February is mid-Winter in the Arctic and temperatures should be in sub-zero ranges but not again this year. Wild temperatures are being recorded in the far north of Greenland even during its 24-hour darkness. The Danish Meteorological Institute (DMI), which manages a weather station just 400 miles from the North Pole, has recorded temperature above freezing yesterday. Similarly, NOAA just released an Arctic Report Card on the environmental changes underway there.

Wild temperatures aren't restricted to the Arctic. According to the American Geophysical Union (the AGU):

"Boston hit 70°F yesterday February 21st, which is only the third 70F degree temperature recorded in February since records began being recorded in 1872 in Massassechutes. Likewise, New York City had its warmest February ever recorded with a 78F degree measurement in Central Park on Wednesday."

A recent study in Nature calcuated the Arctic variables impacted by climate change and concluded that the:

"warmest midwinter temperatures at the North Pole have been increasing at a rate twice as large as that for mean midwinter temperatures at the pole. This enhanced trend is consistent with the loss of winter sea ice from the Nordic Seas that moves warm air over this region northwards making it easier for weather systems to transport this heat polewards. These situations may become more pronounced as these midwinter warming events become more frequent as the region transitions towards warmer and wetter winters" .

Like the increased frequency of severe hurricanes and superstorm events that are driven by a warming atmosphere, we are now experiencing the effects of a changing climate in 'real time'.
