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.

The Great Green Wall's one of the world's most ambitious eco-projects. Is it working? | tldr: no (www.npr.org)

Sltldr: "They're just throwing away money, planting trees in the desert for them to die."

The Great Green Wall is a top down, big government intervention that has little to no local buy-in and isn't sustainable without continued big government funding.

Not surprisingly, the funding has mostly dried up, and so has the land.

But by the same token, what is unsuitable for trees today doesn't have to be unsuitable a decade from now. Plant growth affects the climate. Retaining moisture, stabilizing day-night temperatures, retaining topsoil, changing surface albedo, triggering cloud formation, etc.

Ideally a mega-project is thousands of small projects being attempted at once in a way that is useful even if only a fraction of them work. Those 10% of places that worked could be used as a jumping off point for further efforts in the region, and in all cases people learned valuable agriculture skills they can take with them for the rest of their lives.
