Global warming: Researchers document profound cascading ecological effects as Rocky Mountain snowpack diminishes

A steady decline in Rocky Mountain snowpack the past few decades has led to a classic cascading ecological effect, with "powerful" shifts in mountainous plant and bird communities, according to scientists with the U.S. Geological Survey http://www.usgs.gov/ and the University of Montana http://www.umt.edu/future.aspx .

"This study illustrates that profound impacts of climate change on ecosystems arise over a time span of but two decades through unexplored feedbacks," said USGS director Marcia McNutt. "The significance lies in the fact that humans and our economy are at the end of the same chain of cascading consequences."
