In Himalaya Mountains,
A Mixed Picture of Glacial Melting
A new study says that glaciers in the Himalayas are reacting to climate change in different ways
, with glaciers in the eastern and central Himalayas retreating at accelerating rates, while glaciers in the
western Himalaya and Hindu Kush region are more stable and possibly even growing in places. According to a report by the National Research Council
, many of the glaciers of the Himalayan region are retreating at rates comparable to other parts of the world, but changes to glacial meltwater are not likely to make a significant difference in water availability at lower elevations, which rely more on monsoon rains and snowmelt. If the the current rate of glacial retreat continues, however, the report said that high-elevation areas of some river basins could see altered seasonal water flow. In addition, researchers say the melting of glaciers could affect regional water security during periods of drought or “similar climate extremes.” The Himalaya/Hindu Kush region is the source of several river systems — including the Indus, Ganges, and Brahmaputra — that supply drinking water and irrigation to 1.5 billion people.
