Recently, the Ministry of Jal Shakti has released the Glacial Lake Atlas of Ganga Basin.
The information on glacial lakes like their type, hydrological, topographical, and associated glaciers are useful in identifying the potential critical glacial lakes and consequent GLOF risk.
According to National Disaster Management Authority, glacial retreat due to climate change occurring in most parts of the Hindu Kush Himalaya has given rise to the formation of numerous new glacial lakes, which are the major cause of GLOFs.
On Earth, the albedo effect has a significant impact on our climate. The lower the albedo, the more radiation from the Sun that gets absorbed by the planet, and temperatures will rise. If the albedo is higher, and the Earth is more reflective, more of the radiation is returned to space, and the planet cools.
Increasing global climate leads to decrease albedo over ice surface thus causing melting of ice and formation of Glacial Lakes. Glacier lakes can be hazardous; moraine and ice dams can fail, causing catastrophic glacier lake outburst floods or jokulhlaups.
