Dwindling Arctic Sea Ice

October 24, 2003
According to a new NASA study, Arctic perennial sea ice has been decreasing at a rate of 9 percent per decade since the 1970s. The changes in Arctic ice may be a harbinger of global climate change, says Josefino Comiso, researcher at Goddard Space Flight Center, in Greenbelt, Maryland. In a recent Journal of Climate paper, Comiso notes that most of the recent global warming occurred over the last decade, with the largest temperature increase occurring over North America.
