2014 – 2015 Arctic Sea Ice Maximum Extent was Lowest yet Recorded

The National Snow and Ice Data Center in Boulder, CO, announced on 19 March 2015 that the 2014-2015 Arctic sea ice maximum extent was the lowest since record-keeping started in 1979. In addition, sea ice likely hit its maximum extent nearly two weeks earlier than in recent decades, on February 25, 2015. This happened even as unusually cold air and stormy weather occurred across the eastern half of the United States and Canada this past winter.

Sea ice grew to it’s maximum extent of 14.54 million square kilometers (5.61 million square miles) on February 25, 2015. If we added an additional 1.10 million square kilometers (425,000 square miles) of sea ice to the Arctic right now, we would be at the average sea ice extent for the 1981-2010 period.
