Foto de stock - NEPAL Ngozumpa Glacier -- 16 Apr 2005 -- An aerial view of the main Ngozumpa (Gokyo) glacier. Mount Gyachung Kang is visible in the upper right 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 -- Picture © Jon Mitchell / Lightroom Photos.
