The purpose of the study is to assess the current state of the Fedchenko glacier in the context of climate change. An assessment of the state of the Fedchenko glacier for the period 1977-2020 was carried out using images from the Landsat-2, 7 and Sentinel-2A satellites, as well as a retrospective analysis from 1933. The scientific novelty lies in the fact that over the past 50 years, for the first time, a detailed description of the glacier and its state during global warming has been provided, which makes it possible to determine the strategies and prospects for the study of Fedchenko glacier. The article showed that in the ablation zone, serious degradation is determined and large glacial lakes are revealed. Model-based predictions are a concern. It is emphasized that it is necessary to organize systematic expeditionary and stationary studies of the Fedchenko glacier.
Key words: Fedchenko glacier, satellite image, modeling, degradation, glacier area, climate change, glacial lake, monitoring.
