Climate change has hastened glacial melting across the Hindu Kush Himalaya region, home to some of the world's tallest peaks, including Mount Everest. It looks just like what we would expect if warming were the dominant driver of ice loss,he said. Results indicate between 34 and 90% of water comes from melt during the dry, pre-monsoon season, with an average meltwater contribution of 65%. As the glaciers melt unconventionally, it will eventually result in water shortages. Do you know glaciers are large bodies of ice that can be formed high in the mountains? As global warming increases, glaciers melt faster and faster from the bottom, reducing their mass. This is because meltwater from the glaciers in the region feeds major rivers that support India's vast .

But in the mountainous Karakoram region of Asia home to K2, the second-highest peak on Earth the glaciers . In fact, the IPCC mentions them in their section on glaciers - including a Himalayan glacier in the Karakoram mountains. NIH has been conducting several studies for the assessment of runoff from melting of glaciers at catchment and basin scales across Himalaya. The problem will be induced by soil saturation and slope failure as the ground is exposed. It also shortens the glacier. There will be volumes of water released onto slopes which before had been protected by solid sheets of ice. This is the clearest picture yet of how fast Himalayan glaciers are melting over this time interval, and why, said lead author Joshua Maurer, a Ph.D. candidate at Columbia Universitys Lamont-Doherty Earth Observatory. New Zealands quest to become a dark sky nation. Human activity is the main culprit in the emission of carbon dioxide and other greenhouse gases.

Researchers calculated the amount of melting likely to result from warmer temperatures to confirm that one degree was indeed enough to produce such a massive loss of glacier ice. Glaciers there started wasting shortly after that increase, and rapid loss of ice has continued since then. Another factor: Asian nations are burning ever-greater loads of fossil fuels and biomass, sending soot into the sky. The time shift started as a way to maximize limited daylight hours, but its benefits are debatable. The Himalayan glaciers are retreating at rates ranging from 10 to 60 metres per year, and many small glaciers (< 0.2 sq km) have already disappeared. The melting of the glaciers, a phenomenon that intensified in the 20th century, is leaving our planet iceless. University of Leeds. There is scientific consensus that human-caused climate change has resulted in accelerated ice melt from glaciers and higher ocean temperatures across the world. Response: Some glaciers are growing. The research, published Monday in the journal Scientific Reports, found that massice loss from nearly 15,000 ice sheets in the Himalayas is especially rapid compared with other parts of the world.

WIHG is monitoring a few glaciers in Uttarakhand, which reveal that the Dokriani Glacier in the Bhagirathi basin is retreating at 15-20 m/a since 1995, whereas Chorabari Glacier in the Mandakini basin is retreating at 9-11 m/a during 2003-2017. Its also threatening water supplies for hundreds of millions of people downstream across much of Asia. Global warming is on track to transform the frigid, glacier-covered mountain peaks[into] bare rocks in a little less than a century, said Philippus Wester of the International Center for Integrated Mountain Development in a statement. The Hindu Kush Himalayas are the freshwater towers of South Asia and parts of Southeast Asia. Shifts in the South Asian monsoon might also have played a role in the ice loss in the Himalayas, researchers said. (917) 370-1407 Those were then compared to more recent sophisticated NASA satellite imagery that shows changing elevations of the ice over time. Himalayan glaciers are melting at an 'exceptional rate' Almost half the glacial ice in the world's tallest mountain range will soon have disappeared compared to just a few centuries ago. The rapid ice melt threatens agriculture and water supplyfor millions of people in South Asia, according to research published Monday in the journal Scientific Reports. Melting of Himalayan glaciers has doubled since the start of the 21st century due to rising temperatures, losing over a vertical foot and half of ice each year and potentially threatening water . The. The researchers created an automated system to turn these into 3D models that could show the changing elevations of glaciers over time. Meltwater contribution was estimated from 18 O isotopic data using a two-component mixing model with the Khumbu glacial melt and pre-monsoon rain as endmembers. Debris-covered glaciers in the south contributed 46.5% of total mass loss, despite making up only 7.5% of all Himalayan glaciers, meaning that their total mass loss is majorly disproportionate to . The analysis, spanning 40 years of satellite observations across India, China, Nepal and Bhutan, indicates that glaciers have been losing the equivalent of more than a vertical foot and half of ice each year since 2000 double . Researchers found that the Himalayanglaciers have lost about 40%of their area in the last several hundred years, or an estimated 390 to 586 cubic kilometers of ice enough to raise global sea levels 0.92 to 1.38 millimeters. The signal showing Himalayan ice loss linked to rising temperatures would not be so clear if it werent for the U.S. spy satellitesKH-9 Hexagon military satellites from 1973 to 1980 to be precisethat photographed the region. Changri Nup Glacier, one of the hundreds studied by the researchers. A one degree C increase is a huge change, says co-author Joerg Schaefer, a professor at Columbia Universitys Lamont-Doherty Earth Observatory. The study does not include the huge adjoining ranges of high-mountain Asia such as the Pamir, Hindu Kush or Tian Shan, but other studies suggest similar melting is underway there as well. Following a more pronounced warming trend starting in the 1990s,starting in 2000 the loss accelerated toabouthalf a meter (20 inches)annually. Reasons behind fast melting of glaciers: Divecha Centre for Climate Change, IISc Bangalore under the aegis of DST has investigated Satluj River basin and reported that there will be an increase in glacier melt contribution until the middle of the century and then there will be a decline. The study shows that even glaciers in the highest mountains of the world are responding to global air temperature increases driven by the combustion of fossil fuels, said Joseph Shea, a glacial geographer at the University of Northern British Columbia who was not involved in the study.
