The bears are "more resilient to climate change and better-suited for warmer temperatures," paleontologist Larisa DeSantis said. However, due to climate change, they're becoming a lot more common. Polar bears, on the verge of extinction due to climate change, are frequently moving inland in search of food and mating with grizzly bears to create a hybrid animal that is more resilient to the warming world. Students will learn about extracting shale oil and gas through the process of fracking. A pizzly was first spotted when a researcher noticed a bear with the white fur of a polar bear, but the long claws, hump, shallow face and patchy brown fur of a grizzly.
