In Hot Water: Global Warming Takes a Toll on Coral Reefs Charles W. Schmidt Abstract
In 2005, months of unprecedented higher-than-normal water temperatures started a cascade of bleaching, disease, and death among corals in the Eastern Caribbean. Such events are increasing in frequency around the world and threaten these fragile ecosystems, which shelter a wealth of biodiversity and provide sources of food and pharmaceuticals. Researchers must determine how rising temperatures produce coral bleaching, the pathogens that cause disease in corals, and the environmental factors that foster disease outbreaks. Currently, scientists and coral reef managers are calling for increased protection for reefs from stressors such as pollutants, sewage, and sediment runoff, all of which can exacerbate the effects of warmer temperatures on corals.
