Scientists say they now have unambiguous evidence that the warming in the Arctic is accelerating.
If this process continues, it will extend the melting season for Arctic ice, delaying the onset of winter freezing and weakening further the whole system. "You start affecting the temperature gradient between the Arctic and equator which affects atmospheric patterns and precipitation patterns. Exactly how this is going to play out, we really don't know yet. Our research is in its infancy."
