israeli scientists predict the world ' s coastal reefs could begin to weaken in as little as 30 days from now . they show the oceans are becoming increasingly acidic as they soak up manmade emissions of carbon dioxide . the central university of jerusalem researchers predict this will make it difficult for most reef organisms to produce skeletal and other hard materials . the team ' s work on algae in the black sea indicate a tipping level will be reached in between 30 and 70 years . then the forces of erosion eating away at corals will outstrip the organisms ' ability to make the reefs .
the coral organisms are impaired by the desertification of oceans .
