International Polar Bear Day
A polar bear's life cycle is closely tied to sea ice. Polar bears live on sea ice throughout the Arctic for most of the year. They return to land if forced to by melting ice in summer, or to deliver their cubs.
As the climate warms, sea ice is melting earlier and forming later, reducing the amount of time that polar bears (Ursus maritimus) have access to their main food source: seals.
