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.

I'm picturing a Corsi-Rosenthal box with automotive radiators connected in series instead of air filters! The inlet hooked to a sink, and the outlet hooked to the drain. Heat losses would be introduced at the well's pump, and at the box fan motor. As long as nothing leaks, the only things to worry about would be the added power consumed, the added wear on the well pump, and the well water's rate of replenishment. Oh, and the condensation which may collect on the radiators. An interesting DIY idea. I wonder if anyone has already tried it.

Sounds like you are combining both ideas somehow? The Corsi-Rosenthal box radiator in your sink would absolutely work. Though I don't know how much water you would be going through for it.

If you instead used a closed loop and pumped water through the ground to cool off then the only thing going is the pump and fan.

Condensation is a possible issue, tray and bucket to collect it?
