Even before last year, I had a look at histogram showing the nos of US hurricanes over time; seemed to me the frequency had become fair bit higher than a cursory look at the cycles would predict.

Global warming accounted for about half of the extra hurricane-fueling warmth in Atlantic waters off the United States in 2005, while natural cycles were smaller factors, according to a study released Thursday by the National Center for Atmospheric Research.

“The global warming influence provides a new background level that increases the risk of future enhancements in hurricane activity,” co-author Kevin Trenberth wrote in the study.

A statement issued by the center said that the study “contradicts recent claims that natural cycles are responsible for the upturn in Atlantic hurricane activity since 1995. It also adds support to the premise that hurricane seasons will become more active as global temperatures rise.”
