A new study reveals that polar bears in Greenland are suffering from horrific injuries on their paws due to climate change. Researchers found that wet snow gets stuck between the pads of the bears' feet, freezing into blocks measuring up to 12 inches across. The debilitating ice balls can cause deep cuts and bleeding, making it difficult for the bears to walk or run.
