Too bad we can't create a dyson sphere that we could partially close to limit sun exposure enough to refreeze parts of the planet as needed and also use the sphere to power everything on earth.
- g_simonsson 9y agoThis reminds me of the Sun-Earth-L1 Lagrangian point, where we have deployed several spacecrafts: https://en.wikipedia.org/wiki/Lagrangian_point#Spaceflight_applications https://en.wikipedia.org/wiki/Lagrangian_point#Spaceflight_a... An international effort could easily deploy reflective materials here to reduce solar radiation on Earth. Though I wonder how much it would cost to achieve even a 0.01% reduction in radiation, as well as what material would be most cost-effective to deploy.

- chr1 9y agoThere are easier methods to control the climate. E.g solar updraft towers can be used to create cloud cover, and to increase convection in the atmosphere.
