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.

it'd be nice to have some idea of where might be a good place to move to, if this is as inevitable as it sounds.

Not as nice as you think. You could dodge harsher winters, an energy crunch and crop failures, just to move to somewhere with heatstress, drought and cropfailures.

We must not view climate as the thing to watch. It's one part of a larger complex system of systems. Changes in the AMOC can trigger changes elsewhere, and more importantly, elsewhere is changing on its own too. Not just because of emissions.

It's a lot to digest, especially if you don't have a background in ecology, biology, environmental sciences or systems theory. But a solid easy framework is planetary boundaries.

It's all 9 boundaries together (plus any new ones discovered) that's going to pickle us. We are exceeding 7 of the 9 identified so far and there are and will be severe consequences for having exceeded our planet's limits.

I worry about climate change A LOT. I worry about Ecological Overshoot and Collapse due to Planetary Boundaries even more.

the all new EPA will abide, no doubt

True. True. But to be fair, the old one wasn't fit for purpose either. Lovely science, but still couldn't do anything about it.
