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.

In the realm of crazy ideas, why not flood parts of the Sahara? Build a canal from the closest sea and just let it drain into there. There are also areas in Australia that were one great lakes that could also have a canal or two built to them from the ocean and flooded. Given the temperature in those places, it might make enough condensation to rejuvenate those and surrounding areas with the precipitation.

Mostly because it's expensive and the benefits unclear. This one had a bunch of modeling work done around the proposed intervention so we can know what it's likely to accomplish

There has been some talk about moving water around in Australia. This and others like it.
