As climate change has accelerated, scientists have long believed that Canada’s far north would serve as polar bears’ last sanctuary.
No longer. New research from the University of Alberta has found that as their ice habitat disappears, polar bear populations in the Canadian Arctic Archipelago might be no better off than their southern counterparts.
The entire region’s polar bear population could face starvation and reproductive failure by 2100, crossing the “point of no return,” according to the study.
“The previous work on the long-term trends in polar bear habitat indicated that the high Arctic was a likely refuge for polar bears,” Andrew Derocher, a biology professor and coauthor of the study, said in an email.
