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.

I've seen some cool stuff about heat batteries. Very interesting implementations of old technology.

Yea I wasnt sure if this was something new or not, but I'd agree that carbon capture isnt nearly as interesting as some of the new battery storage or renewable energy tech thats being developed.

The ReAct stuff isn't new. For a more industrial example of this, check out CarbonCure. It's not yet economical, though once you include external factors like carbon credits or other tools that financially punish emissions / reward sequestration it theoretically can be. As the the tech scales up, there's every reason to think the cost of this kind of carbon-enriched concrete will at least be priced in the same league as traditional PCC.
