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 backup is nuclear.

I don’t really care what it costs. We’re trying to save the habitability of the planet. Damn the cost.

OK, then we just deploy a whole lot of storage capacity as fast as we can to support solar and wind. Nuclear only makes sense if it's cheaper than that, and it's not.

Cheaper long term, yes. Higher upfront cost.

Not quite sure which way you're pointing. Nuclear is ridiculously expensive up front. It has to run for a long time at 100% to make any kind of economic sense.

I’m not concerned about economic sense. I’m worried about keeping the planet habitable.

And we have another path for that. We really don't need nuclear at this point.
