Don't worry. There's so much heat, we little humans could never affect any significant change /s
EDIT But seriously. I remember years ago going to a residential GT workshop encouraging private heat sink wells hosted by some boomer reformed hippies. When I asked if there were any studies on the effect of subsurface heat exchange on things like ground water temperatures or different subsurface materials one of the presenters waved it off saying it was probably fine and the other honestly admitted that they didn't know, and that that should probably give us pause before encouraging 200 homes in a square mile all sink wells.
this hole goes 5km out of 6.378km. So 0.1% of the way. Even if we drilled all over the surface (and see floor) it would make very little difference. There is just a lot of Earth and the heat conducts very slowly.
Atmosphere on the other hand is very thin and mostly concentrated close to surface (half is under 5km) so it's much easier for humans to fuck it up
I want to believe this. But it just seems like every generation of humans has their "would make very little difference" moment. When it comes to energy, it turns out there's just no such thing as a free lunch.
