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.

When and how we might slip over the brink into catastrophe is impossible to foresee. But as the events of this summer suggest, we are already all too close to the edge of the kind of systemic failure experienced so many centuries ago by the Mayans, the ancient Puebloans, and the Viking Greenlanders. The only difference is that we may have no place else to go. Call it, if you want, Collapse 2.0.

The core message is valid but it misses the point of the problem which is that the people who will suffer the most from climate change are people living in poorer countries, not the rich world. The impact, although dramatic and highly undesirable, is manageable in rich world countries.

I agree. But for now, I would add. If everything continues as it is, even the richest economies eventually will fail. He mentions migration a key point to the foreseeable problems to those rich countries.
