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 about independence from any monopoly. Energy companies own the field, equipment, transportation, electricity generation, and distribution. I'd like my own generator and storage to lower costs.

Nuclear perpetuates the same system where safety is cut as a cost saving measure. You know they would be less safe if they legally could. Also the infrastructure is in bad shape to move radioactive waste by rail- ask Ohio.

Also you are directly dependent on the country where you get your uranium from. Which for Europe was/is mostly Russia. That also does not seem a good idea.

Akchually, Czechoslovakia used to export uranium to the USSR because it had the greatest, most accessible reserves of the Eastern Bloc.

That may be correct, but recently it looked like this:

The Czech reserves (which are still more than US's) were probably just more readily available or easier to purify.

Anyway, I'd prefer this list because your chart is EU supply only.

Interesting, but you just have to keep in mind the definition of reserve, where profitability is part of the calculation. Also reserve does not tell much about extraction.
