Climatologist: Sea Ice to keep shrinking
561548
Arctic sea ice next summer may shrink below the record low last year, according to a University of Washington climatologist. Ignatius Rigor spoke Monday at the Alaska Forum on the Environment and said global warming combined with natural cyclical changes likely will continue to push ice into the North Atlantic Ocean.

A faster-than-expected thaw of the Arctic is likely to open legendary short-cut routes between the Pacific and the Atlantic but experts say icebergs and high costs will prevent any trans-polar shipping boom.

A sea-surface cooling in the Pacific,  which may have contributed to strong hurricanes in the United  States and a freeze-up in China, could last at least until  mid-year, the U.N. weather body WMO said on Monday.
