 Climate change has had adverse effects on Arctic natural ecosystems and threatened northern communities by disrupting their subsistence practices, limiting accessibility, and putting built infrastructure at risk. In this paper, we analyzed spatial patterns of permafrost degradation and associated risks to built infrastructure due to its loss of bearing capacity and for subsidence in permafrost regions of the Arctic. We used three coupled model intercomparison project, CMIP, six models under special report 245 and 585 scenarios to estimate changes in permafrost bearing capacity and ground subsidence between two reference decades, 2015 to 2024 and 2055 to 2064. We then used publicly available infrastructure databases to identify roads, railroads, airports, and buildings at risk of permafrost degradation and estimated contraspecific costs associated with damage to infrastructure. Our results showed that under the CMIP 6 SSP 245 scenario, 29 percent of roads, 23 percent of railroads, and 11 percent of buildings would be affected by perma.
