Far too late for that. It's going to take big industrial solutions, like the "L1 Space Parasol" (scary, better)[0] or the "Superdust Chemical Injection into the Upper Atmosphere" (less scary, dumber[1]). Or some scary bioengineering, which might be even dumber-er.

Other techbro geniuses have talked up giant pumpships just blasting water in the air, but these techbro geniuses couldn't teach a community college intro physics, much less attempt to thermodynamically balance a planet's gas exchange. It's a dumb idea on almost every level, which is impressive in its own way.

The investment upside here is basically limitless. If you make something livable, you can charge rent to everyone there. Wreck the planet, save some spots, charge rent. King of the world. Oh don't want to pay your rent? Oops now you're cooking in your own juices. I'm baffled that this isn't already a thing. But the masters of industry have a hard time doing big real things these days, so who knows. No no go ahead build your titanic ornamental fountain that'll work great.

It'll come down to war, and then hucking nukes, in the end.

[0] Something that stops working on its own when not maintained is probably a good design goal here.
