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.

This word was rejected by geologists. But it’s already taken over the world. A panel of scientists rejected the term “Anthropocene” — but others keep using it. (wapo.st)

This seems like an attempt to shift the blame to another group you don't identify with. We collectively did this. Humans have been clearing forests and altering ecosystems for millennia, and the only thing that really changed is industrialization and the ability to easily extract massive amounts of fossil fuels from the earth. Technology made that possible, and once the cat was out of the bag it became very difficult to put it back in. Sure capitalism sucks and all that, but humans, organized by country and loosely in competition with each other, were bound to fuck this all up regardless of whether the Soviet Union or the US or the British Empire or China was "in charge". It's a prisoners dilemma stacked on expectations of comfort. And sure a global authoritarian government exclusively focused on sustainability could pull this off, but people sure as shit wouldn't like it, so here we are. Capitalism and it's effects to undermine solutions in the name of profit are absolutely making it worse, but to place exclusive blame on capitalism seems naive and ignores human nature itself.
