For those interested, there is a long thread on the Climate Change board on polar bears:

A new sub-population (genetically distinct) has been described on the southeast coast of Greenland. They apparently migrated south about 200 years ago.
The interesting thing about them is that they live in a glacial-front environment rather than living on sea ice during the winter. The authors (Laidre et al.) point out that even if Arctic sea ice disappears in the future this environment would provide a refuge.
Glacial ice supports a distinct and undocumented polar bear subpopulation persisting in late 21st-century sea-ice conditions
