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.

First post on the fediverse. Hopefully it auto loads the link photo but if not I'll put it as the first comment. Sorry for anything incorrect in handling this.

Exactly. The problem now is the extreme lag time to build new ones vs solar and wind. However having some truly base load facilities still makes me want more built.

Vast majority of power should be renewables and storage and I think for this community of Lemmy that is preaching to the choir.

If you strictly go off the number of deaths and shortened lives from cancer added up to years of a life even Chernobyl is in the 50-300 death range. To be fair I don't have a source for that at the moment and am going off memory. Hydro has had far worse single events in terms of deaths. There are even car racing incidents around the 80 deaths range. So I just never understand nuclear fear if run under a set of actually enforced regulations.
