The Tibetan plateau and the Himalaya-Hindu Kush mountain range are part of what is known as the world's Third Pole because the huge ice fields contain the largest reserve of fresh water outside the polar regions. Glaciers in China's bleak Qilian mountains high on the Tibetan plateau are disappearing at an alarming rate. Such outbursts may take place when glacial lakes caused by melting glaciers form behind moraines and ice dams. Things start going wrong when the water that is melting is more than the snow that is replacing it. Glaciers in China’s Qilian mountains are melting at an accelerating pace, threatening regional water supplies in the years ahead, according to Reuters. PMD official urges for investment in more stations to monitor the rate of melting. This teaching module not only looks into the problem of glacial melting, but also at the still largely unknown consequences of this development, such as glacial lake outburst floods. copyrighted © 2020 The Express Tribune. Using two case studies, the pupils examine more closely the impacts on and options for action open to an industrialised country (Switzerland) and a developing country (Nepal).

The UN climate panel said in a landmark 2019 report the high mountain glaciers in the Hindu Kush Himalaya region, which provide water for about two billion people, are melting quickly and this could accelerate unless mankind makes deep cuts in greenhouse gas emissions. Meltwater feeding the rivers would then decline as the glaciers shrink. Rapid melting of ice sheets in West Antarctica is already speeding up glaciers there, while scientists say Greenland is starting to melt faster than at any time in the past 12,000 years. Effects Of Glaciers Melting Climate change triggered melting of glaciers threatens the survival of many species including humans.

GILGIT: Melting glacier ice owing to hot weather conditions in Gilgit Baltistan has increased the risk of flash floods setting alarm bells ringing for locals. Just as concerning is the overall loss of mass, or thickness. Rapid melting of glaciers has resulted in the formation and expansion of moraine-dammed lakes, creating a potential danger from glacial lake outburst floods (GLOFs). He announced to launch a Glacial Lake Outburst Flood (GLOF) Safety project at the earliest to reduce the risks of flash floods. Climate change fuels sharp increase in glacier lakes, Massive chunk of Greenland's largest glacier bigger than Paris crashes into sea, Australia forecasts prolonged wildfire seasons, more droughts from climate change, Global warming to continue no matter what we do, study shows.

(Photo credit: Eric Gaidos) Which are the causes of the melting of the glaciers?First of all, it is important to know that the causes are not natural. Temperatures rise in future: This region is the source of 10 major river systems, including the Brahmaputra, Ganges, Indus and Mekong, which are economic engines of the region. As glacier ice melts, it can collect in large glacial lakes, which are at risk of bursting their banks and creating deadly flash floods downstream in places like Hassanabad. This article is now fully available for you, Please verify your e-mail to read this subscriber-only article in full. For more information, please see our Comments FAQ. The melting of glaciers was triggering more frequent “glacial lake outburst floods,” when masses of melted water burst through brittle rock barriers and inundating valleys below, said the report. Scientists have long studied the development of these floods, which are some of the largest on Earth. Since the 1950s, the largest glacier, known as Laohugou No. Of even greater concern are the glaciers in Greenland and Antarctica, which could push up sea levels by many metres in the coming centuries if the world stays on track to warm at least 3 deg C by the end of this century. The main cause of such warming is thought to be the ‘greenhouse effect’ that is majorly in effect due to humans. Save The World: ‘Global warming triggering to floods’. Accelerated melting increases river flows and heightens the risks of floods. Meltwater from shrinking glaciers is creating vast lakes that could eventually pose an enormous flooding threat, says newly published research. The melting in the mountains could peak within a decade, after which snow melt would sharply decrease due to the smaller, fewer glaciers, China Academy of … The danger is that rapid melting will, initially, increase water flows in the next few decades. The largest glacier in the 800km mountain chain on the arid north-eastern edge of the plateau has retreated about 450m the 1950s, when researchers set up China's first monitoring station to study it. glaciers are retreating at a startling rate in the Himalayas and the major causal factor has been identified as climate change (Ageta and Kadota, 1992; Yamada et al., 1996; Fushinmi, 2000). Mer de Glace, the longest glacier in France, has receded more than 2km up the mountain since the 19th century, with the pace of melting picking up in recent decades. The ejected section covered about 110 sq km, or about a seventh the size of Singapore. Now, their relationship is unraveling as pollution and global warming cause the Ultar glacier to melt and form unstable lakes that could burst their icy banks at any moment.

Environment Melting Himalayan glaciers herald floods and droughts for region Millions of Asians depend on the great rivers that flow from the Himalayas for their water supply. Switzerland has lost more than 500 glaciers since 1900. Glacial melt will affect freshwater flows with dramatic adverse effects on biodiversity, and All rights reserved. Billions of people, especially in Asia, rely on these vast storehouses of ice for drinking water, irrigation and hydropower.

The melting of the glaciers is due to men’s behavior.We have seen the first effect starting from the XX century. While current melting trends can’t be slowed or reversed, the information collected through the GLIMS project will enable researchers to better understand the relationship between climate and glaciers, and to better predict areas of Experts believe that the fast melting of glaciers combined with the heavy monsoon rains caused last year’s massive floods that affected around 20 million people and destroyed 1.6 million homes. While the rate of melting was slower this year, a big chunk of ice broke away from the Arctic's largest remaining ice shelf - 79N, or Nioghalvfjerdsfjorden - in north-east Greenland in June and July. According to a New Scientist report in 2019, visitors exiting a nearby train station could descend down three steps to reach the glacier in 1988. 12 glacier in … Global warming is speeding up melting and disrupting weather patterns that can bring too much or too little rain to the mountains. But it is not just the distance that glaciers are retreating. In one example, glaciers in China's bleak Qilian mountains high on the Tibetan plateau are disappearing at an alarming rate, raising the prospect of crippling, long-term water shortages, scientists say. Accelerated melting increases river flows and heightens the risks of floods. A marker indicating the level of the Mer de Glace glacier in 1990 is seen in Chamonix on June 17, 2019. Rapid melting of glaciers from China to Greenland and Antarctica also increases sea levels, threatening low-lying coastlines globally.
