Starving Polar Bears are Mating with Grizzlies and Creating 'Pizzly They hunt for seals by finding their dens or sitting next to gaps in the ice, waiting for the unsuspecting prey to pop up. Even if greenhouse gases were curbed immediately, sea ice would likely continue to decline for several decades because large-scale changes take a long time to propagate through Earths climate system.
