Spatially heterogeneous wastage of Himalayan glaciers.
We describe volumetric changes in three benchmark glaciers in the Nepal Himalayas on which observations have been made since the 1970s. Compared with the global mean of glacier mass balance, the Himalayan glaciers showed rapid wastage in the 1970s-1990s, but similar wastage in the last decade. In the last decade, a glacier in an arid climate showed negative but suppressed mass balance compared ...
متن کاملSpatially variable response of Himalayan glaciers to climate change affected by debris cover
Controversy about the current state and future evolution of Himalayan glaciers has been stirred up by erroneous statements in the fourth report by the Intergovernmental Panel on Climate Change1,2. Variable retreat rates3–6 and a paucity of glacial mass-balance data7,8 make it difficult to develop a coherent picture of regional climate-change impacts in the region. Here, we report remotely-sense...
متن کاملApplication of SAR Interferometry for Himalayan Glaciers
With the help of ERS 1 and 2 tandem data, we have produced DEM and glacier movement of two major Himalayan glaciers in India. The glaciers showed good correlation but the surrounding areas had more decorrelation. Contours generated with ERS 1 and 2 SAR tandem data are comparable with topographic maps. We have used SRTM DEM to study the glacier movement involving two-pass differential method. Th...
متن کاملThe state and fate of Himalayan glaciers.
Himalayan glaciers are a focus of public and scientific debate. Prevailing uncertainties are of major concern because some projections of their future have serious implications for water resources. Most Himalayan glaciers are losing mass at rates similar to glaciers elsewhere, except for emerging indications of stability or mass gain in the Karakoram. A poor understanding of the processes affec...
متن کاملSources of black carbon to the Himalayan–Tibetan Plateau glaciers
Combustion-derived black carbon (BC) aerosols accelerate glacier melting in the Himalayas and in Tibet (the Third Pole (TP)), thereby limiting the sustainable freshwater supplies for billions of people. However, the sources of BC reaching the TP remain uncertain, hindering both process understanding and efficient mitigation. Here we present the source-diagnostic Δ(14)C/δ(13)C compositions of BC...
