A Secret Polar Bear Population Has Been Found in an ‘Impossible’ Location

A secret population of polar bears in Greenland has been discovered in a seemingly impossible habitat – one that, for most of the year, lacks the floating platforms of sea ice the beasts use to hunt. The unusual group, which scientists previously thought was part of another nearby population, has been hiding in plain sight … Read more

Greenland polar bears are adapting to a less icy world

A newly discovered subpopulation of polar bears in remote southeastern Greenland have found a way to eke out a living under warm conditions similar to those forecasted for much of the Arctic later this century, scientists reported on June 16 in Science. Warming temperatures are causing sea ice, which polar bears depend upon for survival, … Read more
