Hemisphere-wide implications’: Nasa warns temperatures in Europe could plunge if Arctic warming causes major ocean current to reverse

Massive buildup of freshwater could be released into Atlantic, disrupting currents that keep western Europe warm   

A major ocean current in the Arctic could reverse amid warming temperatures, a change which would bring significantly colder weather to western Europe, scientists at Nasa have warned.

The circular current, called the Beaufort Gyre, moves in a clockwise direction around the western Arctic Ocean, north of Canada and Alaska, where it naturally collects freshwater from glacial melt, river run-off and precipitation.
