The shrinking of Lirung and Khyimjung Glaciers: Hazards and opportunities

November 26, 2017
These Glaciers are main sources of fresh water that benefits millions of people downstream. The average global temperature has risen more than expected in the past few decades. Many prefer to use the milder term 'climate change' instead of the harsher 'global warming' to describe this change in average global temperature. Glaciers in the region are retreating in the face of accelerated global warming,
The main cause of such warming is thought to be the 'greenhouse effect' that is majorly in effect due to humans. With an increase in temperature, glaciers are melting faster than the time taken for new ice layers to form. Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities. Meanwhile glaciers retreat lakes form behind newly exposed terminal moraine. Rapid accumulation of water in these lakes can lead to sudden breaching of the unstable 'dams' behind which they are formed. The resultant discharges of huge amounts of water and debris -known as a Glacial Lake Outburst Floods, often have catastrophic effects. That causes creating plethora of problems for human kind and endanger several species of animal living there, which will hamper the balance of ecosystem.
So before going worse, we need to deal with the central facts of rising temperatures and all the endless trouble that global warming will bring.
