Global Warming: 1,600 Years of Ice in Andes Melted in 25 Years
Providing one of the signs of global warming, glacial ice in the Peruvian Andes has started melting. A structure that took 1,600 years to build has fallen into the grip of high temperatures and melted within 25 years.
The research has been conducted by Lonnie G. Thompson, the Ohio State University glaciologist. According to him, his team has worked from time to time on the Quelccaya ice cap for decades. Findings have been published in a paper that has been released online.
Global warming is one of the results of man-made activities. This recent report has highlighted that the problem of global warming has reached its peak. This time the proof has been provided by margins of the Quelccaya ice cap in Peru.
It is the world's largest tropical ice sheet. Rising temperature levels have uncovered the areas that have taken years to build. The findings have been obtained by the scientists after dating those plants, using a radioactive form of carbon in the plant tissues that decays at a known rate. This methodology has given scientists a way of deciphering the age of Peuvian Andes.
The research has further been expanded to study the long-dead plants budding from the melting ice at the edge of Quelccaya.
