The Jorge Montt glacier in southern Chile is melting at a rate of a kilometer (0.6 miles) per year, making it one of the world's most visible milestones of global warming, according to researchers.
Chile's Center for Scientific Studies (CECs) said Wednesday that several glaciers in the country's south have shrunk because of global warming but that the 454-square-kilometer Jorge Montt is one of those shrinking the fastest.
The withering glacier is part of the 13,000-square-kilometer (5,020 square mile) Southern Ice Field, the third largest frozen landmass after Antarctica and Greenland.
During the 1990s, the glacier retreated some seven kilometers, but its rate of melting has "accelerated," releasing an increasing number of icebergs into the fjord where the glacier lay, according to Andres Rivera, of the CECs.
The latest study of the glacier took place between February 2010 and January of this year, during which two stationary cameras timed to shoot four times a day took some 1,445 pictures of the glacier.

Simultaneous ice melt in Antarctic and Arctic
Bremerhaven, Germany (SPX) Dec 06, 2011
The end of the last ice age and the processes that led to the melting of the northern and southern ice sheets supply basic information on changes in our climate. Although the maximum size of the ice sheet in the northern hemisphere during the last ice age is relatively well known, there is little reliable data on the dimensions of the Antarctic ice sheet.
