In 1988 we mapped four glaciers arrayed around the Kololo Peaks just south of Glacier Peak; Honeycomb and White River feeding into Wenatchee Lake watershed, while Whitechuck and Suiatlle fed into the Suiattle River watershed. Even under the most conservative Intergovernmental Panel on Climate Change (IPCC) RCP2.6 scenario (which explores the possibility of keeping average global temperature increase below 2C) a 1.5C increase of global temperatures will cause 2.1C of . This is alarming because the populations that live in the upper and middle Himalayas, in villages and even towns, are dependent on spring water. But the time frame to analyze glaciers response to climate change is too short to arrive at definite conclusions, Schaefer said, adding that it is difficult to rescue a glacier that has shrunk in size, as the main driver for glacier shrinkage is rising temperature.

A 2003 digital survey of 103 debris-free glaciers (small, and of similar length) from 1963 to 1993 determined that 90 were retreating, 13 were stationary, and none was advancing. Other impacts of this temperature change could include increased frequency of heat waves and more severe droughts, very severe cyclonic storms, and floods in Himalayan river basins. They had a combined area of 9.2 km. Umesh Haritashya, an associate professor of geology at the University of Dayton in Ohio, and his colleagues recently analyzed a small GLOF caused by a surge in the Shispare Glacier in Pakistan that damaged a major highway, for instance. A rigorous testing program is the best way to ensure that every part of the Surface Water and Ocean Topography mission, down to the ball bearings, will work smoothly in orbit. Such events wreak destruction on small settlements and other infrastructure such as dams and hydropower plants downstream. The Arctic is being affected by climate change more than most places on Earth. The study . "Multiple researchers presented evidence of the retreat of glaciers in the eastern Himalayas, but suggested that river flows will not decline significantly in the coming decades as melt rates and precipitation are projected to increase," the Kathmandu-based International Centre for Integrated Mountain Development (ICIMOD) said. Even so, it is clear, Rajeevan said, that India needs to reduce its greenhouse gas emissions and move on to renewable energy sources like wind, solar, and ocean waves, in addition to improving forest cover and other means to absorb the countrys carbon dioxide emissions.
