For billions of people, mountain meltwater is essential for drinking water and sanitation, food and energy security, and the integrity of the environment. But today, as the world warms, glaciers are melting faster than ever, making the water cycle more unpredictable and extreme. And because of glacial retreat, floods, droughts, …
In this study, we apply a glacier mass balance and ice redistribution model to examine the sensitivity of glaciers in the Everest region of Nepal to climate change. High resolution temperature and precipitation fields derived from gridded station data, and bias-corrected with independent station observations, are used to drive the …
The Karakoram and the Himalayan mountain range accommodate a large number of glaciers and are the major source of several perennial rivers downstream. To interactively describe to response of glaciers to climate change, a glacier parameterization scheme has been developed and implemented into the regional climate model REMO. The scheme …
A traffic sign is seen near Barrick Gold Corp.'s Veladero gold mine, on the Argentine side of the border district between Chile's Huasco province and Argentina's San Juan province, a few kilometers from the site for the Pascua Lama gold project Chile's Environmental Court ruled on Monday that Barrick Gold …
Glaciers in the eastern Himalayas are retreating, but this is not likely to affect river flows significantly in the coming decades, say scientists from the Kathmandu-based International Centre for Integrated Mountain Development (ICIMOD). An ICIMOD report presents fresh evidence of retreating glaciers in the eastern Himalayas in India and Nepal. …
The behavior of marine-terminating ice sheets, such as the West Antarctic ice sheet, is of interest due to the possibility of rapid grounding-line retreat and consequent catastrophic loss of ice. Critical to modeling this behavior is a choice of basal rheology, where the most popular approach is to relate the …
We analyzed volume change and mass balance of outlet glaciers of the northern Antarctic Peninsula over the period 2011 to 2013, using topographic data of high vertical accuracy and great spatial detail, acquired by bistatic radar interferometry of the TanDEM-X/TerraSAR-X satellite formation. The study area includes glaciers draining into the …
Order of the National Green Tribunal in the matter of Court on its own Motion Vs. State of HP &Ors.; relating to one of the most eco-sensitive area of the Himachal Pradesh i.e. Rohtang Pass.
Climate change has shrunk Peruvian glaciers by 40 percent in the past four decades and the melt-off has spawned nearly 1,000 new high-altitude lakes since 1980, Peru's government said on Wednesday. Nearly 90 percent of Peruvian glaciers are smaller than 1-square-kilometer, putting them at greater risk of disappearing in coming …
The northern Antarctic Peninsula is currently undergoing rapid atmospheric warming. Increased glacier-surface melt during the twentieth century has contributed to ice-shelf collapse and the widespread acceleration, thinning and recession of glaciers. Therefore, glaciers peripheral to the Antarctic Ice Sheet currently make a large contribution to eustatic sea-level rise, but future …
Managing water resources is one of the major challenges of our century. Nowhere could this be more so than for the waters emanating from the Hindu Kush Himalayas, which is already characterized by a situation of ‘too much and too little’ water. Floods and droughts are already common, and the …
An attempt has been made to characterize the subglacial pathways that transport the meltwaters from Chaturangi and Raktavarn glaciers through the lower ablation zone of the Gangotri glacier, Indian Himalaya, by means of dye tracer experiments. Original Source
This study focuses on the present-day surface elevation of the Greenland and Antarctic ice sheets. Based on 3 years of CryoSat-2 data acquisition we derived new elevation models (DEMs) as well as elevation change maps and volume change estimates for both ice sheets. Here we present the new DEMs and …
The Purog Kangri glacier is the third largest glacier in the world and research shows that global warming is exerting its negative influence The Tibetan plateau, whose glaciers supply water to hundreds of millions of people in Asia, were warmer over the past 50 years than at any stage in …
The new research has found that New Zealand is slowly losing its glaciers and could lead to severe decline in the coming years. The country's National Institute of Water and Atmospheric Research (NIWA) conducted and studied aerial surveys before arriving at this conclusion. Researchers from the University of Auckland and …
New Zealand’s vast Southern Alps mountain range has lost a third of its permanent snow and ice over the past four decades, diminishing some of the country’s most spectacular glaciers, new research has found. A study of aerial surveys conducted by the National Institute of Water and Atmospheric Research (Niwa) …
Uttarakhand has 76 dams in the ecologically fragile regions. The Chopra Committee, which studied the impact of receding glaciers on hydroelectric power projects (HEPs), has in its report objected to the construction of HEPs in regions between 2,200 to 2,500 metres above the sea level (paraglacial regions). Uttarakhand has 76 …
The Himalayan region contains some of the most dynamic, fragile and complex mountain ranges in the world. These magnificent mountain ranges play an important role in global atmospheric circulation, the hydrological cycle, and water resources availability, provide a wide range of ecosystem services, and are a source of many hazards. …
Despite retreating glaciers, the amount of water supplied by the Himalayan Mountains will increase in the coming decades, a study from FutureWater, Utrecht University and the International Centre for Integrated Mountain Development (ICIMOD) suggests. Glacier- and snowmelt contribute water to ten important river basins originating from the Himalayas and in …
Media storms attacking the science of climate change have only a fleeting effect on the public's interest and do not appear to alter opinions, according to new research. Oxford University scientists used the Google Trends tool to track web searches related to global warming over the past decade but found …
KATHMANDU: The second international conference on ‘Cryosphere of the Hindu Kush Himalayas: State of Knowledge’ organised by International Centre for Integrated Mountain Development with the support of the Royal Norwegian Embassy and the Embassy of the United States in Kathmandu has launched a publication titled Status and Decadal Glacier Change …
