    There is nothing mysterious about the cold blob. It’s due to the land ice in Greenland melting due to global warming. This ice runs into the ocean at greater and greater speeds, cooling off the water in that region. So that little bit of cooling is actually just a part of global warming.

      Might be that the melt runoff is at a greater rate than before where that cold blob was smaller/not there.

      If the cold blob continues to get bigger, the warm surface could get cut off.

        I’m guessing the water at the poles was already close to freezing temperatures.
        So it isn’t affected by melting ice.
        But at latitudes affected by the warm Gulf Stream, melting ice is colder than the surrounding water, so it would cool it down.
