Arctic deserts are also a thing (e.g. Iceland). The similarities tell the whole story:

  • Poor access to liquid water
  • Need to insulate body from temperature extremes, wind
  • Food sources are sporadically available at best
  • Need to minimize contact with ground or insulate feet

This is not to suggest that polar bears are similarly adapted to the Sahara. Rather, it's not a huge shift, but it's still a change.

in a similar vein rainforests do not have to be tropical, there are several temperate rainforests in europe of which the southwestern norwegian coast is apparently one
