To make a complex story simple, polar bears are threatened by habitat loss. We may hold onto polar bears as a species to the end of the century, but this is predicated on many hopeful elements.

Sea Ice and Climate Change

There is no contradiction for global warming to cause dramatic sea ice loss in the Arctic and a slight expansion in the Antarctic. There is no doubt in my mind that the implications for polar bears habitat loss are serious and sobering.

Sea Ice, Polar Bears, and Extreme Weather

Dr. Steven C. Amstrup

This summer's record low sea ice extent has prompted speculation about how polar bears will be affected. Because polar bears depend on sea ice to catch seals, less sea ice can only be bad for polar bears. But it's not just this year's record low that is cause for concern.

If greenhouse gases continue to rise, all models predict that the planet is headed to a future with an Arctic that is ice-free in the summer. The predictions of when this will occur vary by model, from as soon as a decade or two from now to closer to the end of the century.
