Published online in Wiley InterScience (www.interscience.wiley.com). DOI:10.1002/joc.971 THE URBAN HEAT ISLAND IN WINTER AT BARROW, ALASKA

The village of Barrow, Alaska, is the northernmost settlement in the USA and the largest native community in the Arctic. The population has grown from about 300 residents in 1900 to more than 4600 in 2000. In recent decades, a general increase of mean annual and mean winter air temperature has been...
