A study from the University of Hawaii and others says the seaweed is spreading more rapidly than...

Bleaching Hits Great Barrier Reef Like Never Before

With warmer temperatures, deadly problem is 'more widespread than ever'

(Newser) - An aerial survey of the Great Barrier Reef shows coral bleaching is sweeping across the area off the east of Australia for the third time in five years. Bleaching has struck all three regions of the world’s largest coral reef system and is more widespread than ever, scientists from...
