Melting AK Permafrost Causing Major Infrastructure Issues

Alaska house sinking due to melting permafrost.
This article from KNBA out of Alaska is really interesting. In Alaska, infrastructure such as bridges, roads, buildings and runways have been built on permafrost- soil that became frozen from hundreds to thousands of years ago and remains frozen year-round.

Fairbanks used to have winters that stayed below zero degrees for months at a time. Reportedly due to climate change, the winters are much warmer now. And that's thawing out the permafrost. Which is playing havoc with transportation facilities such as roads. And costing a lot of money in maintenance and preservation.
