Go check it out. An increase of average monthly temperatures in October for Barrow, Alaska is 7.2 C or a shocking 44.9 degrees F. in the course of 34 years. A study by scientists at the University of Alaska Fairbanks analysed several decades of weather information. These show that temperature trends are closely linked to sea ice concentrations, which have been recorded since 1979, when accurate satellite measurements began. In that period, the average annual temperature rose by 2.7°C. But the November increase was far higher − more than six degrees. And October was the most striking of all, with the month’s average temperature 7.2°C higher in 2012 than in 1979. Apparently these increases are not related to the sun as it is at its lowest in the sky in October, and by November, does not appear over the horizon. Evidence points to the heat from ice free water being driven by North winds and then released into the atmosphere. According to a study published in The Open Atmospheric Science Journal, August of 2014, this warmth is unprecedented in the past 34 years when we have had reliable satellite based sea ice data. Looking at the more recent past (1979-2012), the time period for which we have reliable satellite-based sea ice data, a substantial warming of 2.7°C has been observed at Barrow (Fig. 3). This warming is about an order of magnitude higher than the global value. The observed warming, however, is not evenly distributed over the course of a year. In Fig. (4) the temperature change by month for the time period 1979- 2012 of Barrow is presented. All months, with the exception of January, display a warming, which is especially strong in autumn (6.3°C), followed by spring (1.8°C), summer (1.5°C) and winter (1.2°C). October displays the maximum temperature increase (7.2°C), a remarkably high value for a time period of only 34 years.
