By Mark Schrope CORAL reefs will be crippled if carbon dioxide levels increase as projected this century, say researchers in the US who have studied the impact of changing ocean chemistry on corals in the Biosphere 2 facility in Arizona. “I think this is fairly urgent,” says Robert Buddemeier, a coral researcher with the Kansas Geological Survey in Lawrence. “It’s the first really documented negative biochemical impact of rising CO2,” he says. Coral polyps use calcium and carbonate from surrounding waters to build their skeletons, which become the framework of coral reefs. But CO2, a weak acid,
