Drunken forests, phenomenon caused as the permafrost melts as a result of Global Warming

Drunken Forests in Fairbanks, Alaska. This phenomenon is caused by the permafrost melting beneath the trees; the result is that they lean alarmingly. Northern Alaska has warmed by 6 degrees C. in the past 40 years, due to global warming. The once solid permafrost is starting to melt with shocking consequences for any infrastructure: roads, homes, pipelines etc. Most recent studies predict permafrost will disappear across the whole of Alaska in the next 60 years casing unprecedented damage.
