Australia’s Great Barrier Reef has lost more than half its coral cover since 1985, according to a new study published in the Proceedings of the National Academy of Sciences. The loss has been spurred by a combination of factors including hurricanes, coral-eating starfish and coral bleaching. The paper is the most comprehensive survey of a…
