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.

To be fair, this started with millennials. We've known we're fucked for many years now. But we didn't grow up with it the same way that these kids did. We thought we had a future for a little while.

I'm from 1980. I'm glad I don't have children. I hope I can avoid the water wars, but I'm not sure I'll choose to stay around long enough to see Hayley's Comet again. I don't think the collapse of global society (including, but not limited to the Internet) is eminent, but it does seem damn-near unavoidable: We need to act globally soon, and convincing/replacing current global leadership seems like it will take too long.

I'll take [action for slim chance of success] over [inaction for guaranteed failure] every time.

This is exactly an argument Kohei Saito makes in his book Degrowth - even if we know the odds are slim, do we not have a moral imperative to try while we still can?

Haha come on, I’m a millennial on the wrong side of 35, and climate climate change is just one of the things fueling my mental health crisis. SMH filthy casuals.
