Photo Friday: Visible Glacier Shrinking in Puncak Jaya

Even though mountain peaks near the equator have supported glaciers for thousands of years, they have retreated significantly in the last century because of climate change. Many tropical glaciers have lost more than half of their volume with the rapid development of global industry. Puncak Jaya, the earth’s highest island peak in Indonesia, holds the last glaciers in the tropical Pacific. Back in 1989, five ice masses sat on the slopes of Puncak Jaya. But by 2009, two of the glaciers, Meren and Southwall, were gone. The other three, Carstenz, East Northwall Firn, and West North Wall Firn, have retreated dramatically since the 1970’s, according to satellite imagery analyzed by Joni L. Kincaid and Andrew G. Klein, from the department of Geography in Texas A&M University. The Meren Glacier melted away sometime between 1994 and 2000.
