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.

Oh we are so absolutely fucked as a species. Return to monke

...yeah monkes and all other mammals are fucked right along with us.

Maybe a few tardigrades will survive, and after a few billion more years of evolution they'll grow up to be less of an asshole than humans did.

Ah fuck you're right. We're going to be the cause of the next mass extinction

We already are the cause of the current mass extinction.

Anthropocene Extinction Event

We are currently driving the next mass extinction event.

I've read up about it before, but news feeds are currently completely overwhelming all our brains. That is despite mass extinctions being one of the most important things we focus on

Just so we all remember, Mass Extinctions usually don't mean anything like all species on earth dying. Like, even the big ones killed max like 75% of genera. We won't end life on earth unless we do a very impressive nuclear war or hit a runaway heating threshold that turns Earth basically into Venus, neither of which is even remotely likely. Possibly more sadly, all signs appear to be pointing towards most stuff staying alive and just suffering.
