The greater Himalayas hold the largest mass of ice outside Polar Regions and are the source of the ten largest rivers in Asia. Rapid reduction in the volume of Himalayan glaciers due to climate change is occurring, (Wilkes & Eriksson, 2009). With a highly heterogeneous geography, the region has a great climatic variability and forms a barrier to atmospheric circulation for the summer monsoon and winter westerlies. The regions climatic zones contain a rich diversity of species and ecosystems that exist along a pronounced humidity gradient, (Wilkes & Eriksson, 2009). Vegetation changes from subtropical semi desert and thorn steppe formation in the northwest to tropical evergreen rainforests in the southeastern Himalayas, (Wilkes & Eriksson, 2009). Climate change impacts are already occurring in the Greater Himalayas, the most widely reported effect is the rapid reduction of glaciers, which has implications of future downstream water supplies, (Wilkes & Eriksson, 2009). The Himalayas as a whole are very sensitive to global climate change. Progressive increases in warming at high elevations are occurring at approximately three times the global average, (Wilkes & Eriksson, 2009). The intergovernmental Panel on Climate Change has projected that average annual mean warming will be about three degrees warmer by 2050 and about five degrees warmer in 2080 over the Asian land mass, (Wilkes & Eriksson, 2009). Given that current discussions about dangerous climate change are
