The World’s Largest Tropical Ice Field is Vanishing

The Quelccaya Ice Cap in the heart of the Peruvian Andres, is the largest tropical body of ice in the world. The ice cap is at an average altitude of 5,470 meters (18,600 ft) and spans an area of 44 square kilometers (17 miles).  As the ice cap is retreating, it is exposing almost perfectly preserved plant specimens dating back 5,200 year, indicating that it has been more than 50 centuries since the ice cap was smaller than it is today. According to recent research, one of the glaciers in this ice cap, the Peruvian Qori Kalis, like the snowfields of Africa’s Mount Kilimanjaro, is rapidly melting and could soon vanish completely (comparisons with previous mapping showed 33% of Mount Kilimanjaro’s ice had disappeared in the last two decades – 82% since 1912)
