NEPAL Rolwaling Glacier -- 16 Apr 2005 -- Glacial deposits high up in the Rolwaling Valley, which is remarkable as it is one of 13 known areas with a severe risk of 'glacial overbust' (when water coming from glacier melts builds up in a natural lake and threatens many kilometers of river valleys, mainly along the course of the Rolwaling River - pictured here - and the Tamakhosi River further west, etc.). Scientists have warned that rising temperatures from global warming may cause the demise of these Himalayan ice falls and glaciers. The effects of this are likely to affect many Asian nations, as these glaciers - and those in neighbouring Tibet - feed most of the large river systems from Pakistan to China. Widespread flooding has began and is expected to continue. In the 2004 Monsoon, some 30 million people in Nepal, India and Bangladesh were affected by serious flooding. Scientists add that after the glaciers have melted, their departure will lead to widespread drought across many areas of Asia
