(Space.com) - New research from NASA and the National Snow and Ice Data Center (NSIDC) in Colorado measured Arctic sea ice cover on March 22, during what should've been its annual peak. In conclusion, the agency reported seeing 5.53 million square miles (14.33 million square kilometers) of sea ice — for context, that's the lowest Arctic winter sea ice levels have ever been.
