Century of Data Shows Intensification of Water Cycle but No Increase in Storms or Floods
March 15 — A review of the findings from more than 100 peer-reviewed studies shows that although many aspects of the global water cycle have intensified, this trend has not consistently resulted in an increase in the frequency or intensity of tropical storms or floods over the past century. (United States Geological Survey press release) More

Study Offers Preview of Ice Sheet Melting, Rapid Climate Changes
