In accordance with the observations results since 1881 through 2003 its average annual air temperature calculated to within 0,1º, holds 5-7 place (together with 1998 and 2003) is among the warmest years since 1880. It’s warmer than 2011 having 9-10 rank, but is notably colder than 2010, the average annual temperature of which is an absolute maximum.

The most rapid raising of air temperature in three last decades has been taking place here. In 2012 the average annual air temperature in the Arctic exceeded the norm  by 4-7 ° C, and in the north of the Kara Sea between the archipelagoes of Franz Joseph Land and Severnaya Zemlya – more than 7 º C. It was never before that  an anomaly of average annual air temperature  in the Northern hemisphere exceeded 5 º C.
