Davis Strait polar bear habitat higher now than in 1979 and early 1980s
The Davis Strait polar bear subpopulation is said to be ‘vulnerable’ to the supposed effects of global warming because, like Hudson Bay, Davis Strait sea ice retreats every summer, leaving polar bears on land for several months.
However, Davis Strait bears have been upgraded to ‘stable’ status, according to the latest table (2013) issued by the IUCN Polar Bear Specialist Group (see their boundary map for Davis Strait bears below). Recent development of sea ice in the region can only improve that rating.
Yeah, all that sea ice is tragic, isn’t it?
