Australia | Great Barrier Reef suffers another mass bleaching

SYDNEY, Australia — A wide stretch of the Great Barrier Reef has been hit by a sixth mass bleaching event, the marine park’s authority said on Friday, an alarming milestone for the coral wonder that points to the continued threat of climate change and greenhouse gas emissions.

Government scientists who used helicopters and small planes to survey 750 separate reefs across hundreds of miles last week found severe bleaching among 60 percent of the corals.
