Sea ice at record low

USA Today =- There is now less sea ice on Earth than at any time on record. Ice in the Arctic and Antarctic melted to record low levels in January, scientists reported this week. Sea ice is frozen ocean water that melts during the summer and refreezes in winter. It floats on top of the ocean. Arctic sea ice this January averaged 5.17 million square miles, the lowest for the month in the 38-year sea ice record, the National Snow and Ice Data Center said. That is 100,000 square miles less than the previous January record low set just last year.
