“…According to the latest data, there are 732 mountain glaciers in Kamchatka with a total area of 682.8 ± 29.0 km 2 (Khromova et al, 2021). The largest areas of glaciation in Kamchatka are the northern part of the Sredinny Range (465 glaciers with a total area of 255 ± 15 km 2 (Muraviev, 2020a)) and the Klyuchevskaya group of volcanoes (40 glaciers with a total area of 214.3 ± 6.6 km 2 (Muraviev, 2020b)). Cirque and cirque‐valley glaciers predominate, while the largest areas are occupied by cross‐valley and cirque‐valley glaciers (Muraviev, 2020b).…”

“…The main goal of our work is to identify trends in basic glaciological characteristics for the two large mountain–glacier regions of Kamchatka – the northern part of the Sredinny Range and the Kronotsky Peninsula. These areas of glaciation in Kamchatka are not influenced by modern volcanism (Muraviev, 2020b), therefore they are suitable for investigating the response of glaciers to climate change. In this article, we analyse the trends in glaciation total area from the middle of the 20th century to the present and their altitudinal distribution.…”

The reduction in the area and volume of glaciation in all mountain regions of the Earth has strongly accelerated for the last decades. In this work, we analysed the trends of the main climatic parameters which caused the glacier recession in the Kamchatka Peninsula. It was shown that the glaciers of the northern part of the Sredinny Range decreased by 125 km2 (35.6%) from 1950 to 2016–2017. The average rate of their reduction in the period from 2002 to 2016–2017 (1.45%/year) increased approximately 4.3 times compared to the period 1950–2002 (0.34%/year). The greatest reduction is observed in small glaciers with an area of less than 0.1 km2 and in glaciers with southeastern and southern expositions. On the Kronotsky Peninsula, the glacier area reduction for 1957–2019 was equal to 32.1 km2 (35.6%), and the rates were almost the same in the periods of 1957–2000 (0.61%/year) and 2000–2019 (0.67%/year). According to the data of weather stations and ERA5 reanalysis, it was shown that, in the ablation (summer) period the warming rate was minimal (0.3°C/10 years) and in the accumulation period a significant decrease in precipitation (5%–10%/10 years) was revealed in some areas. At the same time, a significant increase in the radiation balance was revealed in the warm season along with a tendency in downward shortwave radiation increase for the last two decades due to a decrease in cloud amount. These trends are in good agreement with the growth of the geopotential height over the North Pacific during the warm season in the 21st century, and with the growth of velocity divergence in the middle troposphere and the intensification of downward air movements. All this confirms an increase in anticyclone frequency in the warm season, which could be the cause of a radiation balance increase and, consequently, an increase in glacier ablation.
