International Polar Bear Day

International Polar Bear Day is an annual event celebrated every February 27 by Polar Bears International. One of the aims of International Polar Bear Day is to raise awareness about the conservation status of the polar bear and raise awareness about the impact of global warming and reduced sea ice on polar bear populations.

The polar bear (Ursus maritimus) is a carnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is a large bear, approximately the same size as the omnivorous Kodiak bear (Ursus arctos middendorffi) A boar (adult male) weighs around 350–700 kg (772–1,543 lb), while a sow (adult female) is about half that size. Although it is the sister species of the brown bear, it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice and open water, and for hunting seals, which make up most of its diet. Although most polar bears are born on land, they spend most of their time on the sea ice. Their scientific name means “maritime bear” and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. Because of their dependence on the sea ice, polar bears are classified as marine mammals.

Climate change has effected the Polar bear greatly with a rise in temperature melting the ice on which the Polar Bear depends for hunting. Consequently this has resulted in habitat loss and the polar bear is classified as a vulnerable species, with at least three of the nineteen polar bear subpopulations currently in decline. However, at least two of the nineteen subpopulations are currently increasing, while another six are considered stable. For decades, large-scale hunting raised international concern for the future of the species, but populations rebounded after controls and quotas began to take effect. For thousands of years, the polar bear has been a key figure in the material, spiritual, and cultural life of circumpolar peoples, and polar bears remain important in their cultures. Historically, the polar bear has also been known as the white bear.

Another aim of International Polar Bear day is to encourage people to find ways to reduce their carbon output, such as by turning down their thermostat or driving less. The day has also been used to encourage the installation of energy efficient insulation in houses. Many zoos also use the day to educate about polar bear conservation and to encourage visitation to polar bear exhibits. It has also had some political impact. Jack Shapiro, the deputy climate campaign manager under American president Barack Obama, used the day to argue for the need for Congressional action on the issue of climate change. The University of Saskatchewan announced in 2014 that it would be turning its thermostats up two degrees in the summer and down two degrees Celsius in the winter to honor International Polar Bear Day. The decision is expected to reduce the university’s carbon emissions by two-thousand tons and save the university over two-hundred thousand dollars per year.
