Scientists Propose Creating Clouds to Slow Warming

As unusually harsh droughts continue to grip much of the United States, and new record-breaking weather events seem to strike with increasing regularity, the push to find solutions to global warming has never been more urgent -- so much so that even the most unconventional ideas are being given a second look. Scientists from the University of Washington recently unveiled a new take on an old proposal to cool the Earth by artificially producing cloud cover over swaths of ocean to reflect away light, part of a process known as 'marine cloud brightening'. The concept is actually fairly simple: a fleet of boats equipped with sprayers large enough to project particles of sea-salt into the atmosphere where they would facilitate the formation of clouds. The resulting cloud cover, if dense enough, could to reflect enough heat-producing sunlight back into space to lead to cooling a...
