Melting glaciers hype?


More food for thought on global warming hype, from Energy Probe:
Himalyan glaciers melting due to global warming is “hype,” state Indian geologists

Global warming is not causing Himalaya’s famous Siachen glacier to melt, state geologists R K Ganjoo and M N Koul of Jammu University’s Regional Centre for Field Operations and Research of Himalayan Glaciology. The geologists, who call claims that global warming is rapidly melting Siachen “hype,” reported their finding in “Current Science” after visiting the Siachen glacier to record changes in its snout last summer.
The Siachen Glacier, immediately south of a watershed separating China from the Indian subcontinent, lies in the glaciated portion of the Himalaya’s Karakoram range. Siachen is the longest glacier in the Karakoram and second-longest in the world’s non-polar areas.
Contrary to the claims of global warming doomsayers, Ganjoo and Koul found no abnormal melting; neither did they find the melting that was occuring to be attributable to man-made causes. The geologists also dismiss claims by global warming doomsayers that the glacier, in the current Holocene period that followed the last Ice Age, was covered in 600-metre thick ice.
“To our surprise, the Siachen glacier valley does not preserve evidences of glaciation older than mid-Holocene, suggesting that the glacier must have advanced and retreated simultaneously several times in the geological past, resulting in complete obliteration and modification of older evidences,” they stated.
There is sufficient field and meteorological evidence from the other side of Karakoram mountains that corroborate the fact that glaciers in this part of the world are not affected by global warming, they said.
As reported in Current Science: Overwhelming field geomorphological vidences suggest poor response of the Siachen glacier to global warming. The snout of the Siachen glacier of 2008 has retreated by about 8–10 m since 1995 dences. There are sufficient field and meteorological evidences from the other side of the Karakoram mountains that corroborate the fact that glaciers in this part of the world are not affected by global warming. The field studies
from other glaciers in India also corroborate the fact that inter- and intra-annual variations in weather parameters have more impact on the change in glaciers of NW Himalayas, rather than any impact due to global warming.
Ganjoo added that the east part of the Siachen glacier showed faster withdrawal of the snout that is essentially due to ice-calving, a phenomenon that holds true for almost all major glaciers in the Himalayas and occurs irrespective of global warming.
