Arctic sea ice is beginning to melt and the end of spring is drawing near. Mating season is over for polar bears as is the gorging on young seals in most regions as weaned pups head into open water to feed for themselves. Only predator-savvy adult and subadult seals remain on the ice while they moult a new hair coat, so successful hunts by most polar bears will become more and more uncommon (e.g. Obbard et al. 2016).
