      had N.A., Scandanavia, and upper Russia running cool by 5-degrees.

      Everybody else was hot by 3- to 5-degrees.

      Everybody human on big land.

      And the Arctic was hot at 5-degrees.

      BTW: Basically, the Arctic drives the planetary system for these types of big changes.

      Reduced reflection ==> temperatures soar.

      The models are looking really-really bad.

      •  It's not the Arctic it is the Tropics. (0+ / 0-)

        As warm air rises at the tropics it flows north and south high up in the atmosphere.  As this air cools somewhat some of it drops and helps form the Westerlies in both the North and South Hemispheres.  As this relatively warm air continues to the north and south it falls to the surface at the poles.  

        The warm air that rose at the tropics creates an area of low pressure there, the cold air at the poles forms an area of high pressure there.  Winds flow from high pressure to low pressure.  This is what drive Global Winds and this is why cold air invades the mid-latitudes.
