Simon Bolivar, 63, walks towards his plot of land where he grows corn and potatoes in Huaraz, Peru, Wednesday, Dec. 3, 2014. Villagers claim that due to global warming, each year there are more frost out of season and their crops are affected. Peru's glaciers have lost more one-fifth of their mass in just three decades, and the 70 percent Peru's 30 million people who inhabit the country's Pacific coastal desert, depend on glacial runoff for hydropower and to irrigate crops, meaning their electricity and long-term food security could also be in peril. Higher alpine temperatures are killing off plant and animal species in cloud forests and scientists predict Pacific fisheries will suffer. (AP Photo/Rodrigo Abd)
