Meltdown: Ice Cracks at North Pole

Satellite images of the Arctic show large openings in the perennial ice cover, yet another consequence of greenhouse warming, scientists announced this week.



The Arctic’s thick perennial sea ice typically survives the warmth of the summer and lasts through the year. But satellite images taken in late August show that up to 10 percent of the perennial sea ice has been fractured by summer storms. The surprising change involves an area larger than the size of the British Isles.
