Global Warming? It now seems like Global Cooling!

I find it awkward to find Atlanta frozen. Aren't we having problems with Global Warming? It now seems like we are having Global Cooling!

Shouldn't Atlanta be frozen in the winter? I know that the town is known as Hotlanta, but you can't compare cold temps against AGW, it happens.

Wow! I didn't know that it was so warm up there. Your information was very helpful. Thank You.

Uh, right, so it is cold where you live so that means global warming is a hoax!

Check out how warm it has been up North, like last winter, in a pattern that will likely become the norm:





Record low sea ice:





Arctic sea ice loss linked to severe U.S. winters

In the atmosphere section of the lengthy report, the authors write: "There is evidence that the effect of higher air temperatures in the lower Arctic atmosphere in fall is contributing to changes in the atmospheric circulation in both the Arctic and northern mid-latitudes. Winter 2009-2010 showed a new connectivity between mid-latitude extreme cold and snowy weather events and changes in the wind patterns of the Arctic; the so-called Warm Arctic-Cold Continents pattern."

Two of the three authors of the atmosphere section of the report - Jim Overland of NOAA and Muyin Wang of the University of Washington - published a study last year on changes in atmospheric circulation related to Arctic warming and sea ice loss that came to similar conclusions, but without the benefit of observations during the anomalous winter of 2009-2010.

As detailed in the Report Card, a key reason why Arctic air temperatures have warmed in the fall and winter is because of greater sea ice loss during the summer melt season. Sea ice is white in color, and therefore it efficiently reflects incoming solar radiation, cooling the ocean and lower atmosphere. But when sea ice melts, the darker ocean waters are exposed to the sun, which boosts both water and air temperatures. This phenomenon is known as "Arctic amplification."

The ensuing warming raises the height of atmospheric pressure surfaces (known to meteorologists as "geopotential heights") over the North Pole.
