Brighter World (1x4)

:

John Latham, an atmospheric physicist based at the National Center for Atmospheric Research in Colorado, and Stephen Salter, an Edinburgh University engineer, believe that by changing the size of water droplets in a cloud they can increase the cloud's ability to reflect the sun and stop global warming. Their vision is to build a flotilla of ships that will roam the world's oceans and seed clouds with minute particulates.
