Climate change impact on existing infrastructure built on permafrost is of concern to many engineers and scientists. Some studies predict widespread collapse of the existing infrastructure. Adapting structures in the permafrost region to climate change is an important contemporary issue. In this paper, we analyze impacts of permanent and seasonal thermal insulation on permafrost temperature. An analysis of the available data shows that permanent thermal insulation increases the permafrost temperature when the soil surface is exposed to seasonal air temperature variations and when the mean annual soil surface temperature is below 0°C (32°F).
