One of the notable aspects of climate change that has been observed is the further toward the poles one looks, the more pronounced global warming’s impact becomes. While the tropics have warmed somewhat, average temperatures in the Artic have soared: the North Pole was a full degree warmer than Seattle on Dec 30 2015, and while the contiguous U.S. broke a 3.3ºF (1.83ºC) above-average heat record for June of this year, Alaska saw a temperature record of nearly three times that level for the same month, at 9ºF (5.0ºC) above average.
