What NASA Says Is Really Happening to the Arctic Ice Cap

(Fox News) - Many global warming activists point to changes in the arctic icecap as proof of the dangerous effects of man-made global warming. Now a report from NASA's Jet Propulsion Laboratory says those changes are in fact the result of natural ocean circulation patterns. A team of scientists used satellite and deep-sea pressure gauge data to monitor ocean patterns.

Says team leader James Morison of the University of Washington's Polar Science Center — "Our study confirms many changes seen in upper Arctic Ocean circulation in the 1990s were mostly decadal in nature, rather than trends caused by global warming."
