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.

Yeah, I mostly agree on that. Nuclear may be more expensive and risky, but it's also very predictable. That kind of enables it to act as a sort of safety net to smooth over the variable nature of renewables, though changing the output of a nuclear power plant is a very slow process, AFAIK.

I'm not against nuclear power per se, I'm viewing it as more of a band-aid until more mature and universal grid buffers can fill the gap smoothing out the renewable input. Nuclear may very well be a necessary step for some nations to reach their climate targets, I'm not informed enough to judge that. But I fear that the money invested, lobbying and public opinion influenced by that seemingly easy alternative directly hinder the development and deployment of technologies that lead to a renewable, cheap and reliable grid.
