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.

I am not an American, so I have to ask: Is AOC really that radical? To me she looks like a left leaning liberal with the most radical idea being MMT. Other then that it is normal talking points of a left leaning politican.

any other country would view AOC and Bernie as centrist at best – but our Overton window has shifted so far right that centrist is seen as full-on revolutionary communist …

I honestly thought they were some European style social democrat types, but then I looked up their climate policies and turns out Macron has actually passed more radical climate laws then the two of them are even proposing. It is insane how Americans believe that two politicans would be revolutionary communist, when a former investment banker turned neoliberal politican is more radical then them.
