evidence: Polar bear population discovered that can survive with little sea ice [...] An isolated population of polar bears has been discovered in southeast Greenland1, which is free of sea ice for most of the year. Polar bears (Ursus maritimus) typically need sea ice to survive, so the discovery is raising hopes that some members of the species might survive the loss of ice caused by climate change. [...] Correction 20 June 2022: A previous version of this story incorrectly stated the number of adult females in the group; and a previous version of the headline incorrectly stated that the bears could survive without sea ice.
