Study: Stopping global warming only way to save Australia's Great Barrier Reef

Reducing pollution and curbing overfishing won't prevent the severe bleaching that is killing coral at catastrophic rates, according to a study of Australia's Great Barrier Reef. In the end, researchers say, the only way to save the world's coral from heat-induced bleaching is with a war on global warming.

Scientists are quick to note that local protection of reefs can help damaged coral recover from the stress of rising ocean temperatures. But the new research shows that such efforts are ultimately futile when it comes to stopping bleaching in the first place.

"We don't have any tools to climate-proof corals," said Terry Hughes, director of the ARC...
