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.

Also bonus points if everyone else is behaving the same way, and extra bonus points if thinking and acting on climate change is hard and depressing.

Basically the nature of the problem is precisely the sort of thing humanity is collectively very bad at (think of the pandemic, which IMO didn't need to happen and we're lucky biomedical science was there to save us with vaccines). We're especially bad at it in this neoliberal culture too.

Basically we're embarrassing ourselves in front of future generations like all of the atrocious dumb shit that's happened in the past.
