In very cold places, like Alaska, Northern parts of Canada and Europe, building infrastructure means building on permafrost, perennially frozen ground. Permafrost provides reliable foundations for buildings and highways as long as it remains frozen. But warming temperatures driven by climate change may threaten existing and new infrastructure founded on permafrost.

To help us understand the problems and potential solutions in this dynamic risk environment, we talk with Billy Connor, Director of the Arctic Infrastructure Development Center at the University of Alaska.
