Confirmed decrease of the world’s glacier mass balance

The evident Vernagtferner glacier melting, Tirol - Austria. Since the start of annual mass balance measurements in 1968, the ice loss cumulated to almost 12 metre w.e., with a thickness loss of about 0.5 metre w.e. during 2005.
New data published by the World Glacier Monitoring Service (WGMS) confirms the trend in accelerated ice loss during the past two and a half decades and brings the average thickness loss since 1980 of the 30 reference glaciers of 9 mountain ranges (Cascades, Svalbard, Andes, Alaska, Scandinavia, Alps, Altai, Caucasus and Tien Shan) at about 9.6 m (water equiv.). Tentative figures indicate a further thickness reduction of 0.7 m and 0.6 m during 2004 and 2005, respectively.

lately i am reaching the conclusion that the problem is getting worse not linear but exponential.

Thus, no matter what we do, the changes cannot be overturned.

Overturned no, but subdued maybe yes...
