Great Barrier Reef: 2/3 damaged in 'unprecedented' bleaching - BBC News

Unprecedented coral bleaching in consecutive years has damaged two-thirds of Australia's Great Barrier Reef, aerial surveys have shown. The bleaching - or loss of algae - affects a 1,500km (900 miles) stretch of the reef, according to scientists. The latest damage is concentrated in the middle section, whereas last year's bleaching hit mainly the north. Experts fear the proximity of the two events will give damaged coral little chance to recover.
