By Kurt Kleiner in Washington DC HURRICANE Bonnie did more than batter the Carolinas with heavy rains and winds last week. It also siphoned tonnes of carbon dioxide from the Atlantic Ocean into the atmosphere. Nicholas Bates of the Bermuda Biological Station for Research, with colleagues at the University of Southern California in Los Angeles, noticed this previously unknown effect of hurricanes after observing Hurricane Felix in 1995 passing Bermuda. In a paper in Nature this week (vol 395,p 58), they report that Hurricane Felix increased the amount of CO2 released into the atmosphere from the Sargasso Sea by about 55 per cent in the summer of 1995, by cooling the surface waters and so reducing the amount of the gas they could hold. Strong winds and waves encouraged the release of the gas into the atmosphere. Some climatologists believe global warming caused by CO2 in the atmosphere will increase the number of hurricanes, or at least make them more intense. So by encouraging global warming,
