The Arctic Ocean Is Becoming More Like the Atlantic Ocean

The Arctic is undergoing an astonishingly rapid transition as climate change overwhelms the region. New research sheds light on the latest example of the changes afoot, showing that parts of the Arctic Ocean are becoming more like the Atlantic. Warm waters are streaming into the ocean north of Scandinavia and Russia, altering ocean productivity and chemistry. That’s making sea ice recede and kickstarting a feedback loop that could make summer ice a thing of the past.
