The Himalayan Mountains are home to the highest peak in Mount Everest at 29,029 feet, but also to the third largest deposit of ice and snow in the world, after Antarctica and the Arctic. A climate researcher at Kathmandu University, Chand is carrying out vital field work, looking at high mountain glaciers as indicators of climate change. Recently-deglaciated terrains have been a subject of ecological studies for a long time, as they represent a unique natural model system for examining the effects of global warming associated with glacier retreat on biodiversity and the spatio-temporal dynamic of communities. The glacier is now retreating at an average rate of 6.7 plus/minus 3 metre per annum. Because the success of our exhibit in Beijing last fall, the Ministry of Environment and Forests in India wants to display these exhibits in the countrys mountainous states. In the last of his reports from the region he describes the difficulties of establishing why so many of Nepal's glaciers appear to be shrinking. By 2050, this figure is expected to increase to 25-35%. The melting of glaciers in the Himalayas is a major cause of concern as it will have a massive impact on the water supply for rivers.

"And the problem is that moraine dam is unstable. 15 . Phenomena associated with retreating glaciers threaten regional water security. 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.

Quoting media reports, the committee said due to glacial retreat, the Himalayan region has lost 13 per cent of its glaciers in the last four decades resulting in the loss of 443 billion tonnes (Gt) glacial ice. While initially the retreating glaciers will not have a direct impact on water flow in rivers, except in the Indus where 26 per cent flow is from glacier melt, this is likely to change soon, says the study. Such policy decisions may include estimating climate impacts on agriculture, water resources, electricity and power generation, and human and environmental health. The Hindu Kush Himalayas (HKH) are a 3,500-square-kilometer stretch of mountains that span eight countries. Climate Centrals Program on Sea Level Rise strives to provide accurate, clear and granular information about sea level rise and coastal flood hazards both locally and globally, today and tomorrow. "These high-resolution, precise images allow us to understand the changes in mass across a half-century or even a whole century.. They hear a lot of people talking about climate change, but its a slogan save the Himalaya and people dont really sit down to ask whats happening. Additional water or pressure, or structural weakness, can cause both natural and man-made dams . The data collected might be about you, your device, your preferences, or your login information. Many Intergovernmental Panel on Climate Change (IPCC) reports give a global perspective, but not many details are available on regional changes, including those for India, said MOES Secretary Madhavan Rajeevan. To a lot of scientists, since were not collecting pure data, this isnt something they recognize. The rate glaciers are melting in the Himalaya is being significantly accelerated by lakes already formed by glacial retreat, new research led by the University of St Andrews has found. Tom Painter, a research scientist at JPL who studies the effect of dust on snow pack and snow melt around the world, said Breashears' work is making an important contribution to science. Cookies the University sets are called first-party Cookies. However, the study forecasts that in all three basins, there would be a decrease in snow and a rise in glacier melt by the middle of the century. Everybodys creating awareness. Meanwhile, in the Himalayas, annual glacier runoff is forecast to jump around 2050, before it plunges steadily afterward.If countries fail to keep global warming under 1.5 degrees, or even 2 . In the Himalaya, we still have a horribly difficult time achieving the measurements we need to understand glacier retreat and the contributions to sea level rise," Painter said. Carbon Deposits on Gangotri. Observations show indications of significant warming in the region, causing the Himalayan glaciers to retreat. The region is called the Third Pole, as it contains the largest reserve of freshwater outside the polar regions.

Receding glaciers would also have an impact on the rates of . Dark debris cover, for example, absorbs solar radiation rather than deflecting it and therefore often increases a glaciers rate of retreat. But the cultural barrier to change may be too high for local people to adopt them. Thats a very personal journey for everyone. The retreat means countries like Nepal and Bangladesh, which rely on these mountain water cycles, will have to adapt. Most of the black carbon falling on the Himalayas and the south of the Tibetan plateau comes from the plains of India, while that of the eastern and northern sections of the plateau comes mainly from China.According to recent ICIMOD estimates, black carbon is probably responsible for a large part - around 30 percent by some calculations - of glacial retreat in the region.ICIMOD and other bodies admit there is far too little field data available to draw solid conclusions, whether on overall glacial melt or on the influence of black carbon. The retreat of glaciers since 1850 affects the availability of fresh water for irrigation and domestic use, mountain recreation, animals and plants that depend on glacier-melt, and, in the longer term, the level of the oceans.Deglaciation occurs naturally at the end of ice ages, but glaciologists find the current glacier retreat is accelerated by the measured increase of atmospheric greenhouse .
