Glaciers shrinking faster

The BBC reports on new data available from the World Glacier Monitoring Service (http://www.wgms.ch/) which suggest that the rate of glacier shrinking due to global warming is now three times as fast as it was in the 1980's. The photo (from O. Gruber, H. Rentsch and M. Siebers from the Bavarian Academy of Sciences and Humanities) was taken in 1968 at Vernagtferner in Austria. Photos taken at the same location in 1912 and 2003 are shown in the BBC News item and demonstrate the huge shrinkage that has occurred over the last century. During 2005 alone, the glacier was reduced in thickness by more than 0.5m.
