No Time Left to Adapt to Melting Glaciers http://apocadocs.com/s.pl?1325012334
The water supplied by the glaciers of the Cordillera Blanca, vital to a huge region of northwest Peru, is decreasing 20 years sooner than expected, according to a new study.
Water flows from the region's melting glaciers have already peaked and are in decline, Michel Baraer, a glaciologist at Canada's McGill University, told Tierramérica. This is happening 20 to 30 years earlier than forecasted... When glaciers begin to shrink in size, they generate "a transitory increase in runoff as they lose mass," the study notes.
However, Baraer explained, the water flowing from a glacier eventually hits a plateau and from this point onwards there is a decrease in the discharge of melt water. "The decline is permanent. There is no going back."
