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.

It's rather alarming that this is being done without public modeling to make sure that they're not creating losers from the change in rainfall distribution patterns and such.

Is a radical idea that has insufficient study to give us confidence that it will work as intended. Research is necessary.

Certainly the major effort behind this as a solution is the fossil fuels industry as it smacks of a tech solution that deflects from the fact that we aren’t focused on rapidly reducing greenhouse emissions. There is a lot of these and the underlying problem is that CO2 pollution is continuing unabated. Greenwashing until emissions reduce.
