A view of a lake filled with glacial melt water is seen in Huascaran National Park in Huaraz, Peru on September 18, 2013. The nearby Pastoruri glacier is one of the fastest receding glaciers in the Cordillera Blanca mountain range according to a 2012 paper by the University of Texas and the Huascaran National Park. Peru is home to 71 percent of the world’s tropical glaciers, which are a source of fresh water for millions. Because of global warming, 22 percent of the surface area of Peruvian glaciers has disappeared in the past 30 years alone, according to The World Bank.
