In search of polar warming

Summary

Greenhouse warming, although predicted to become especially pronounced in the polar regions, will be obscured there by the short-lived anomalies that are characteristic of polar climates. To detect a warming it then becomes necessary to examine and compare statistical parameters of such quasi-steady interludes. A new “change index (CI)” is proposed and used to demonstrate that a warming at four Alaskan airfields, reported by Bowling (1991), represented a distinct change from the temperature mean and/or variance of the preceding few years, and was followed by a slightly cooler regime that has persisted through 1994.
