More than 40 percent of the world's permafrost—landscape covered in frozen soil—is at risk of thawing even if the world succeeds in limiting global warming to the international goal of 2 degrees Celsius, according to a new study.

Currently, permafrost covers about nearly 5.8 million square miles, and scientists found as much as 2.5 million square miles of that could thaw—about twice the area of Alaska, California and Texas combined—in a 2 degree Celsius scenario. Thawing would be more limited if warming can be held to 1.5 degrees Celsius, but could still affect 1.8 million square miles.

Chief Eddie Hoffman Highway, seen on June 28, is the main thoroughfare in Bethel, and one of few paved roads. It has become a roller coaster of a ride over the past couple of years. The state Department of Transportation is studying whether heaving from the thaw-freeze of permafrost is a factor. (Lisa Demer / Alaska Dispatch News)

Craig Rogers, a longtime electric utility lineman in Bethel seen here on June 28, says his own home settled unevenly on a new pad built up with 138 dump truck loads of dirt. This corner sank 2 feet into the ground. As a final step to even it out, he inserted wedged shims of wood underneath. (Lisa Demer / Alaska Dispatch News)

Permafrost causing heaves in roads in Alaska has been going on for decades. It is nothing new. Go read the story of the construction of the Alaska Highway during WW2 and the problems they had with permafrost.
