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.

this is disgusting. cutting down old growth trees to burn in a power plant is treated as emission free and therefore entitles this company to billions in subsidies. and they're British! fuck right off there bud I'm using those trees to fuckin breathe

Burning wood to make electricity is one of the stupidest things I’ve ever heard of.

It's not that dumb because it can be a somewhat "closed system" for carbon capture. You grow trees that capture carbon, you burn them, releasing their carbon and you replace them with new trees and so on. Obviously it creates other problems like monoculture and such but as a non fossil "low carbon" energy source it could be locally interesting if you have space and water to spare.

They are burning ancient woodland. Areas of trees that have never been cut down. We're losing them and need to stop.

Well yeah that situation is definitely bad obviously. I just argued on the point of burning wood for electricity.

I’m not aware of any water to spare anywhere.
