Senior scientists at the Wadia Institute of Himalayan Geology (WITG) has rejected the Global Warming Theory and told that the Himalayas are quite safer zone on earth, where Global Warming has no role in controlling the conditions.
In an exclusive chat with HT, Director WIHG Dr AK Dubey has said that the conditions of Himalayas are controlled by the winter snowfall rather than external factors like much hyped Global Warming. He told that for a concrete result, at least 30 years of continuous research with steady outcome is needed to confirm the actual impact.
"According to a data for over 140 years available with a British weather observatory situated in Mukteswar (2311m) in Almora has actually revealed that temperature in that region witnessed a dip of .4 degrees," he said.
Since 1991, the institute is monitoring the Himalayas extensively with focusing the glacial studies and last twenty year data has never witnessed a continual retreat. Sometimes, the recession rates have gone up but on an average the rate is very much safer, he added.
Whatever predictions about Himalayas are being made are based on short-term studies conducted on glaciers, which have no comparison with Himalayan Glaciers, he told. "Our glaciers are giant high altitude glaciers above 4000m altitude with a permanent temperature below 20 degrees Celsius. And has no comparison with the Alps Glaciers or Alaskan Glacier which are at sea level," he said.
Dr. DP Dobhal, eminent glaciologist added that however there is a change in climate in terms of shrinking of winter period but still a lot is dependent upon the snowfall occurs. Currently the rate of recession is in between 16-20 meters a year for glacial retreat in Himalayas, whereas 30 percent of the glaciers are more than 10km in length, he said.
