GREENBELT, Md., Oct. 24 (UPI) -- In a case of polar opposites, as arctic sea ice shrinks, Antarctica's sea ice at the other end of the globe is growing, a NASA study says.
While a steady and dramatic decline in the sea ice cover of the Arctic Ocean has been observed during the last three decades, something more complex is happening around Antarctica where the total extent of sea ice surrounding the continent in the Southern Ocean has grown by roughly 6,600 square miles every year during the same period, NASA scientists said.
