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.

Is Carbon Capture Cause for Hope? a new facility to suck carbon out of the air shows why it's more complicated than that. (newrepublic.com)

The real question is how to make it profitable. Turn the captured carbon into building materials somehow?

As it stands, who pays for it? Can’t rely on government subsidies, and can’t rely on business doing it unless they’re compelled.

I wish it would work but I just don’t see how it fits in the current system at any meaningful scale.

So, trees ...

You might be onto something.

Limestone is also a suitable building material.

The problem is, usually the result of this capture process comes in the form of CO2 gas. Turning that into something useful takes even more energy.
