Over the Arctic during the last few decades a decrease in annual precipitation and snow depths have been observed this decrease is especially pronounced during the winter months. This decrease was not only found over northern Alaska but also over the high latitude Canadian land stations and Russian drift stations. Satellite monitoring of North America snow cover has revealed a significant decreasing trend in mid-spring cover since 1972.
