Climate change is accelerating the melting of ice in Greenland at an alarming rate, with serious implications not only for the Arctic, but also for the global climate, including Europe. According to a study led by researchers at the University of Barcelona, extreme melting episodes—periods when large areas of snow and ice melt rapidly—have been about twice as frequent during summers in recent decades compared to the period 1950–1990.
Greenland will at some point in the future become the new North Pole of coldness once the Arctic ice drops low enough, affecting how the weather circulates. And its ice is melting too. I don’t even think we have good simulations of what that will do in weather systems and in further feedbacks.
