NASA found a way to track ocean currents from space. What they saw is troubling

There has been growing concern, of late, that one predicted consequence of a changing climate — the slowing of the great “overturning” circulation in the Atlantic Ocean — is already starting to happen...[In] a new paper... researchers from NASA’s Jet Propulsion Laboratory and the University of Texas at Austin use a new and sophisticated tool — the “Gravity Recovery and Climate Experiment” satellites, or GRACE — to confirm some pretty odd behavior in the circulation in 2009 and 2010 that has also been linked to a sudden and extreme 4-inch sea-level rise on the East Coast.
