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.

Creating nuclear power plants should be a high priority. At 112 degrees, AC is not optional. The state should be making sure that everyone has access to low cost, clean energy.

Nuclear is mostly not getting built because it's expensive. That's why you see so much wind and solar built instead

Exactly. Nuclear is expensive and take decades to come on line. Solar is cheaper and more flexible.

Not to say some nuclear might not be unavoidable.

Nuclear is not being built due to opposition to it from so called environmentalists. It’s been a thing for a while

Yes, we definitely need vital resources like this to be state owned.
