Climate - truthful information about climate, related activism and politics.

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)

Realized carbon storage efficiency is abysmal: typically -25% of estimates, and highly variable, and that's before you factor in the economics. You don't get anything tangible from CCS, either.

Trees are pretty good at carbon capture :)

While this is true, we only tend to plant monocultures.

[–] Jaytreeman@kbin.social 3 points 6 months ago

Very true. A forest is definitely preferable

Trees are sadly inefficient for the scales we need. I'm not saying we should cut down more trees or stop planting them, but it will take much more than that to get us out of the hole we've dug ourselves into.

I don't think there's a reasonable way out of this hole, but I'd rather be in a world with more forest, so I'll keep suggesting that.
