Glaciers, glacial lakes and glacial lake outburst floods in the Mount Everest region, Nepal [PDF]

Annals of Glaciology, 2009
AbstractRecent climate changes have had a significant impact on the high-mountain glacial environment. Rapid melting of glaciers has resulted in the formation and expansion of moraine-dammed lakes, creating a potential danger from glacial lake outburst floods (GLOFs). Most lakes have formed during the second half of the 20th century.

Everest's thinning glaciers: implications for tourism and mountaineering [PDF]

, 2018
Glacier mass loss in the Everest region of Nepal is accelerating in response to a warming climate, which is a trend observed across the central and eastern Himalaya.

Early Holocene jökulhlaup chronology and deglaciation dynamics in central Iceland

Boreas, EarlyView.
Glacial lake outburst floods (jökulhlaups) have occurred throughout the Quaternary in glaciated regions worldwide. Reconstructing flood chronology yields insight into deglaciation processes, environmental change and the role of extreme events in landscape evolution.

Hazard assessment of glacial lake outburst floods from Kyagar glacier, Karakoram mountains, China [PDF]

, 2014
Kyagar glacier is located in the Chinese Karakoram mountains. The glacier tongue entirely blocks the riverbed in the upper Shaksgam valley and impounds a glacial lake, which was the source of several violent and disastrous glacial lake outburst floods ...

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Evaluating the Scale and Potential of GLOF in the Bhutan Himalayas Using a Satellite-Based Integral Glacier–Glacial Lake Inventory

Geosciences, 2017
A comprehensive glacier–glacial lake inventory was developed for the Bhutan Himalayas based on satellite observations between 1987–1990 and 2006–2011. In total, 733 lakes (covering 82.6 km2) were delineated between 4000 and 6000 m a.s.l.

Changes in Rongbuk lake and Imja lake in the Everest region of Himalaya [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
The Himalaya holds the world record in terms of range and elevation. It is one of the most extensively glacierized regions in the world except the Polar Regions. The Himalaya is a region sensitive to climate change.

Assessment of evolution and risks of glacier lake outbursts in the Djungarskiy Alatau, Central Asia, using Landsat imagery and glacier bed topography modelling [PDF]

, 2017
Changes in the abundance and area of mountain lakes in the Djungarskiy (Jetysu) Alatau between 2002 and 2014 were investigated using Landsat imagery. The number of lakes increased by 6.2 % from 599 to 636 with a growth rate of 0.51 % a−1.

Stratigraphic evidence for modern‐like glacier extents in south‐central Alaska within the last glacial period (MIS 3)

Boreas, EarlyView.
The last (Wisconsinan) glacial period was punctuated in North America by two glacial maxima, known as the Early and Late Wisconsinan glaciations. In Alaska, these maxima and their subsequent retreats have been the object of dating efforts to reconstruct local climatic events and compare them to global trends.

Characteristics and evolution process simulation of the Baqu gully debris flow triggered by ice-lake outburst in Luolong County of Tibet, China

Shuiwen dizhi gongcheng dizhi, 2021
The Baqu glacial lakes outburst debris flow is close to a station of the Sichuan-Tibet Railway, which may threaten the construction and running of the railway.
