During the just-ending northern hemisphere winter the ocean surface east of New England has rocketed to 11-13F warmer than normal in some locations. The warming - very persistent in this location the past 7-8 years - is part of a weakening Atlantic Meridional Ocean Current which is slowing the transport of warm Gulf Stream Water toward Europe. Instead waters are warming (and rising) off the Northeast U.S. Coast. Blocking the warm water transport of the Gulf Stream is the North Atlantic Warm Hole south-southeast of Greenland.
