New study: Sea ice loss likely no factor in cold Northern Hemisphere winters

New study: Sea ice loss likely no factor in cold Northern Hemisphere winters

The rapid loss of Arctic sea ice is a major driver of the warming trend sweeping across the Arctic in recent  years, but melting sea ice is probably not behind recent cold winters in parts of Europe, Asia, and the United States, according to a new NOAA study.
