  •  That summer arctic storm (3+ / 0-)

    pushed most of the ice breakup into the Atlantic.  I was just thinking that melt might of contributed to the rise.

    •  The seas north of Iceland have been stormy (4+ / 0-)

      There were many storms, not just that big one. The overall pattern of many more than average storms is related to the NAO. Research has shown that the JFM NAO is critical to sea level anomalies, but the summer NAO surely has an effect, too.

      The loss of Arctic sea ice affects the atmospheric circulation, so that might be a link.

      look for my eSci diary series Thursday evening.

      •  How does that effect the evaporation and humidity? (1+ / 0-)

        Ice is a good insulator.  An ice covered arctic is like a head with a stocking cap.  Water heat energy can't couple to the atmosphere.

        But a low ice arctic is like football player in winter taking of his helmet.  The heat steams off the head visibly.

        Storms and wind stir up waves and drive big swells and white caps.  Waves break onshore, and a ton of water is thrown up into the air, vastly increasing surface area.

        That evaporation should shed heat and raise humidity.  So where does that extra water vapor fall?  And as snow or rain?
