The melting Arctic is already changing the ocean's circulation

In the far North Atlantic, scientists have uncovered new evidence that an unusual infusion of freshwater into the ocean may already be affecting the ocean's circulation. Mostly likely sourced from melting glaciers in Greenland or Arctic sea ice, the freshwater remains on the surface of the ocean for longer than denser saltwater. This could affect the ocean's natural process known as convection, in which northbound surface water becomes denser and colder, thus sinking then traveling south at great...
