Extreme melt season leads to decade-long ecosystem changes in Antarctica's Dry Valleys

Extreme melt season leads to decade-long ecosystem changes in Antarctica's Dry Valleys 08/07/2017 12:35 PM EDT An abnormal season of intense glacial melt in 2002 triggered multiple distinct changes in the physical and biological characteristics of Antarctica's McMurdo Dry Valleys over the ensuing decade, new research funded by the National Science Foundation (NSF) shows. The findings suggest that abrupt, short-lived climate events can cause long-term alterations in polar regions that unfold over the span of several years and subsequently change the overall trajectory of an ...
