From Maine to Delaware, the coastal U.S. Northeast is heating faster than most regions of North America thanks to the unusually fast-rising temperatures in the North Atlantic Ocean, and alterations in wind patterns that are now tending to send the warmth to the U.S. coast instead of the other way. Not only are Northeastern winters getting warmer, as long projected by climate models, but significant and rapid summer warming is happening too. The Atlantic Meridional Overturning Circulation (AMOC), a system of long-distance Atlantic currents, is slowing down (see previous posts) with one consequence being even more heating of the ocean off the Northeast coast.
