Not sure if ground source heat pumps (which would heat the ground rather than the air in the summer in AC mode) would make a meaningful difference or not.

I worry that this will just displace the problem for a generation, and eventually, just as the atlantic ocean has warmed to fucking jacuzzi levels, eventually we won’t be able to pour more heat into the ground.
