible. I don't know how many battery stories I have heard over the years and none of them have ever been mass produced. Discovering something in a lab is not the same as mass producing stuff.

Maybe you should look into the operating principles before you declare them 'infeasible'. They're a vessel filled with antimony, magnesium and a liquid salt electrolyte that self-separates according to specific gravity. Since both the anode and cathode are made of liquid metal, there's no structural degradation over time. They can be trivially scaled to just about any size you like and are made exclusively from Earth-abundant cheap elements. Just about the only tricky thing is that the operating temperature of a working cell is 600C, but that's hardly an issue for a grid-level storage facility.
