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.

Nuclear is not happening in Europe and it never will, no matter how often conservative parties keep bringing it up. We have only two new build plants in Europe, Flamanville and Hinkley Point C. They are WAY more expensive than expected, no end in sight, way past the deadline. You can build like 80 gas power plants for the price of one of these monsters. And we're not even talking about permanent storage of the eternal waste.
The only country working with new nuclear energy recently is China because they need to get off of coal fast. So they are subsidizing hard. And that's only fraction of what they spend on new renewable, clean energy.
