Fossil results indicate polar bears survived last global warming deglaciation in Siberian and Canadian refugia
Polar bears are a familiar sight to many through the media as we see evocative images of singular bears floating on isolated ice rafts as they face the harsh realities of climate change shrinking sea ice in the Arctic. Their range is significantly impacted by the presence of perennial sea ice—that which survives at least one summer melt season. Simulations suggest polar ice cover is predicted to disappear during summer months by 2050, meaning this apex predator is increasingly being threatened by extinction due to habitat loss.
