Warming shrinks Arctic Ocean ice to 2nd lowest on recordIce in the Arctic Ocean melted to its second lowest level on record this summer, triggered by global warming along with natural forces, U.S. scientists reported Monday. The extent of ice-covered ocean at the North Pole and extending further south to Alaska, Canada, Greenland and Russia reached its summertime low of 1.4 million square miles (3.7 million square kilometers) last week before starting to grow again. Arctic sea ice reaches its low point in September and its high in March after the winter.
