Spitzbergen There is still plenty of ice in the Arctic at the end of the long, dark winter, but in the summers more and more of the ice is melting away faster and faster. At the end of summer 1993, Arctic sea ice covered 7.5 million square kilometres; after a catastrophic collapse in September 2007, only 4.3 million square kilometres remained. Since then, the area of summer ice has recovered very slightly, but the ice is still thinning, setting it up for another catastrophic collapse. |
