Close-up view of a pool at Russell Lakes
State Wildlife Area (see Color Plate 17-26). Dark green

Intergovernmental Panel on Climate Change
(IPCC) suggested that the changes witnessed in
these regions would be far reaching and drive
feedback loops of global consequence (Anisi-
mov et al. 2007). The average surface tempera-
tures in the Arctic over the past 20 to 40 years
have increased at a greater rate than the global
average (McBean et al. 2005). This has been
accompanied by a reduction in the extent of sea
ice and permafrost (Anisimov et al. 2007). Such
processes could potentially have regional and
