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.

Unfortunately, that’s just not possible everywhere. For instance, where I live the water table is like 6 inches below the ground. Pretty much every house here has a crawlspace foundation. The few that do have basements pretty much all have mold issues and need sump pumps, etc.
Sounds like a good source for water cooling! Dig a small well and pump the water around you to cook your room.
Not sure how effective this really is, should get some amount of cooling and have been curious to try it sometime.
That's the issue with high wet bulb conditions: they are too hot and humid to allow for evaporative cooling to work.
Good news, it isn't evaporative. It relies on the ground being cooler than the air.
Oh, you mean geothermal cooling. Yes, some buildings use that for heating/cooling by using vertical wells or buried horizontal loops coupled with heat pumps. It's fairly green, though can be an expensive investment up front if one needs to use vertical wells due to lack of real estate. It's still air conditioning, just coupled to underground water as a heat sink instead of outside air.
I could think of better uses lol
