April 22, 2016 Great Barrier Reef More Than 90% Bleached ----------------------------------------- Meanwhile, scientists say the Great Barrier Reef is more than 90 percent bleached, a result of warming ocean temperatures due to climate change. Severe reef bleaching kills coral, which is home to a quarter of all marine species.
