In this paper, the first glacial lake in- ventories for the Third Pole were conducted for ~1990, 2000, and 2010 using Landsat TM/ETM+ data.Abstract:
article i nfo No glacial lake census exists for the Third Pole region, which includes the Pamir-Hindu Kush-Karakoram- Himalayas and the Tibetan Plateau. Therefore, comprehensive information is lacking about the distribution of and changes in glacial lakes caused by current global warming conditions. In this study, the first glacial lake in- ventories for the Third Pole were conducted for ~1990, 2000, and 2010 using Landsat TM/ETM+ data. Glacial lake spatial distributions, corresponding areas and temporal changes were examined. The significant results are as follows. (1) There were 4602, 4981, and 5701 glacial lakes (N0.003 km 2 ) covering areas of 553.9 ± 90, 581.2 ± 97, and 682.4 ± 110 km 2 in ~1990, 2000, and 2010, respectively; these lakes are primarily located in the Brahmaputra (39%),Indus (28%), and AmuDarya (10%) basins. (2) Small lakes (b0.2 km 2 ) are more sensitive to climate changes. (3) Lakes closer to glaciers and at higher altitudes, particularly thoseconnected to glacier ter- mini, have undergone larger area changes. (4) Glacier-fed lakes are dominant in both quantity and area (N70%) and exhibit faster expansion trends overall compared to non-glacier-fed lakes. We conclude that glacier meltwa- ter may play a dominant role in the areal expansion of most glacial lakes in the Third Pole. In addition, the pat- terns of the glacier-fed lakes correspond well with warming temperature trends and negative glacier mass balance patterns. This paper presents an important database of glacial lakes and provides a basis for long-term monitoring and evaluation of outburst flood disasters primarily caused by glacial lakes in the Third Pole.read more

Different glacier status with atmospheric circulations in Tibetan Plateau and surroundings
TL;DR: This paper found that the most intensive glacier shrinkage is in the Himalayan region, whereas glacial retreat in the Pamir Plateau region is less apparent, due to changes in atmospheric circulations and precipitation patterns.

TL;DR: In this article, the authors examined annual changes in lake area, level, and volume during 1970s-2015 and found that increased net precipitation contributes the majority of water supply for the lake volume increase, followed by glacier mass loss and ground ice melt due to permafrost degradation.

TL;DR: In this paper, the role of these lakes as terrestrial storage for glacial meltwater is unknown and not accounted for in global sea level assessments, and they use scaling relations to estimate that global glacier lake volume increased by around 48%, to 156.5 km3, between 1990 and 2018.

TL;DR: In this paper, the potential danger of outburst floods depends on various factors like the lake's area and volume, glacier change, morphometry of the glacier and its surrounding moraines and valley, and glacier velocity.

Glacier mass changes on the Tibetan Plateau 2003-2009 derived from ICESat laser altimetry measurements
TL;DR: In this paper, the authors employed data from the ICESat to estimate elevation and mass changes of glaciers on the Tibetan Plateau between 2003 and 2009, and found that a total annual mass budget of 15.6, 10.6 and 10.1 was estimated for the eight sub-regions sufficiently covered by ICESAT data which represents 80% of the glacier area on the plateau.

Increased mass over the Tibetan Plateau: From lakes or glaciers?
TL;DR: In this paper, the authors examined lake's water level and mass changes in the Inner Tibet Plateau (TP) and suggest that the increased mass measured by GRACE was predominately due to the increased water mass in lakes.
