Scientists say global warming causing more violent hurricanes

A new study reports stronger links between human-caused global warming and rising ocean temperatures -- a key factor in the development and growth of hurricanes.

The new study was done by researchers at Lawrence Livermore lab in California.

''We've now learned that the human-induced buildup of greenhouse gases in the atmosphere appears to be the primary driver of increasing hurricane activity,'' Robert Corell, an oceanographer and a researcher for the American Meteorological Society, said during a press conference to promote the study.

The findings were published Monday in the latest issue of the Proceedings of the National Academy of Sciences.
