The long-time representatives of the Arctic, polar bears (Ursus maritimus), are facing some of the biggest challenges brought about by global warming and climate change.
Polar regions are warming at a rate almost twice the global average, and the effects of this shift is heavily felt by polar bears whom rely on the sea ice for their survival. Polar bears have been in the Arctic for many years which has allowed them to adapt and thrive in cold temperatures.
Arctic changes will affect virtually every aspect of the polar bear's existence. For example, delayed ice formation and earlier melting will shorten the bear's hunting season, which will cause reduced fat stores, deteriorated body condition, and a reduced survival and reproduction rate.
Ultimately, all of these effects will result in a greater incidence of polar bear starvation. As more of the Arctic becomes accessible to humans, the frequency of contact between humans and bears will increase, leading to a greater likelihood of harmful contact.
