Heat doesn’t go up. Hot air rises because it’s less dense than cold air. You know what’s less dense than hot air though? Vacuum. That’s a good thing, though, because we don’t want to be hemorrhaging atmosphere.

Even if we could build a physical heat sink sticking out of the atmosphere somehow, it would be less protected from solar radiation than anything inside the atmosphere, so if it were facing the sun it probably wouldn’t work.

Even if we had the resources and like, enough readily available materials on Earth to make some sort of retractable heat sink sticking out of the night-side of the planet, it’d probably require more energy consumption to create than would be worth it.

Probably the best way to cool things down is to quit burning so much shit and quit knocking forests down.

I love reading, but the moment an author tries to guilt me into reading their particular viewpoint as though I’m just a slave of the system if I don’t, I check out. I have better things to do, and this person doesn’t have any right to my time.
