alt Hacker NewsWhat about solar shades? Seems like a relatively quick and easy way to regulate solar input. It's nice too because you can quickly remove it if necessary.

Only becomes viable if you have things like Starship online and fully operational, with launch rates at the level of Falcon 9 today. At the minimum.
Still a more viable option than bringing greenhouse gas emissions into the negatives globally, by the way. But that's a low bar. Nuking the ocean floor is probably a better call.

Reducing sunlight to the surface means we lose solar power effectiveness and we need to use more power for artificial lighting to grow plants.

How long would a single cargo-load of shades have to be operational just to offset the amount of CO2 emitted by its launch?
