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.

Sure, that's what has been happening due to the high regulatory hurdle for getting a plant cleared. Compared to other countries, it takes a lot longer in the US to get through the regulatory hurdles.

I think that, because of events like Three Mile Island and the influence of fossil fuel competitors, politicians have been using overregulation as a way of limiting the deployment of nuclear power generation and not simply as a means of making it more safe.

Having an administration that is pro-nuclear would probably help the skill decay issue, if we're starting new plants more often then there will be less time for the knowledge to die out so future plants can be built faster, cheaper and safer.

Of course, this is the Trump administration so how much of this is performative and how much is substantial change has yet to be seen.
