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.

The world's corporations produce so much climate change pollution, it could eat up about 44% of their profits if they had to pay damages for it (phys.org)

Huh that's very reasonable actually. Generous even. Now let's see what they can pay workers.

As little as they can get away with.

Yeah, I was thinking… only of their profits? So they can afford to still make a shitload of money and not put out all that pollution?

[–] Denvil@lemmy.one 4 points 1 year ago (1 children)

I mean this is paying for damages, not fixing the pollution

I’d like to see a calculation for that. It seems expenses to be more careful would be comparable, but who knows.
