The polar coverage of GISTEMP arises mainly from the fact that GISTEMP allows each weather station to contribute to an area of radius 1200 km around the station - this distance was determined by examining how temperature changes with distance in regions with good coverage (see Of Averages and Anomalies - Part 1B).

And since polar bears of the Barents Sea and adjacent Arctic areas appear to have survived this change to Holocence Thermal Maximum conditions, it challenges the notion that recent warming has been (or will be) too fast to allow polar bears to survive without huge changes in their present distribution (Amstrup et al. 2007).

In contrast to the polar regions, the network of lower latitude small glaciers and ice caps, although making up only about four percent of the total land ice area or about 760,000 square kilometers, may have provided as much as 60 percent of the total glacier contribution to sea level change since 1990s (Meier et al. 2007).
