•The average annual surface air temperature anomaly over land north of 60° N for October 2015-September 2016 (+2.0° C, relative to a 1981-2010 baseline) was by far highest in the observational record beginning in 1900; this represents a 3.5° C increase since the beginning of the 20th Century.
•Arctic temperatures continue to increase at double the rate of the global temperature increase.
•Extreme Arctic-wide air warm temperatures in winter 2016 (Jan-Mar) greatly exceeding the previous record; several locations showed January anomalies exceeding +8° C. These conditions were primarily due to southerly winds moving warm air into the Arctic from mid-latitudes and the presences of sea ice free areas to the northeast of Novaya Zemlya.
•Neutral to cold temperature anomalies occurred across the central Arctic Ocean in summer 2016; a condition which did not support rapid summer sea ice loss.
