The Northeast Passage was expected to open first due to the Coriolis effect. As the world turns to the east, in the Northern hemisphere, flowing water will veer to the right. Warm, salty Atlantic water flows into the Arctic Ocean through the Barents Sea Opening between Norway and Svalbard, and the Fram Strait between Svalbard and Greenland, then bends right along the Arctic coasts of Norway and Russia.
Melting the West Antarctic Ice Sheet could save the Gulf Stream, a remarkable new study reveals. The vast icy mass in the southern hemisphere contains around 750,000 cubic miles of ice - enough to fill Wembley Stadium nearly three billion times. As it melts, the West Antarctic Ice Sheet sends salty water towards the North Atlantic, which helps the water stay dense enough to keep the crucial ocean current moving, the study authors reveal.
