Tom Rodriguez, a mountain guide and volunteer at Peru's Glaciology Unit, stands at the leading edge of the Pastoruri glacier along the Climate Change Route in Huaraz, September 19, 2013. The 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% of the world's tropical glaciers, which are a source of fresh water for millions, but 22% of the surface area of Peruvian glaciers has disappeared in the past 30 years alone, according to The World Bank. Environmental issues are under the spotlight during a working group of the Intergovernmental Panel on Climate Change, who are meeting in Stockholm from September 23-27.
