Be cheaper to have a largish silverish baloon aligned to block the sun at altitude, also knowing how we do freezing currently it will on balance not add more warm air.
- emiliobumachar 14y agoI did not do the math, but I think a huge, huge object would be needed in order to shadow even 1% of the Earth.
