NASA tool predicts which cities will flood due to melting ice 16.11.2017 Hindu: Science
NASA has developed a new forecasting tool that can predict which cities will be affected as different portions of ice sheets melt due to global warming. The tool looks at the Earth’s spin and gravita...

Heat source under Antarctica responsible for melting ice sheet: NASA 8.11.2017 Zee News : Science and Technology
The stability of an ice sheet is closely related to how much water lubricates it from below, allowing glaciers to slide more easily.

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 ...

Carbon emissions put Pakistan's glaciers in danger 5.11.2017 New Kerala: World News
Islamabad [Pakistan], November 5 : Increase in the carbon emissions and the soot from various vehicles that pass through Khunjerab Pass in the Karakoram Mountain range will lead to melting glaciers in Pakistan, experts have warned.

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, ...

Impacts of glacier mass loss 20.9.2017 Deccan Herald - Tuesday
RAPID SHRINKAGE Researchers have warned of an urgent worldwide need to address a broad spectrum of cascading impacts of glacier mass loss on downstream systems. In their paper, published in Proceedings of the National Academy of Sciences, the authors synthesised currently available evidence and documented the profound impact on freshwater and near-shore marine systems. Glaciers cover close to 10% of the Earth's land surface but are shrinking rapidly across most parts of the world. Glacier shrinkage will alter sediment transport, and biogeochemical and contaminant fluxes from rivers to oceans. An unexpected impact of glacier shrinkage is the liberation of contaminants including emission products from industrial activity such as black carbon and associated compounds, mercury, pesticides, and other persistent organic pollutants. Though there is uncertainty in the release of these legacy contaminants from glacierised areas, their transport to downstream systems by meltwater will eventually reduce as glacial ...

Global warming scare: Glaciers in Asia to shrink by 33% by 2100 14.9.2017 DNA: Mumbai
Asian glaciers are set to shrink by at least a third by 2100 due to climate change, researchers said on Thursday, threatening millions who depend on their meltwaters for drinking, farming and hydro-electricity. The scientists' prediction is based on an assumption the world will limit global temperature rises to 1.5 degrees Celsius above pre-industrial levels - although many expect Earth will be much hotter than this by the end of the century. "As we have already considerably warmed the earth since the industrial era, we have caused an imbalance of the glaciers," said Philip Kraaijenbrink, the study's author and a geography researcher at Utrecht University in the Netherlands. "We observe their retreat almost everywhere on the globe. Even if we (do) not warm the climate any more at all, starting today, 14 percent of the ice will be lost," he told the Thomson Reuters Foundation. Under the Paris climate accord, countries pledged to keep the rise in average global temperatures below 2 degrees Celsius above ...
