Synopsis
Many readers will be astonished that the contribution of glacial melt can be just under 1% even in the higher Himalayas. The estimates of some other researchers are far higher. The new study suggests the other researchers have failed to distinguish between snowmelt and glacial melt.
Agencies
In a 2014 report ISRO had monitored 2,018 Himalayan glaciers between 2001 and 2011. It found that only 248 glaciers were retreating, 1,752 were stable and 18 were advancing.
The recent flash flood in Uttarakhand was widely called a “glacier burst” although glaciers are not balloons and do not burst. It has spurred renewed warnings that global warming threatens quick melting of the Himalayan glaciers, decimating flows in the Gangetic plain, causing desertification and devastating agriculture. Academics like Brahma Chellaney predict wars from ....

Key Highlights
In the next less than 15 years, the mountains of Himalayas bid adieu to the last of glaciers unless there is a drastic correction in use of fossil fuels and other factors affecting global warming.
A study revealed that this melting means runoff is 1.6 times greater than if the glaciers were stable, resulting in seasonal flooding and the creation of many glacial lakes that create a risk of catastrophic outburst floods. ....
