According to a 2011 study by the Kathmandu-based International Centre for Integrated Mountain Development (ICIMOD), there are an estimated 54,000 individual glaciers in the Hindu Kush-Himalayan region, an area of mountains stretching from Afghanistan in the west to Yunnan in southwest China in the east. A glacier grows wherever snow accumulates faster than it melts. This is the first study to include all the world's glaciers -- around 220,000 in total -- excluding the Greenland and Antarctic ice sheets. It has the biggest reserves of water in the form of ice and snow outside the polar regions, and is the source of 10 of the largest rivers in Asia. This could be a major cause for concern, said Haritashya. }, Also, in a tense region where transboundary cooperation is severely limited, studies that have been done often use differing methodologies.Advances in satellite technology have significantly increased the volume and quality of data gathering across the region. The report projected that even with the Indian governments commitment to mitigate greenhouse gases by 2030, the Indian Himalayas could warm by 2.64.6 by 2100. A climate researcher at Kathmandu University, Chand is carrying out vital field work, looking at high mountain glaciers as indicators of climate change.Credit: NASA. The area covered by glaciers was reduced by a total of 13.2 0.0022 km 2 over this period. In the near term, by 2030, glaciers in the Hindu Kush Himalayan region are expected to lose between 10-30% of their mass. Tech InDepth: How do Hybrid vehicles work? Text. 18 The observed annual retreat rate of 1.6%/a for the Naimona'Nyi glaciers significantly exceeds the 0.42%/a for the entire western Himalayas, 0.41%/a for the middle Himalayas, and 0.57%/a for the eastern Himalayas (1980-2010). Dark debris cover, for example, absorbs solar radiation rather than deflecting it and therefore often increases a glaciers rate of retreat. 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. Its glaciers feed 10 large Asian rivers, including the Ganges, Mekong, and Yangtze. David Breashears summited Mount Everest for the first time in 1983. Regional details on climate changes are needed to frame suitable policy decisions to estimate impacts on agriculture, water resources, power, and health. However, the assessment makes clear that despite the surety of glaciers in the Hindu Kush Mountains losing length since 1973, no studies have been done to examine area change in this region. Now an international research team led by ETH Zurich and the University of Toulouse has authored a comprehensive study on global glacier retreat, which was published online in Nature on April 28, 2021. These data points are too few and far apart to be useful to scientists, but we want to get viewers interested in science in general. Debris Cover: There is a significant influence of debris cover on the mass balance and retreat of the glacier's endpoint, especially in summer. the average rate of retreat of the glacier per year has been about 12 to 13 metres," said Dr . Wheeler and David Breashears, respectively. When calculating data about monsoon rains, for example, Indian scientists have reported that regional climate models might even contradict the global models used by the IPCC. Now the first complete study of this remote region reveals that its glaciers lost billions of tons of iceequivalent to more than a vertical foot and half of ice each yearfrom 2000 to 2016. Yao and his colleagues analyzed the lengths and surface areas of about 7,100 glaciers, and changes in the mass balance of 15 glaciers .

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. Water security in HKH is also threatened by increased demand associated with improved socioeconomic conditions in the downstream region. More aggressively curbing black carbon emissions can slow . It was a claim the IPCC later said should never have been published, but one that was eagerly seized on by climate skeptics in efforts to try to undermine the whole body of the Panel's work.Mohan and his team are investigating two glaciers - one at Rikhashambha in north-central Nepal at 6,000 meters, described as a valley glacier, and one at Yala to the east, on the border with Tibet at between 5,100 and 5,700 meters, described as a plateau-type glacier.In general plateau-type glaciers mostly found in Tibet - seem to be retreating faster than valley types, says Dr. Mohan. "user": [], 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. This is alarming because the populations that live in the upper and middle Himalayas, in villages and even towns, are dependent on spring water. Then we can start a conversation about glaciers, the Himalaya, hydrology, black carbon, the albedo effect, and so many other things. By Press Trust of India: Glaciers in the Hindu Kush Himalayan (HKH) region will keep shrinking and the snow cover will retreat to higher altitudes, the latest IPCC report said on Monday..
