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.

That is certainly a worthwhile concern.

Edit to be clear: I think it is a worthwhile concern, not a reason to condemn all ecoterrorist action. It is just important that such action be well planned.

I think it pales in risk comparison to stuff like regular war though, and that keeps happening. They blow shit up for maximum impact and effect. whereas I would hope ecoterrorists are at least motivated to attack stuff in a non-environmentally-destructive way. Or at least, pick targets that have greater positive global impact than local negative impacts, but that kinda thing can't be an easy decision.
