'Cloud brightening' experiment may help cool Great Barrier Reef

By Stuart McDill LONDON (Reuters) - Researchers trying to save the Great Barrier Reef are attempting to cool the unusually warm sea temperatures using ‘cloud brightening’, a geo-engineering technique designed to reflect more of the sun’s rays away from the Earth. The team are spraying microscopic sea water droplets into the air over the reef, which creates more cloud cover and more shade in an effort to save the health of one of the world's most important marine...
