Chilling Reality

The Disappearance of glaciers entire mountain ranges. as a  result of global warming, is a  very real possibility, according to the latest update of a United Nation- supported report of the state of the world glaciers. Issued every five years by the World Glacier Monitoring Service (WGMS) in Zurich, Switzerland, the report warns that the greenhouse effect brought on by human activity is leading to processes without precedent in the History of the earth.

 

The last five-year period of the 20th century has been Characterised by an overall tendency of continuous if not accelerated  glacier melting, says the WGMS 1995-2000 edition of the report fluctuations of Glaciers,  complied with the support  of the United Nations  Environment programme (UNEP). The two decades [from] 1980-2000 show a trend of  increasingly  negative balances with average annual ice thickness  losses of a few decimeters,  says the report.

 

The  observed trend of increasingly negative mass balances is consistent with accelerated global warming. Analysis of repeated inventories  shows that glaciers in the European Alps  have lost over 50% of their volume since the middle of the 19th century, and that  a further loss of roughly one-fourth the remaining  volume is estimated to have occurred since the 1970s.  With a realistic scenario of future atmospheric  warming. Almost complete de-glaciation of many mountain ranges could occur within decades, leaving only some ice on the very highest peaks, the report says.
