What Do Polar Bears Have To Do With Climate Change?
Due to changes in the amount and location of summer sea ice, Andrew Derocher, curator of the University of Alberta Museums Mammology Collection
, and a team of researchers have found that polar bears facing a long-distance swim are endangering their lives. While some of the bears are well equipped for swimming, the youngest, oldest and skinniest bears are more vulnerable to the harsh water conditions over extended distances. Greenhouse gas emissions linked to global warming has been seen as the trigger for this drastic change of habitat for the polar bears according to Derocher’s study.
