The polluted air visible as smog and piles of trash polluting the Bagmati in Kathmandu, 2023. Environmental issues in Nepal include a number of issues, such as deforestation, climate change, energy and species conservation. Many of these issues have been precipitated by rapid industrialization without major environmental regulation. [1]
Altogether 14 glacial lake outburst floods (GLOFs) [19] occurred between 1935 and 1991. In total, 21 GLOFs [20] have been identified as being potentially dangerous at present. In this way, CC and livelihoods integral part and have vice versa relationship. The low income and subsistence users are about 38% of total population.
Examples include mountain glaciers in western North America, Asia, the Alps in central Europe, and tropical and subtropical regions of South America and Africa. Since glacial mass is affected by long-term climatic changes, e.g. precipitation, mean temperature, and cloud cover, glacial mass changes are one of the most sensitive indicators of ...
As glaciers melt and pour massive amounts of water into nearby lakes, 15 million people across the globe live under the threat of a sudden and deadly outburst flood, a new study finds. More than ...
In this Hubbard Glacier image from 16 July 2002, the glacier has closed off Russell Fjord from Disenchantment Bay. The waters behind the glacier rose 61 feet (19 m) in 10 weeks, creating a short lived Russell Lake. A glacial lake outburst flood is a type of outburst flood occurring when water dammed by a glacier or a moraine is released.

An east-facing view of the confluence of Imja Tsho and the Imja Glacier. The lake was first mapped in the form of a few ponds from a satellite image taken in 1962. The total area of the ponds was approximately 0.03 km 2 then (27916 sq m). With the melting of glaciers, the ponds merged into a supra-glacial lake in the 1970s and it has grown ...
In geomorphology, an outburst flood—a type of megaflood—is a high-magnitude, low-frequency catastrophic flood involving the sudden release of a large quantity of water. [1] [2] During the last deglaciation, numerous glacial lake outburst floods were caused by the collapse of either ice sheets or glaciers that formed the dams of proglacial ...
