What we can and canít say about Arctic warming and U.S. winters

Credit: Drew Angerer/Getty ImagesDecades of weather reports show a strong link between the polar blasts that have plunged the eastern United States in a deep freeze several times in the past few winters and the warming of the Arctic, where temperatures have been hitting unusual highs, a new study reports. Weather in the Northern Hemisphere depends largely on the temperature difference between the temperate middle latitudes and the Arctic. But the Arctic has been warming twice as fast as the rest of the globe as heat-trapping carbon dioxide and industrial emissions build up the atmosphere. How that Arctic amplification is affecting the weather further south is still a subject of hot debate. But since the trend started to show up around 1990, the Northern Hemisphere has seen more events like this Februaryís wild swings that drove temperatures above freezing north of Greenland while Europe froze. ďThe warm Arctic itself is contributing to these cold temperatures,Ē climatologist Judah Cohen, t
