== Debris cover is not protecting Himalayan glaciers==

The glacier melt areas in the Himalayas are experiencing a significant loss of ice due to global warming, despite the presence of a blanketing layer of debris over half of the area, a new study found. The study , conducted by the Pune-based Indian Institute of Science Education and Research (IISER), focused on the observed rate of ice loss between the melt areas covered under debris and those without, and explained why the areas covered by thick layers of rock and debris are experiencing an equally significant loss of ice as their counterparts.

Such areas comprise 50% of the glacier melt areas in the mountain range, and will continue to lose more ice compared to the debrisfree areas in the long run, the IISER study warned.

According to lead researcher Argha Banerjee, assi stant professor (earth and climate science) at IISER, the typical high and steep valley walls surrounding Himalayan glaciers supply a lot of rock debris, leading to a layer of debris on the lower melt-zone that acts as an insulating blanket, reducing ice melt.

Banerjee told TOI that shrinking glaciers in the Himalayas have a profoundly negative effect on water security, including water needs for agriculture and hydropower generation, for people living in the Indus basin and in the upper reaches of the Ganga-Brahmaputra basin.

Glacial meltwater supply, Banerjee said, acts to sof ten the impact of drought in these areas.

“Glacier shrinkage exposes mountain people to increased risk from hazards like glacial lake outburst floods,“ he said.

The IISER study was recently published in the international journal, `The Cryosphere'.

 ==2000-2020: the extent of the melt under estimated by 6.5%==
 [https://epaper.timesgroup.com/article-share?article=05_04_2023_010_001_cap_TOI  Vaishnavi Chandrasekhar, April 5, 2023: ''The Times of India'']
 Glacial ice melt in the Himalayas between 2000 and 2020 may be underestimated by approximately 6. 5% , and as much as 10% in central Himalayas, as per a new study published in Nature Geoscience.
  Although the differences in mass loss estimations may not seem high, the finding is important because lake-terminating glaciers comprise about 25% glacier area in the Himalayas, said Tobias Bolch, study co-author and professor at Graz University of Technology in Austria.
@@ Line 73: / Line 75: @@
  The study looked at one particular kind of glacier: those that terminate in a lake or a body of water. Glacial lakes are growing in the Himalayas and other high mountain areas due to rising temperatures.
  For this study, a team of international scientists used satellite data and formulas to estimate the change in the volume of glacial lakes in the Himalayas for the period between 1990 and 2020 and thus quantify the mass loss happening under the lake as the submerged part of the ice turns into water. They then crosschecked their findings with fieldmeasurements of 16 glacial lakes.
@@ Line 78: / Line 81: @@
  Most of these “lake-terminating” glaciers are located in the central Himalayas, eastern Himalayas, and the Nyainqêntanglha mountains in Tibet. It is also in these areas where the underestimation of ice loss has been highest, the study found, as glacial lakes have grown.
