“…Maximum ice thickness and duration on the Ob and Yenisiey rivers and other Arctic Russian rivers have decreased 178 , as has the period when the Kara Sea coastal zone has been ice-free due to later freeze and earlier melt timings 179 . Coupled with further reductions in Arctic sea-ice cover 180 , the capacity and distance that atmospherically deposited radionuclides and entrained contaminated river and estuarine sediments might be transported by river/sea-ice would be expected to decrease 181 .…”

Climate change interacts with the sources and cycling of contaminants, such as radionuclides, in the environment. In this review, we discuss the implications of climate change impacts on existing and potential future sources of radionuclides associated with human activities to the marine environment. The overall effect on operational releases of radionuclides from the nuclear and non-nuclear sectors will likely be increased interference or prevention of normal operations due to weather-related events. For certain radioactive waste dumped at sea and sunken nuclear submarines, the impact of climate change and ocean acidification on the release of radionuclides and their subsequent fate in the marine environment should be considered further. Fluxes from secondary sources of radionuclides in the marine and terrestrial environment and cryosphere will change in response to climate change impacts such as sea level rise, warming and changes in precipitation patterns. In addition, climate change impacts may increase the risk of releases of radionuclides from operational and legacy wastes on land to the marine environment. Overall, our synthesis highlights that there is a need to understand and assess climate change impacts on sources of radionuclides to the marine environment to meet environmental and management challenges under future climate scenarios.

“…Landfast ice usually occurs in October and collapse in late June [22,25]. The duration of the ice-free period in the studied region, as well as in the whole Arctic, has shown a significant increase (up to 15-75%) [40][41][42] during the last 40 years.…”

“…The ice-free period characteristics were derived from sea ice concentration satellite data from the US National Ice and Snow Center, NSIDC, Climate Data Records [59]. The identification of the ice-free period was carried out using a modified threshold method adapted for the Arctic coastal zone data [42,60]. The start/end dates of the ice-free period are presented as integers corresponding to the number of the day of the year, starting from January the 1st.…”

“…The most different among them is 5-3 cluster having a peak of erosion in 1982-1988, whereas all the other clusters have a peak of accretion (Figure 10d). Cluster-based segmentation of the accretional coasts captured a slight response of wave-impact intensification and subsequent reversal of sediment fluxes that may be exerted by drastic changes in sea-ice extent [42].…”

In recent decades, acceleration of coastal erosion has been observed at many key sites of the Arctic region. Coastal dynamics of both erosional and accretional stretches at Kharasavey, Kara Sea, was studied using multi-temporal remote sensing data covering the period from 1964 to 2022. Cross-proxy analyses of the interplay between coastal dynamics and regional (wave and thermal action) and local (geomorphic and lithological features; technogenic impact) drivers were supported by cluster analysis and wind–wave modelling via the Popov–Sovershaev method and WaveWatch III. Ice-rich permafrost bluffs and accretional sandy beaches exhibited a tendency towards persistent erosion (−1.03 m/yr and −0.42 m/yr, respectively). Shoreline progradation occurred locally near Cape Burunniy (6% of the accretional stretch) and may be due to sediment flux reversals responding to sea-ice decline. Although the mean rates of erosion were decreasing at a decadal scale, cluster analysis captured a slight increase in the retreat for 71% of the erosional stretch, which is apparently related to the forcing of wind–wave and thermal energy. Erosional hotspots (up to −7.9 m/yr) occurred mainly in the alignment of Cape Kharasavey and were predominantly caused by direct human impact. The presented study highlights the non-linear interaction of the Arctic coastal change and environmental drivers that require further upscaling of the applied models and remote sensing data.

“…Climatic features of the European Arctic are primarily determined by the influence of the northern part of the Atlantic Ocean. However, the YaNAO is located much farther east, and here the influence of the Atlantic is combined with the Arctic processes determined by the Kara Sea, which is covered with ice during most of the year [7], and the continentality of the climate intensifies to the east. Notably, relatively little research has been published regarding the climate of this region, which is an area of intensive shipping, fishery, and the largest hydrocarbon (petroleum and natural gas) basin in the world's natural gas production.…”

A Spatially Detailed Projection of Environmental Conditions in the Arctic Initiated by Climate Change

The environmental conditions of the Arctic are vulnerable to the effects of climate change. We focus on the territory of the Yamalo-Nenets Autonomous Okrug (YaNAO). The objective of this study is to project mid-21st century climate-driven changes in the state of climate and the natural environment in the YaNAO. For this purpose, the CMIP6 data models with the climate change scenario SSP5-8.5 were used. Climate change directly affects the statistics of extreme events and climatically driven phenomena, such as frosts and thaws, as well as avalanches and slush flows. Climate change causes changes in the Arctic environment, primarily due to permafrost degradation, leading to important modifications in events such as mudflows, cryogenic landslides, abrasion, erosion, suffusion, frost heave, solifluction, thermokarst, and others. In some cases, the intensity and area of these processes increase, such as heaving processes and thermokarst becoming more active by 2050. In other cases, the solifluction processes decrease in the south part of the YaNAO due to the discontinuous or sporadic permafrost distribution. Projected climatic changes will inevitably lead to the restructuring of the geosystems in YaNAO, creating risks for infrastructure in economically active territories.
