Global warming surpassed natural cycles in fueling 2005 hurricane season, NCAR scientists conclude
BOULDER– Global warming accounted 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 study will appear in the June 27 issue of Geophysical Research Letters, published by the American Geophysical Union.
“The global warming influence provides a new background level that increases the risk of future enhancements in hurricane activity,” Trenberth says. Continue reading
