'Meltwater' is the water released by the
melting of
snow or
ice, including
glacial ice. Meltwater provides
drinking water for a large proportion of the world's population, as well as providing water for
irrigation and
hydroelectric plants. It can also destabilize glacial lakes leading to sudden
floods, and destabilize
snowpack causing
avalanches.
[1] Meltwater also acts as a
lubricant in the
basal sliding of glaciers.
In a report published in June 2007, the
United Nations Environment Programme estimated that
global warming could lead to 40% of the
world population being affected by the loss of glaciers, snow and the associated meltwater in
Asia.
