Polar bears can't cope with food loss by entering hibernation-like state – study

Bears have no special ability to minimise energy loss during increasing periods of fasting brought on by climate change, as some previous research had suggested

A study of an Alaska polar bear population in summer concludes the bear's biology will not help stave off starvation in the face of global warming.

The study of southern Beaufort Sea polar bears by university, federal and private researchers over three years concludes they have no special ability to minimise energy loss during increasing periods of fasting brought on by climate warming, less sea ice and fewer hunting days.
