That a simple warming trend throughout the 20th century does not characterise arctic conditions is also confirmed by records of ice cover in the four seas that lie north of Siberia (Kara, Laptev, East Siberian and Chukchi); these show clearly that ice variability in these seas is dominated by a low frequency oscillation of frequency 60 ‐ 80 years that «places a strong limitation on our ability to resolve long term trends».
