Mystery Glaciers Growing as Most Others Retreat

from National Geographic News

Two South American glaciers are displaying strange behavior for the times: They're growing.

Most of the 50 massive glaciers draped over the spine of the Patagonian Andes are shrinking in response to a global warming, said Andrés Rivera, a glaciologist at the Center for Scientific Studies in Valdivia, Chile.

But the Perito Moreno glacier in Argentina and Pio XI glacier in Chile are taking on ice, instead of shedding it. "What is happening ... is not well understood," Rivera said.
