no more reef

The Great Barrier Reef could be dead in 20 years unless there is a drastic reduction in greenhouse gas emissions, a marine biology expert said on Friday.

Rising sea temperatures were bleaching the coral and causing it to die, said Professor Ove Hoegh-Guldberg of the Australian Research Council for Excellence for Coral Reek Studies.

At the same time, increasing levels of carbon dioxide in the atmosphere were turning the world’s oceans more acidic and preventing corals form forming their limestone skeletons, he said.
