Fifth of corals dead: only emission cuts can save the rest, says IUCN

The world has lost 19 percent of its coral reefs, according to the 2008 global update of the world's reef status. The report, released by the Global Coral Reef Monitoring Network, shows that if current trends in carbon dioxide emissions continue, many of the remaining reefs may be lost over the next 20 to 40 years.
