•unpredictable monsoon, leads to rise in food price &Social Instability.
•Rapid melting of glaciers, results in glacier lake outburst floods.
•Permafrost degradation and glacier retreat threaten the survival of great rivers of Asia.
•Increase of river volume in short term Resulting in floods but danger of rivers been dried up
