Temperature and sea ice concentration measurements indicate a significant climate change in recent decades in the Western Arctic. Western Arctic temperatures have increased the temperature rise varies significantly from one season to another and over multi-year time scales. At the same time the sea ice concentration has decreased in our investigation area extending over a major portion of the southern Beaufort Sea. We investigated changes during the 23 years period from 1972 to 1994.

This study was supported by a grant from the State of Alaska to the Alaska Climate Research Center, University of Alaska, Fairbanks, and a grant from CIFAR, NOAA, . Michael Robb and Brian Hartmann helped with the data reduction; to both our thanks. We would also acknowledge our collaborators from NOAA in Boulder, namely E. Dutton, R. Stone and J. Harris and the National Ice Center (NIC) for providing ice concentration data. Special thanks also to the anonymous reviewers of this paper.
