Scientists say Perito Moreno, which for decades defied trend of glacial retreat, now rapidly losing mass
One of the few stable glaciers in a warming world, Perito Moreno, in Santa Cruz province, Argentina, is now undergoing a possibly irreversible retreat, scientists say.
Over the past seven years, it has lost 1.92 sq km (0.74 sq miles) of ice cover and its thickness is decreasing by up to 8 metres (26 ft) a year.
