Recent studies armed with digital elevation maps and satellite imaging says that 32 glaciers surrounding the Mt.Everest are losing their ice mass to lakes, which might create havoc leading to killer floods as happened on 1985 Dam burst in Nepal.
Himalaya’s, home to a quarter of 198,000 total glaciers on our planet. The snow packed Asian ridges contain 9 of the 10 highest peaks on our planet, but recent studies break the ice to expose the unfortunate truth that some glaciers surrounding the higher peak, Mount Everest is suffering a meltdown. Thanks to changing climatic variations, nature itself is deforming and adding heat to fire the melting glaciers might result in a killer flood reminding the one that wrecked the Nepal in 1985. Around 32 glaciers have been so far identified, that is losing more ice mass than landlocked glaciers, into lakes. If this continuous then the added water might result in dam bursts and killer flood which would affect the surrounding countries like India, China, Bhutan and Bangladesh.
Decreased snowfall and increasing Avg. temperature is what scientists hold responsible for this action, but the ultimate cause shall be pointed to humans and their fight for flourish. In 1985 when the debris dam at Dig Tsho failed it send havoc down to Nepalese lives by spilling millions of cubic meters of water on the village of Ghat destroying houses, farm lands, bridges and a new hydropower plant. In the light previous disaster, the Nepal government had already taken all necessary precautions by draining a portion the Imja Tsho Lake to contain the flood rush. There is also a possibility that the lake water is eroding the glaciers, cleaving the bottom to release ice mass which gradually melts into the lake.
A team of researchers and glaciologists have been studying the Himalayan glaciers using the satellite data and digital elevation map, comparing the heights of glaciers back in 2000 to that of on 2015. Nine lake terminating glaciers and 23 land-terminating glaciers were shortlisted to be melting down, where team compared the 15 years of data on ice mass, area, and height of glaciers. As per their estimation, the lake terminating glaciers are losing a whopping 32% more ice than a land-terminating, which had raised the alarm to take the matter seriously. With the advanced satellite imaging technique, more information can be pulled, which shall be used to compare the satellite images back in 1970 to understand the ice loss vs timeline.
