A temperature record from a lake core reveals that it is warming at average rate of 0.4°æ per century generally over the past 400 years at Barrow, but it is colding from 6800 aBP to 6900 aBP. Maximum entropy spectra analysis shows temperature fluctuation cycles of 33, 40, 29, and about 90 years at Barrow, . According to statistics and entropy analysis of monthly mean temperature from Barrow Meteorological Observatory in 1921-1994, there are cycles of 4 months, 6 months, 14 months, 16 months, 3 year, 4 years, 7 years and 10 years in the recent temperature change..
