There’s the sea ice map for today. Where on that map is it possible for a polar bear to swim just 100 miles, let alone ‘hundreds’, in order to transit open ocean between land masses and ice floes? It is not possible and this story is just sheer BS.

Sea Ice means that open water is less than 15% of the area of an ice field.

If it's more than 15% it's open water ~ but what that means is that in the Arctic there's usually large amount of ice all over the place.
