NEPAL Pheriche -- 16 Apr 2005 -- Sherpas return to the small village of Pheriche in the Khumbu Valley with their Yaks. 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, though widespread flooding is expected soon. 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. This could have serious implications for agriculture across the region
