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.

It's worth noting that he also fired many of the staff who know how to ensure that they're actually safe, as well as the staff who would approve financing.

Beginning investments nuclear at this point when renewables so obviously to everyone in the know are beating them on all accounts is extremely on brand for someone as dumb as Trump

Nope, today nuclear actually makes sense. Renewables are cool and relatively cheap but only as long as they output power. Then what? Spin up that coal power plant such as during night? And produce a ton of climate warming co2 and a lot of pollution. The problem is that we don't have energy storage nor a viable solution for it. Said that, cutting corners is a big no-no.

but only as long as they output power.

We could say the same about nuclear power:

EDF cuts nuclear production in reaction to soaring temperatures

Sure, they are not perfect. But newer ones are much more resilient to droughts. And such droughts are not that common, also while they affected power output it's not by that much - if I recall it was something in line with 10%.
