“…During this time, the length change measurements were performed by GPS and by analysis of satellite images. The recent observations of the glacier tongue could be connected to earlier measurements by Aizen et al (2006Aizen et al ( , 2007 (Fig. 7).…”

“…In the recent past, results of glacier monitoring activities in Central Asia (except Kazhakstan and China) are mainly based on remote sensing techniques with a focus on geodetic area and volume change assessments (see Table 4) or front variation measurements (Aizen et al, 2007;Konovalov and Desinov, 2007;Niederer et al, 2007;Haritashya et al, 2009;Kääb et al, 2015;Narama et al, 2010;Hagg et al, 2013;Kriegel et al, 2013;Gardelle et al, 2013;Gardner et al, 2013;Ozmonov et al, 2013;Pieczonka et al, 2013;Khromova et al, 2014;Pieczonka and Bolch, 2015;Farinotti et al, 2015;Petrakov et al, 2016).

Abstract. Glacier mass loss is among the clearest indicators of atmospheric warming. The observation of these changes is one of the major objectives of the international climate monitoring strategy developed by the Global Climate Observing System (GCOS). Long-term glacier mass balance measurements are furthermore the basis for calibrating and validating models simulating future runoff of glacierised catchments. This is essential for Central Asia, which is one of the driest continental regions of the Northern Hemisphere. In the highly populated regions, water shortage due to decreased glacierisation potentially leads to pronounced political instability, drastic ecological changes and endangered food security. As a consequence of the collapse of the former Soviet Union, however, many valuable glacier monitoring sites in the Tien Shan and Pamir Mountains were abandoned. In recent years, multinational actors have re-established a set of important in situ measuring sites to continue the invaluable long-term data series. This paper introduces the applied monitoring strategy for selected glaciers in the Kyrgyz and Uzbek Tien Shan and Pamir, highlights the existing and the new measurements on these glaciers, and presents an example for how the old and new data can be combined to establish multi-decadal mass balance time series. This is crucial for understanding the impact of climate change on glaciers in this region.

“…Violation of both the fourth and fifth assumptions, the lack of anthropogenic influence and the massive water storage capacities of these lakes may prevent or slow desiccation. While more stable than other smaller regional lakes, these lakes are currently shrinking as a result of climate change, in some cases compounded by anthropogenic use (Aizen et al, 2007;Gao et al, 2011;Micklin, 2007;Qin and Huang, 1998). (Note that paleolimnologic evidence suggests that the Aral Sea has desiccated in the past (Aizen et al, 2007)).…”

We do not intend to minimize anthropogenic changes to these lakes, but rather emphasize the importance of managing water resources in basins that are likely to be sensitive to natural climate perturbations.…”
