چکیده
Abstract Permafrost thaw is a challenge in many Arctic regions, one that modifies ecosystems and affects infrastructure livelihoods. To date, there have been no demographic studies of the population on permafrost. We present first estimates number inhabitants permafrost Circumpolar Region (ACPR) project changes as result thaw. combine current projected populations at settlement level with extent. Key findings indicate are 1162 settlements ACPR, accommodating 5 million inhabitants, whom 1 live along coast. Climate-driven projections suggest by 2050, 42% will become permafrost-free due to thawing. Among remaining permafrost, high hazard zones, where consequences be most severe. In total, 3.3 people ACPR currently degrade ultimately disappear 2050.

متن کاملImpacts of permafrost degradation on arctic river biogeochemistry
Over the next century, near-surface permafrost across the circumpolar Arctic is expected to degrade significantly, particularly for land areas south of 70°N. This is likely to cause widespread impacts on arctic hydrology, ecology, and trace gas emissions. Here, we present a review of recent studies investigating linkages between permafrost dynamics and river biogeochemistry in the Arctic, inclu...
متن کاملChanging climate: geothermal evidence from permafrost in the alaskan arctic.
Temperature profiles measured in permafrost in northernmost Alaska usually have anomalous curvature in the upper 100 meters or so. When analyzed by heat-conduction theory, the profiles indicate a variable but widespread secular warming of the permafrost surface, generally in the range of 2 to 4 Celsius degrees during the last few decades to a century. Although details of the climatic change can...
