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.

AFAIK geothermal is not renewable, in other words, all of the underground heat is just stored there from the formation of earth, but once consumed, it doesn't regenerate.

That's why i'm not a big fan of geothermal.

That's like saying the Earth's core or the sun / solar is not renewable.

Earth's core's heat is renewable, but only in geological timescales. Not in the next 1000 years. Same as oil. That's why we don't count it as renewable: It's not renewable on a human timescale.

It's also not going to run out anytime soon.
