04 Aug 2015: Study Finds Glaciers Melting
At Unprecidented Rates Around the Globe

Glaciers around the globe are melting at unprecedented rates, according to an analysis of data spanning 120 years by researchers at the University of Zurich. The team compared glacier data collected between 2001 and 2010 with measurements, aerial and satellite photos, written accounts, and historical depictions from the previous century. On average, glaciers are currently losing between 0.5 and 1 meter of ice thickness each year, the researchers found — two to three times more than glaciers were losing on average in the 20th century. Although the team analyzed exact measurements from a few hundred glaciers, they say that field- and satellite-based observations of tens of thousands of glaciers around the world confirm their findings on a much larger scale. Intense ice loss over the past two decades has made glaciers unstable in many regions, the researchers say, and these glaciers will suffer further ice loss, even if the climate stabilizes.
