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.

Analysis of six extreme heatwaves found that when temperature and humidity were accounted for, all were potentially deadly for older people

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.

to cook your room

I could think of better uses lol
