The Canadian Arctic permafrost is thawing 70 years earlier than expected, a rate shocking a group of scientists who released the findings of their long-term study this month.
A research team affiliated with the University of Alaska Fairbanks observed three sites over a period of 13 years between 2003 and 2016, according to a brief of their findings. Researchers discovered that a series of unusually warm summers triggered the rapid thawing, which is occurring 150 to 240 percent above the average rate between 1979 to 2000.
