Bill Gates Funds Seawater Cloud Seeding, "the Most Benign Form of Geoengineering"

Bill Gates is getting serious about geoengineering. Back in January, after the failure of governments at the Copenhagen Climate Change summit to do anything serious, the billionaire former head of Microsoft announced he's give nearly $5 million of his fortune to fund research into geoengineering projects. Recently he announced his first concrete foray into the field: giving $300,000 to project that would spray seawater into the sky, seeding clouds that would hopefully block some of the sun's UV rays.
