Polar bears are one of the species that’s been hardest hit by climate change. But scientists have long thought the bears might be capable of effectively hibernating in summer, to save energy during a longer open water season. New research from the University of Wyoming disproves that hypothesis though. Merav Ben David is a professor of wildlife ecology and one of the authors of the new study. She told Wyoming Public Radio’s Stephanie Joyce that without hibernation, it’s an increasingly long and hungry summer for the bears.
