|Arctic sea ice is shrinking at a rate much faster than scientists ever predicted and its collapse, due to global warming, may well cause extreme weather this winter in North America and Europe, according to climate scientists. Decades ago, Arctic ice covered about 6 million square miles of sea in the winter, and would shrink to about 3 million square miles in the summer. The rate of summer melt increased enormously around 2005, and today scientists say Arctic ice covers about 1 million square miles. "This is a very small amount of ice indeed," said Peter Wadhams, an ocean physics professor at the University of Cambridge. Wadhams said that while Arctic ice used to build up over many years, new ice formations are now breaking up and melting each summer. "I think that we can expect in the next few years is further collapse leading to an ice-free Arctic in summer," Wadhams said.|
