Heavy rain, snowmelt, breaching of lake devastated Kedarnath 5.1.2018 General News
The combined effect of heavy rainfall, snowmelt and breaching of the Chaurabari lake could have resulted in an water outflow with large amount of debris which devastated the Kedarnath valley, the Lok Sabha was told today. Minister of State for Environment Mahesh Sharma, in a his reply to a question, said the devastation in the Kedarnath area is not mainly due to the glacier melt. "The devastation in the Kedarnath area is not mainly due to the glacier melt. The combined effect of very heavy rainfall, heavy snowmelt and breaching of the Chaurabari lake in the upstream could have resulted in a gushing outflow with large amounts of debris which devastated the entire valley," he said. Sharma pointed out that very heavy rainfall in the entire catchment area further increased the magnitude of floods. Uttarakhand had witnessed massive devastation in the June 2013 flash floods. To a question whether natural sources of water, such as lakes, waterfalls and glaciers are shrinking ...

The year in science 28.12.2017 Deccan Herald - Supplements
The year 2017 saw some tremendous breakthroughs in science. From genetic engineering, to quantum computing, to anthropology and climate science, some discoveries have left us in awe, and some have indeed pronounced a word of caution. As we draw down the curtains on this magnificent year, here is a snapshot on some of the remarkable contributions to science, in no particular order. Scientists create the first ever stable compound from helium Chemistry tells us that helium, the most abundant element in the universe, does not react with any other elements or compounds. Hence the name noble or inert gas. In a study published in the journal Nature Chemistry, researchers have proved this false. They have discovered the first ever stable compound from helium with sodium, at very high pressures. With a chemical formula of Na2He, the compound is surprisingly not formed by chemical bonds. Here, electrons fill up the voids in the sodium cubes, holding the compound together and making it an insulator. This ...

NASA study reveals how lakes and riviers survive under Antarctica's Marie Byrd Land 8.11.2017 DNA: Money
A geothermal heat source called mantle plume lies deep below Antarctica's Marie Byrd Land, explaining some of the melting that creates lakes and rivers under the ice sheet, a NASA study has found. Although the heat source is not a new or increasing threat to the West Antarctic ice sheet, it may help explain why the ice sheet collapsed rapidly in an earlier era of abrupt climate change, and why it is so unstable today. The stability of an ice sheet is closely related to how much water lubricates it from below, allowing glaciers to slide more easily, NASA said. Understanding the sources and future of the meltwater under West Antarctica is important for estimating the rate at which ice may be lost to the ocean in the future. Antarctica's bedrock is laced with rivers and lakes, the largest of which is the size of Lake Erie. Many lakes fill and drain rapidly, forcing the ice surface thousands of feet above them to rise and fall by as much as six metres. The motion allows scientists to estimate where and how ...

Climate change has enormous implications in Himalayas: Senator 2.11.2017 deccanherald.com
Climate change has "enormous" geopolitical implications in the Himalayas, particularly in the region between India and Pakistan, where destabilisation of water flows make the area ripe not just for conflict but also for devastation, a top US Senator has warned. Noting that Pakistans major rivers are all fed by glacial meltwater from India, Senator Sheldon Whitehouse told a Washington audience this week that more melting meant more flow, and climate change also can intensify heavy rains during the monsoon season. Referring to a study, he said even an optimistic scenario on climate change would cut the Himalayan glacier mass more than a third by 2100. Business as usual means loss of nearly 70% of glacier mass, Whitehouse said, adding that "because they are melting, the glaciers are also shrinking". "This has enormous geopolitical implications," he said in his key note address to The Hudson Institute, a top US think-tank, on the release of a report "An Integrated Approach to the Himalayas". "In the region, ...
