An emaciated polar bear sleeps on a bed of moss, on the tiny island of Moseøya, north west of Spitsbergen, in the High Arctic archipelago of Svalbard. With its seasonal melting of the pack ice, summer is always a challenging time for polar bears. With less ice, seals are harder to catch and bears rely almost exclusively on the fat reserves accumulated during their winter hunts. Sadly, with the changing climate, summer has become increasingly deadly for polar bears. As the pack ice melts sooner, farther and reappears later in the year, polar bears are often stranded on land for long periods, and left with fewer food options.
