Another factor that conspired to accelerate the ice loss this summer was an unusual atmospheric pattern, with persistent high atmospheric pressures over the central Arctic Ocean and lower pressures over Siberia.

But I believe there is little doubt that the record - breaking scale and potential destructiveness of Sandy is due in large part to the amplifying effects of warmer ocean temperatures, higher atmospheric moisture content, and unusual Arctic weather patterns.

The unusual pattern of atmospheric high and low pressure over and around the Arctic that has contributed to the recent snow and cold from Alabama to Washington, to East Anglia, England (and rain and warmth along the west coast of Greenland) is also an important influence on the shifting sheath of sea ice on the Arctic Ocean.
