“…In contrast to reports from many other regions of the globe (e.g. Li and Li, 2014;Fischer et al, 2015;Paul and Mölg, 2014), glacier aspect showed no statistical correlation with any of the glacier change parameters, which may result from the summertime midnight sun over Svalbard and the more balanced insolation on slopes with northern and southern aspects, compared to midlatitudes. Pearson correlation coefficients of glacier change parameters against other parameters and glacier geometry variables are given in Table 3.…”

Svalbard is a heavily glacier-covered archipelago in the Arctic. Dickson Land (DL), in the central part of the largest island, Spitsbergen, is relatively arid and, as a result, glaciers there are relatively small and restricted mostly to valleys and cirques. This study presents a comprehensive analysis of glacier changes in DL based on inventories compiled from topographic maps and digital elevation models for the Little Ice Age (LIA) maximum, the 1960s, 1990, and 2009/2011. Total glacier area has decreased by ∼ 38 % since the LIA maximum, and front retreat increased over the study period. Recently, most of the local glaciers have been consistently thinning in all elevation bands, in contrast to larger Svalbard ice masses which remain closer to balance. The mean 1990-2009/2011 geodetic mass balance of glaciers in DL is among the most negative from the Svalbard regional means known from the literature.Published by Copernicus Publications on behalf of the European Geosciences Union.

“…). Li and Li () analysed 487 modern glaciers and their corresponding LIA glacial advances in the central Tian Shan, and found that the relative area of shrinkage of glaciers are affected strongly by glacier size: small glaciers tend to undergo greater change due to their relatively smaller area of accumulation. The areas of modern glaciers in the TK and SR valleys are about 2.1 and 7.6 km 2 , respectively.…”

“…This method averages the elevation of the glacier terminus and highest elevation within the glacier valley to obtain the ELA. The elevations were derived from 1: 50 000 topographic maps with contour interval of 20 m. Previous studies on small valley glaciers in Central Asia demonstrated that the TSAM‐derived ELAs fit well with observational ELAs (Benn and Lehmkuhl, ; Li and Li, ), and this method has been applied in several recent studies on the glacial history of the Tian Shan (e.g. Li et al ., , ; Lifton et al ., ; Chen et al ., ; Li et al ., ).…”

We constrained glacial chronologies in three valleys on the southern slopes of the Nalati Range in the central Tian Shan, China: the Takelakete, Aiken and Sairenwuxunsala valleys, using 10Be surface exposure dating. Our 10Be exposure ages constrain three glacial events during 72.8 ± 3.8–59.9 ± 3.5 ka, 55.4 ± 3.0–34.9 ± 2.1 and 0.29 ± 0.17–0.27 ± 0.20 ka, corresponding to Marine Oxygen Isotope Stages (MIS) 4 and 3, and Little Ice Age (LIA), respectively. Glaciers have been restricted from composite valley glaciers and piedmont glaciers during MIS 4–3 to confined valley glaciers during MIS 3, to small valley glaciers during the LIA, and to hanging and cirque glaciers at present. This pattern of glacial change is broadly consistent with other glaciated areas across the Tian Shan. Extensive glacial advances during MIS 4 and 3 were probably driven by enhanced precipitation brought by the westerlies. Compared to MIS 3 glacial advance, lower temperature may counteract the effect of relatively lower precipitation to drive a similar or even larger glacial advance during MIS 4. Glacial advances were limited during MIS 2, probably reflecting enhanced arid conditions in the Tian Shan caused by the weakened westerlies and strengthened Siberian High.

“…Results show that topographical glacier parameters exercise great controls on mutual variations and, thus, the response of the glacier to the similar climatic environment [14].There are important studies in the literature examining these effects (elevation, slope, aspect, etc.) that cause heterogeneity on glacier retreat [14,20,[32][33][34]. The previous study especially focused on the topographical analysis of glacier retreat and glaciation on Mount Agri [34].…”

Investigating the causes of the spatial heterogeneity of glacial changes offers vital information about glacial behavior and provides forecasting ability to define where glacier retreat may occur in the future. This study was designed to determine the spatial distribution of Ağrı Mountain glacier vulnerability. The main goal of the current study was to assess the forecasting capabilities of Geographical Information System (GIS)-based Multi-Criteria Decision Analysis (MCDA) for determining the location of the mountain glacier retreat. To estimate the glacier retreat, the following criteria were selected: elevation, aspect, slope, direction, and glacier surface temperature anomaly (GSTA). The entropy method was used for weighting the criteria for the evaluation of the vulnerable areas of the glacier. The results of this method clearly indicate a strong relationship between GSTA, direction, and elevation criteria and glacier retreat. The glacier vulnerability map was created by synthesizing criteria layers with their weights. The vulnerability map provided a consistency of 77.8% in the short term and 92.1% in the long term. In the study, the priority melting zones were determined and glacial retreat locations were forecasted in 10-year periods.
