Sikkim’s glaciers melting faster than other Himalayan regions: Study 

Last updated on March 26, 2020

Sikkim’s glaciers are dropping mass faster than other components of the Himalayas, as per a examine of Geology of the Himalaya. The examine was carried out by scientists from the Wadia Institute of Himalayan Geology, an autonomous analysis institute in Dehradun. 

The examine found that the glaciers in Sikkim are melting at a better magnitude than other Himalayan areas. The examine was revealed within the worldwide scientific journal, Science of the Total Environment.

 The examine assessed the response of 23 glaciers of Sikkim to local weather change between 1991 and 2015 and revealed that the glaciers have retreated and deglaciated considerably throughout the interval. 

Study: Key Findings

• While the small-sized glaciers in Sikkim have been lowering, the bigger ones are thinning on account of local weather change. 

• The magnitude of dimensional adjustments and particles development has been reported to be increased within the Sikkim, compared to other Himalayan areas. 
• The examine noticed a significant shift within the behaviour of glaciers round 2000. While the glaciers in western and central Himalayas had been reported to have slowed down in latest a long time, the glaciers in Sikkim confirmed negligible deceleration after 2000. 

• The rise in summer season temperature has been regarded as the primary cause behind the adjustments in glaciers. 

• Sikkim’s glaciers have usually not been studied intimately, therefore to grasp them higher, the scientists carried out an in depth literature survey to evaluate the present information concerning the numerous parameters of Sikkims’s glaciers together with their size, space, snow-line altitude, particles cowl and the way they reply to world warming. 

• Then the scientists chosen 23 consultant glaciers from the area based mostly on numerous components together with size, dimension, particles cowl, slope and other particulars. 

• They then procured the multi-temporal and multi-sensor satellite tv for pc information overlaying the chosen glaciers. 

• The group analysed the outcomes and in contrast it to the present research and the influence of assorted components was systematically explored. 

Sikkim’s Glaciers: Behavioural change

The behaviour of the glaciers in Sikkim has largely been heterogeneous and largely decided by their dimension, particles cowl and glacial lakes. Though melting is noticed in each small and large-sized glaciers, they appear to undertake totally different strategies to deal with local weather change. The smaller glaciers are identified to largely deglaciate to regulate to the change, the massive glaciers lose mass via thinning. 


Accurate information of the magnitude of glacier adjustments can create consciousness amongst widespread individuals, particularly these dwelling close by concerning potential glacier hazards and water provides. The examine may also present baseline information on glacier adjustments and discover the varied influencing components. A deeper understanding of the glacier state will assist form future research in addition to allow taking vital measures.  



There has not been a lot examine on the glaciers in Sikkim and most field-based measurements of mass stability have been carried out on just one glacier- ChangmeKhangpu and that too between 1980-1987. Hence, the newest examine for the primary time studied totally different parameters of Sikkim’s glaciers and explored their behaviour.
