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.

There are geothermal solutions for geothermal features near the surface already. This article is about advances in deep geothermal solutions: 15,000+ feet of pipe, deep into the earth. Utilizing the falling cost of horizontal drilling equipment from the fracking industry, there are now solutions to drill 10,000 feet down, and 5,000 feet sideways to improve the likelihood of running into superheated rock. Currently, drilling will be limited to geothermally gifted areas of America, but may be able to expand to less fortunate areas as the technology improves and gets even less expensive.
