An analysis of a NASA satellite survey of the Arctic shows sea ice coverage in 2002 was the lowest in the 20 years of satellite observations, New Scientist reported Friday.
The retreat was uneven, showing up particularly in areas north of Alaska, where temperature data confirms the warming predicted by climate models. It is also consistent with reports that sea ice is growing thinner.
"Climate is changing, the Arctic is changing rapidly, and it has significant effects on lower latitudes," said Mark Serreze, of the University of Colorado in Boulder.
