Melbourne FL (SPX) Jul 08, 2010 Improving the quality of local water increases the resistance of coral reefs to global climate change, according to a study published in Marine Ecology Progress Series. Florida Institute of Technology coral reef ecologist Robert van Woesik and his student Dan Wagner led the study, which provides concrete evidence for a link between environmental health and the prospects for reefs in a rapidly changing world. Van Woesik and his team showed that when waters in the Florida Keys warmed over the last few summers, corals living in cleaner water with fewer nutrients did well. On the other hand, corals in dirtier water became sick and bleached. "Regulating wastewater discharge from the land will help coral reefs resist climate change," said van Woesik. "In the face of climate change and ocean warming, this study gives managers hope that maintaining high water quality can spare corals."

Whiter Clouds Could Mean Wetter LandPalo Alto CA (SPX) Jul 02, 2010 One proposed emergency fix to halt global warming is to seed clouds over the ocean to make them more reflective, reducing the solar radiation absorbed by the Earth. But the scheme could also change global rainfall patterns, raising concerns of water shortages on land. A new study by the Carnegie Institution, in collaboration with the Indian Institute of Science, suggests that altered atmos ... read more |
