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.

Beautiful news. When blocks inevitably appear, (US belligerence, COP being coopted by fossil fuel companies) be like water - flow around.

Indeed this is encouraging. And if the US keeps this up I'd expect we'd eventually be sanctioned.

As Lisa Friedman reported: “China, India and Russia are not attending. Nor are Saudi Arabia or other Gulf nations whose economies depend on oil and gas.”

Pretty based move. The most impacted by climate change are all small nations; banding together against the superpower states is going to be critical for survival.

Sounds about right
