A team of NASA and university scientists has detected an ongoing reversal in Arctic Ocean circulation triggered by atmospheric circulation changes that vary on decade-long time scales.
Watching winter winds whip across the Great Lakes may help scientists understand how much ice will form there, how thick it will be and where it will drift.
Arctic sea ice is on the decline, but does the dwindling icecap of the north signal real change for the Arctic and for the planet?
The loss of ice from Greenland doubled between 1996 and 2005, as its glaciers flowed faster into the ocean in response to a generally warmer climate.
