No urban heat island here

Here is the plot of temperatures for the past year at Eureka, Nunavat, from the Climate Prediction Center. Eureka is on the Fosheim Peninsula, on the north-central side of Ellesmere Island at 80N. Unlike other northern Canadian weather stations in the high Arctic, Eurerka is set back on a deep fjord, so has a less maritime climate that other sites. The middle plot shows the 30-day running mean, which smooths out the day to day variation in "weather", though as the top plot shows, temperatures have been monolithically above normal since early May.
