Saving Our World: How a last-ditch ‘planet-hacking’ plan could keep Earth habitable for longer

Some think that as a last resort, we may need to temporarily cool the planet by modifying the skies. It wouldn’t solve the problem, but it might buy us time. This technology, called solar geoengineering, is so controversial that some experts think it could lead to global war. But just in case, a team of researchers at Harvard is planning to conduct one of the first outdoor geoengineering experiments."
