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.

Not turning the public against climate action, for one. We still need political majorities if you want to get anything done.

Second, we had the solution in the 90s with nuclear power. Now it's inevitable that we will see 2,5-3 degrees warming, since renewables can't replace reliable sources of energy and the world isn't willing to de-industrialize. By not excluding nuclear power, net zero by 2050 is achievable. By excluding it, net zero will never be achieved.

We might de-industrialize our country, but industry will just move to countries that do have reliable energy infrastructure. Look at industry moving from Germany to the USA, for example.
