Fig. 2 Mean annual air temperature trends in the Alaskan Arctic computed from the composite time series of anomalies and also according to CRU, BEST, GISS. (Ranging from 15 years (2001-2015) to the full record length (1921-2015), in 1 year increments. X axis is the onset year used to calculate the trend, the end of period is set to 2015. Horizontal colored dashed lines are corresponding trend values for 1951-2015. This figure shows only significant changes on 90% confidence level)
