Summary

Build Earth Some Sunglasses

Description

When you're lounging on the beach on a sunny day with the sun's hot rays beating down on you, you may try to keep out the glare with a pair of sunglasses or a hat. Some scientists have proposed taking a similar strategy with our warming planet: putting a ring of sunlight-scattering particles or micro-spacecraft in orbit around the equator. The idea is that the ring would reduce the amount of solar radiation hitting the planet and counteract some of the warming induced by greenhouse gases. The wild idea would also be an expensive one, with a potential price tag in the trillions of dollars.
