"Mass Coral Bleaching Cast Shadow Over Future Of Great Barrier Reef"

"Mass coral bleaching has destroyed at least 35 percent of the northern and central Great Barrier Reef, Australian scientists said on Monday, a major blow to the World Heritage Site that attracts about A$5 billion ($3.59 billion) in tourism each year.

Australian scientists said the coral mortality figure will likely rise as some of the remaining 65 percent of coral in the northern and central reefs fails to recover from bleaching.

The report casts a shadow over the long-term prospects of the Great Barrier Reef against a backdrop of climate change and scientists said UNESCO may reconsider its decision not to put the World Heritage Site on its endangered list."
