“…According to Fig. 6, 1996/97 (from the end of summer of 1996 to the end of summer of 1997) had a positive mass balance, and the equilibrium line altitude was 5530 m, while 2000/01 had a negative mass balance, and the equilibrium line altitude was 5660 m. The equilibrium line altitude in 2007 was estimated to be 5650 m by a DEM thinning observation (Shangguan et al, 2008). SAR images from late summer of 1997, 2001, and 2007 are shown in Fig.…”

“…By measuring the distance between glacier and markers surrounding the glacier, it had been found that the glacier terminal retreating ratio was 7-10 m/a from 1994 to 2001 [11]. In this work, the digitized topographical map derived from aerial photographs taken in 1974 and the glacier terminal position data measured with differential GPS data were imported to ArcGIS, and the length of Kangwure Glaciers in the Tibetan Plateau have been retreating during the past few decades resulting from global warming [19,27,28]. Large numbers of field monitoring confirmed that glaciers in the regions of Everest and Mt.…”

This paper calculated and evaluated the area and ice volume changes of Kangwure Glacier in Mt. Xixiabangma, middle of Himalayas in the past 3 decades, based on the field survey of glacier boundary position by differential GPS and glacier depth by Ground Penetrating Radar (GPR), together with the topographic map and remote sense data. The studied data showed that the Kangwure Glacier has experienced significant mass deficit since the 1970s, with 34.2% of area loss, 48.2% of ice volume loss and 7.5 m of average thickness decrease. This result revealed that the ice volume loss of Himalayan glaciers was more serious than expected. Analysis of meteorological data from two weather stations in the region of Mt. Xixiabangma, shows that the air temperature of this region has risen from the middle of the 20th century to the beginning of the 21st century. Significant retreat of Himalayas glacier driven by climatic warming will have a remarkable impact on hydrology and ecosystem.

“…The elevation increased by an average of ~4.60 m, or 0.19 m a -1 , corresponding to a tongue advance of 16.9 m from 196916.9 m from to 199316.9 m from (PU et al 1998YAO et al 2007). After 1993, the ice surface elevation decreased ~1.62 m (0.54 m a -1 ) from 1993 to 1996 and decreased by ~11.0 m (1.1 m a -1 ) from 1996 to 2007, corresponding to a tongue retreat of 93.9 m between 1993(SHANGGUAN et al 2008. Referred to LIU et al (1999), 1°C temperature rise could lead a rise of the ELA of only 58 m. It seems that glaciers of this type are more sensitive to precipitation change.…”

“…The worldwide extent of glacier retreat between 1884 and 1978 was proportional to the extent of global warming (0.66±0.1 K) in the same period, and it is estimated that the total area of the world's mountain glaciers will decrease by 1/3-2/3 in the 21st century (Oerlemans and Fortuin 1992;Oerlemans 1994). In Western China, most glaciers have experienced a strong reduction in the mass because of global warming since the early 20th century, and the significant glacier retreat have been reported since the 1980s (ZHANG and YAO 1998;LIU and KANG 1999;SHI and LIU 2000;SHI 2001, LIU et al 2003SHANGGUAN et al 2008;LI et al 2010).…”

Glaciers in the Tomor region of Tianshan Mountains preserve vital water resources. However, these glaciers suffer from strong mass losses in the recent years because of global warming. From 2008 to 2009, a large-scale scientific expedition has been carried out in this region. As an individual reference glacier, the tongue area of Qingbingtan glacier No. 72 was measured by the high precise Real Time Kinematic-Global Position System (RTK-GPS). In this paper, changes of the tongue area of Qingbingtan glacier No.72 has been studied based on topographic map, remote sensing image and the survey during 2008-2009 field campaign. Results indicated that the ice surface-elevation of the tongue area changed -0.22±0.14 m a -1 from 1964 to 2008. The estimated loss in ice volume was 0.014±0.009 km 3 , which represented a ~20 % decrease from the 1964 volume and was equivalent to average annual mass balance of -0.20±0.12 m water equivalent for the tongue area during 1964-2008. Terminus retreated by 1852 m, approximately 41 m a -1 , with the area reduction of 1.533 km 2 (0.034 km 2 a -1 ) from 1964 to 2009. Furthermore, the annual velocity reached to ~70 m a -1 . Comparing with the other monitored glaciers in the eastern Tianshan Mountains, Qingbingtan glacier No.72 experienced more intensive in shrinkage, which resulted from the combined effects of climate change and glacier dynamic, providing evidence of the response to climatic warming.
