Andean glaciers have shrunk 30 and 50 percent with climate change.Climate change has shrunk Andean glaciers between 30 and 50 percent since the 1970s and could melt many of them away altogether in coming years, according to a study published in the journal The Cryosphere.
Andean glaciers, a vital source of fresh water for tens of millions of South Americans, are retreating at their fastest rates in more than 300 years, according to the most comprehensive review of Andean ice loss so far.
The study included data on about half of all Andean glaciers in South America, and blamed the ice loss on an average temperature spike of 0.7 degree Celsius (1.26 degrees Fahrenheit) over the past 70 years.
“Glacier retreat in the tropical Andes over the last three decades is unprecedented,” said Antoine Rabatel, the lead author.
