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:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

hydro? geothermal?
I think there's some new initiatives for deeper drilling to make geothermal feasible in most areas now. Would be great because geothermal is probably the best energy source available to us.
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.
The risks are pretty minimal, especially after the drilling & building is done. And in exchange you get basically unlimited free base load safe energy. Wind and solar still have issues with the materials used and their recycling, but I suppose that's more of a problem for "other people".
