An estimated 35,000 walruses have gathered on a beach in northwest Alaska as their natural resting grounds vanish due to climate change. Walruses usually gather to rest on sea ice offshore. But as Earth warms, they have begun appearing on beaches in recent years. The discovery of 35,000 walruses marks the largest number ever recorded on land. The Federal Aviation Authority has re-routed flights to avoid scaring the walruses amidst fears of a massive and deadly stampede.
