Fig.1 Annual cycle of Arctic north of 66.5#cod#x000b0;N sea ice concentration trends, 1979—2011 The gray bars show the annual cycle of mean sea ice concentration %.Trends % per decade are shown by month and averaged from Hadley Centre sea ice data north of 66.5#cod#x000b0;N solid line. Dots show trends that are statistically significant at the 95% level or better.
