“…According to the results of field observations [65], the Potanin Glacier retreated 90 m between September 2003 and September 2009, a mean retreat rate of 15 m·year −1 . Therefore, we should agree with the suggestion that early 21st century retreat at the Potanin Glacier may be decelerating [35]. At the same time, faster retreat might have occurred after 2009 (compared with other valley glaciers of the region (Table 5) Table 4).…”

“…Generally, the differences between the GLIMS and our schemes of glaciation are caused by the difference in materials used: we based our field observations, including the latest expeditions There is very little information about the rates of retreat of the glaciers in the area of research. According to [35], from 1989 to 2009, the total area of glacier ice at the Tavan Bogd massif decreased from 213 to 204 km 2 , i.e., by 4.2%, over the 20 years [35]. This is much slower than our results for the northern slope of Tavan Bogd (7.1% for the 2001-2009 period).…”

“…Later, the glaciation of Mongolia was studied by Baast [30]. In the 21st century, the development of remote sensing, sometimes in combination with in situ observations, led to a number of new publications: [31][32][33][34][35][36][37][38][39] The Mongolian glaciers have been cataloged and mapped by Kamp et al [34,40]. Recently the glaciers of the region were included in the GLIMS (Global Land Ice Measurements from Space) database and the Randolph Glacier Inventory [34,41,42].…”

“…The Potanin and Alexandra Glaciers at Tavan Bogd saw oscillations and even slight advances in the 1930s, the 1960s, and the late 1980s; in 1987-2001, the Potanin Glacier retreated with an average rate of 43 m·year −1 [38]. The satellite-based study by Krumwiede et al [35] indicates that between 1989 and 2009, the Potanin Glacier receded by 516 m, a mean rate of 25.8 m·year −1 , and by 5.1% of its total length. Over the same period, the adjacent Alexandra Glacier receded by 653 m, a mean rate of 32.7 m·year −1 , and by 7.7% of its total length.…”

This research is based on multiyear in-situ observations, analysis of satellite and aerial imagery, meteorological data, and mass balance index calculations. Presently, 659 glaciers cover a total area of 322.1 km 2 . We identified four favorable, two neutral, and five unfavorable longer intervals of glacier development since 1940. A decelerating of glacial retreat took place in the 1960s and in the late 1980s/early 1990s. The strong decline in glacial mass between 1995 and 2009 resulted in a fast reduction of the glacial area (0.9% year −1 on the northern slope of Tavan Bogd, 1.5% year −1 at Mongun-Taiga), mostly due to the degradation of small glaciers; after 2009, the glacial loss slowed down. Large valley glaciers behaved asynchronously until recently, when their retreat accelerated rapidly reaching in some cases over 40 m·year −1 . Degradation of the accumulation zone and separation of the debris-covered parts of the glaciers are characteristic for the glacial retreat in the region of research. The time of reaction of the fronts of four valley glaciers of Mongun-Taiga and the northern slope of Tavan Bogd on climatic fluctuations is estimated between 11 and 20 years. Over the next decade, high rates of glacial degradation are expected.

“…Basing on those results the total area of the glaciation of Tavan Bogd in 1987 was estimated by 222.3 km 2 , also a rough estimate of the LIA area of the glaciers has been made (260 km 2 ) [44]. Since 1999 the glaciers of the north slope are continuously studied by the scientists of Saint-Petersburg state university (field observations and remote sensing) [45][46][47][48] In recent years, significant progress has been made in the study of the glaciers of Tavan Bogd due to the use of remote methods [53,54], in particular in the compilation of the second Chinese glacier Inventory [55] and GLIMS (Global Land Ice Measurements from Space) database and the Randolph Glacier Inventory [56].…”

The study is based on the results of long-term field studies, satellite and aerial data analysis. In the maximum of the Little Ice Age (LIA) 243 glaciers with a total area of 353.4 km2 were reconstructed. By the results of interpretation of Corona images by 1968 the number of glaciers increased (236), the total area reduced to 242 km2. In 2010 glaciation was represented by 237 glaciers with a total area of 201 km2. Thus, from the maximum of the LIA, the glaciation of the Tavan-Bogd mountains decreased by 43%, which is somewhat less than the neighboring glacial centers (Ikh-Turgen, Tsambagarav, Tsengel-Khayrkhan and Mongun-Taiga mountains). The probable cause is the predominance of larger glaciers relatively resistant to warming and higher altitudes. The effect of glacier size on their stability is supported by differences in the relative shrinkage of glaciers in different parts of the Tavan-Bogdo-Ola massif: the smallest decline occurred in the basins of the Tsagan-Gol (31.7%) and Sangadir (36.4%) rivers where the largest glaciers are located. On the contrary, on the lower periphery of the massif, where small glaciers predominate, the relative reduction was large (74-79%). On the background of the general retreat trend large valleys glaciers retreated faster in 1968-1977 and after 2010. In 1990-s the retreat was slow. After 2010 the glacial retreat was extremely fast. The retreat of glaciers in the last 50-60 years was caused by a trend towards a decrease in the amount of precipitation until the mid-1970s and a sharp warming in the 1990s and early 2000s.

With global warming, changes in glaciers and glacial lakes on the Tibetan Plateau call for a serious inspection. The Southeastern Tibetan Plateau (SETP) is a typical monsoonal marine glacier area that is extremely vulnerable to climate change. It is affected by both humid and warm Indian Ocean currents. Outlines of glaciers and glacial lakes in SETP have been extracted from Landsat satellite images with an automatic extraction method based on image compositing with Google Earth Engine and Random Forest algorithm. Alongside the outlines, meteorological data have been collected from 1990 to 2021. The results show that since 1990 the glacier area of SETP has retreated by about 2165.33 km2 (~25.28%), the glacial lake area has increased by about 36.41 km2 (~21.45%), and their number has increased by 477 (~27.32%). The reliability and scientific validity of this study is proven by comparison with existing glacier inventories. By analyzing the meteorological data, the inverse correlation between the glacier area and temperature has been found. Despite decreases in cumulative precipitation, the glacial lake level rise and consequent area expansion have been observed. A fitting equation for the response pattern of glacier changes to temperature and precipitation change is presented and will provide a basis for future studies.
