On September 27, 2014, the U.S. National Oceanic and Atmospheric Administration counted more than 35,000 Pacific walruses on a beach near Point Lay, Alaska. Scientists who study these walruses are worried by gatherings like this, or haul outs, as they are called, because Pacific walruses prefer sea ice to land. Scientists link this behavior to climate change, because as the climate warms and ice melts, the walruses are forced to move to land.
