A new report just issued by NOAA says September's Arctic sea ice coverage was about 25 percent less than it was between 1981 and 2010. As America's only Arctic state, Alaska today faces unique challenges. One of those is the loss of permafrost, the frozen earth that serves as the foundation for huge portions of the state.
For the past decade, Sue Natali of the Woods Hole Research Center has been taking trips deep into the remote corners of Alaska's wilderness."This area has been thawing for several decades now," Natali said.
