a Discovered a particular group of polar bears reside within the fjords in southeast Greenland Provides How can this species be capable of survive With the intensification of the local weather disaster.

Not like most polar bears, which hunt seals on sea ice and roam distant, this distinct group has tailored to reside in a smaller habitat and hunt on icy freshwater ice.

“In case you are concerned with preserving the species, then sure, our outcomes are hopeful” mentioned Kristin Lieder, a polar analysis scientist on the College of Washington’s Utilized Physics Laboratory. “However I do not suppose The glacier habitat will assist big numbers of polar bears. There’s not sufficient of it.”
