NEW DELHI: Majority of glaciers in India including Gangotri are melting at varying rates ranging from five to 20 metre per year, the Government today told the Lok Sabha.
“The studies carried out by ISRO, Wadia Institute of Himalayan Geology (WIGH) Dehradun and other institutions have revealed that majority of the glaciers are retreating (melting) at varying rates from 5-20 metre per year,” Environment Minister Anil Madhav Dave said in a written reply.
He said Gangotri is one of the largest glaciers (30 km long) of Uttarkahand followed by Satopanth glacier (14 km) and both of the glaciers are “retreating” but “not at an alarming rate”.
He said the studies carried out on melting of glaciers by the in-situ measurements as well as remote sensing data indicate that the rate of retreat is “not uniform” for all glaciers.
Giving an example, Dave said Dokriani glacier in Bhagirathi basin is retreating between 15 and 20 metre per year since 1995 whereas Chorabari glacier in the Alaknanda basin is retreating 9-11 metre per year (2003-2014).
