Al Jazeera's Teresa Bo reports from Peru's Cuzco region on the growing climate crisis. The inhabitants of South America's Andean mountains are seeing increasing instances of drought and disease, linked to warming temperatures. Peru began seeing cycles of El Nino - a warm pacific current that brings higher temperatures and rainfall - in 1998, and as the temperatures rose, diseases that were originally seen only in tropical areas spread to the mountains. Meanwhile, scientists predict that rising temperatures could spell the end for Andean glaciers, which provide water for 70 per cent of Peru.
