"500 MILES FROM THE NORTH POLE -- The minimum summertime volume of Arctic sea ice fell to a record low last year, researchers said in a study to be published shortly, suggesting that thinning of the ice had outweighed a recovery in area."

"The study estimated that last year broke the previous, 2007 record for the minimum volume of ice, which is calculated from a combination of sea ice area and thickness.

The research adds to a picture of rapid climate change at the top of the world that could see the Arctic Ocean ice-free within decades, spurring new oil exploration opportunities but possibly also disrupted weather patterns far afield and a faster rise in sea levels."
