Warmer Atlantic worsens hurricanes

WASHINGTON – When the water in the hurricane breeding grounds of the Atlantic warms one degree in the dead of summer, overall hurricane activity jumps by half, according to a new study.

Scientists have long known that hurricanes get their enormous energy from warm waters, so the warmer the water, the more fuel a storm has to either start up or get stronger. The study calculates how much storm frequency and strength is due to warmer sea water, said author Mark Saunders, professor of climate prediction at the University College London.


Saunders found a distinct numerical connection between the ups and downs of water temperatures and how nasty hurricane season gets. That helps explain why hurricanes have been so much worse in the past dozen years, and even why 2007
