Cloud whitening How it works: The idea here is to use satellite-guided sailing ships to crisscross the oceans, constantly spewing a fine stream of sea mist into the clouds. Turns out particles, in this case the salt in the sea mist, will cause clouds to become denser, reflecting more sunlight back into space and keeping the planet cooler. Each ship would cost $2 or $3 million, making the entire program cost just a few billion dollars. About 1500 ships would be needed to maintain current temperatures, according to John Latham, a scientist at the National Center for Atmospheric Research. clipped from money.cnn.com Space-based Frisbee deflectors How it works: Deflect the sun's rays with a cluster of translucent disks, each two feet in diameter, placed in orbit between the earth and the sun. clipped from money.cnn.com A permanent haze clipped from money.cnn.com Carbon-sucking machines clipped from money.cnn.com Ocean seeding clipped from money.cnn.com clipped from money.cnn.com clipped from money.cnn.com
