The MIT technology review: Scientists Consider Brighter Clouds to Preserve the Great Barrier Reef

For the last six months, researchers at the Sydney Institute of Marine Science and the University of Sydney School of Geosciences have been meeting regularly to explore the possibility of making low-lying clouds off the northeastern coast of Australia more reflective in order to cool the waters surrounding the world’s biggest coral reef system. 

During the last two years, the Great Barrier Reef has been devastated by wide-scale bleaching, which occurs as warm ocean waters cause corals to discharge the algae that live in symbiosis with them. Last year, as El Niño events cranked up ocean temperatures, at least 20 percent of the reef died and more than 90 percent of it was damaged.
