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'm running a community at https://slrpnk.net/c/cdr but not sure how discoverable it is right now. Some of you might find it interesting (if anyone joins, and I actually start posting regular content).

Nothing wrong with the idea of removing...but actually getting to the point where we're not adding CO2 to the atmosphere means not burning fossil fuels in the first place is necessary for it to make the kind of difference we need it for. And the way that CDR is getting pushed (and funded) is in large part as a means of creating social permission to keep on burning. That's a problem.

I agree completely. But I am used to talking to skeptics and I tend toward arguments that are simple to drive home without needing to point to this as human caused because media.
