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.

That is inaccurate. You can look up LCOE for all of these and Nuclear is right up there with Gas. Also, you can't have 10% of your generation be nuclear with solar and wind making up the majority. You literally cannot produce that much electricity. Nuclear, being arguably the most efficient source of energy and the largest capacity, it makes sense for nuclear to be in place of our coal and gas plants with solar and wind supplements. But hey, that's just what I studied for a living.

I did. That was true 20 years ago. It's not now
