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.

Better than nothing.

If we have to overbuild green energy to get a reliable supply, use the excess on things like this.

It's also has a directly measurable output (...input?) - I would prefer that money was spent on this rather than carbon offsetting, which is basically a scam.

Considering all of the car still on the road gas furnaces and stoves still in houses that need to be replaced all of the other pesky smaller sources of carbon emissions going to zero is going to be a pain in the ass, the last 10 or 20% being the most annoying of all so you're going to need something. Meanwhile we're already throwing away solar and wind power in excess of what we can do anything with, and we could easily end up with cheap enough solar that for about 8 hours a day there's literally unlimited free energy you could dump into something like this
