for around half of the extra hurricane-fueling warmth in the
waters of the tropical North Atlantic in 2005, while natural
cycles were only a minor factor, according to a new analysis by
Kevin Trenberth and Dennis Shea of the National Center for
Atmospheric Research (NCAR). "The global warming influence
provides a new background level that increases the risk of
future enhancements in hurricane activity," Trenberth says. The
study appears 27 June in Geophysical Research Letters, published
by the American Geophysical Union. The study contradicts recent
claims that natural c
