NEW DELHI: While the precise cause of ‘calving’ of a glacier in Uttarakhand is yet to be determined, a group of specialists will go to the site on Monday to learn the factors for the disaster.
Prima facie, international warming and climate modification appear to be the aspects. The Nanda Devi biosphere reserve, where the glacier is located, hasn’t been evaluated yet, other than through remote sensors.
While the occurrence is a strong suggestion of the 2013 flash floods, experts point out that the present occurrence is different from the previous one, which occurred due to a weather occasion– a cloud burst.”In this case, there has actually not been any abnormally high rains and even extreme snowfall. It is also not clear what sort of lake was there and how it was breached at the mouth. In the beginning evaluation, a weather condition event is ruled out. Only closer examination will assist understand the causes plainly,” Vinit Kumar, Scientist at the Wadia Institute of Himalayan Geology specialising in glaciology, told ET.Kumar and his group will be going to the site on Monday.The occurrence, however, has actually when again brought into focus environment modification and increased human activity in the environmentally sensitive region. The Char Dham roadway growth job in addition to numerous hydel projects on the upper reaches of the Himalayan rivers in Uttarakhand are being hotly debated and the matter is presently in the Supreme Court.Prof AP Dimri of JNU’s School of Environment Sciences and a lead scholar on the National Mission on Himalayan Studies said: “It is plainly not linked to a weather condition occasion like 2013. Total impact of worldwide warming, particles aggregation and numerous factors weighing in are most likely to have some function to play.”Dimri said while developmental activities are bound to have some impact on the overall ecology, tiny hydel tasks are usually seen in conjunction with the ecology. “The larger dams obviously have impact as they cause more precipitation and so on. Nevertheless, in this case there was rains, so other elements seem at play,” he added.Mohd Farooq Azam, assistant professor, glaciology and hydrology, IIT Indore, agreed with Kumar and Dimri and said: “Climate change-driven irregular weather condition patterns like increased snowfall and rainfall, warmer winters has actually led to the melting point of a great deal of snow. The thermal profile of ice is increasing– earlier the temperature of ice varied from -6 to -20 degree C; it is now -2, making it more vulnerable to melting.”
