GOLDEN VALLEY, Minn. - NASA scientists maintain we should all be concerned about what happening in the Arctic.  They say their satellites show the sea ice on the arctic ocean is melting at an alarming rate, which they believe is one of the most visible signs of a warming planet.

NASA officials say that 30 years ago, at the end of summer, ice covered some one million more square miles of the Arctic Ocean than it does now. They say that's roughly the size of Alaska, Texas and California combined.

KARE 11 Sunrise spoke with NASA Scientist Dr. Walt Meier about the melting and the consequences of a shrinking Arctic.
