According to the press release, 2015 air temperatures were "well above average with temperature anomalies over land more than 2 degrees Fahrenheit above average, the highest since records began in 1900." The report shows that the Arctic continues to warm about twice as fast as other parts of the globe, a phenomenon called Arctic amplification.

Other key observations in the report card: Increasing air and sea surface temperatures, decreasing sea ice extent and Greenland ice sheet mass, and changing behavior of fish and walrus.
