Ice Melt Impacts Polar Bears

Guest: Blaine Griffen, Associate Professor of Life Sciences, BYU A few months ago a National Geographic video of a starving polar bear went viral and sparked a debate about the effects of climate change and melting Arctic ice. If you’ve seen that video, you remember it: that poor emaciated polar bear dragging a leg, rummaging through an empty trash can before collapsing on the ground. Before that video went viral, BYU biologist Blaine Griffen had a study already in the works on the challenge polar bears face getting enough food when seasonal ice melts faster than it used to.
