Climate change has resulted in permafrost degradation in numerous locations across the Arctic. The effects of climate change are exacerbated in areas of intensive human activity, particularly large industrial centers on permafrost. We used a combination of modeling techniques and field observations to evaluate how changes in climatic conditions have affected permafrost geotechnical properties in Russian large urban settlements such as Norilsk, Salekhard, Yakutsk, and Anadyr. The results show that there have been substantial decreases in foundation bearing capacity in all of these cities on permafrost from the 1970s to present. The projected changes under the six selected climate models show further decreases in foundation bearing capacity by the year 2050.
