We advocate for governments to recognize and mitigate the effects of climate change on polar bears.

At the same time, the retreating ice is resulting in more polar bears spending longer periods on land. Offshore petroleum installations and operations in the Arctic are expected to increase in number. This expansion would likely affect polar bears and their habitat in many ways, including the following: In the Arctic, most industrial development has been on relatively small pieces of land. As summer sea ice retreats, a new ocean is emerging, which allows more opportunities for industrial development at sea and on larger parcels of land, which WWF is currently fighting against.Polar bears rely heavily on sea ice for traveling, hunting, resting, mating and, in some areas, maternal dens. But because of ongoing and potential loss of their sea ice habitat resulting from climate change–the primary threat to polar bears Arctic-wide–polar bears were listed as a threatened species in the US under the Endangered Species Act in May 2008. As their sea ice habitat recedes earlier in the spring and forms later in the fall, polar bears are increasingly spending longer periods on land, where they are often attracted to areas where humans live. The largest bear in the world and the Arctic's top predator, polar bears are a powerful symbol of the strength and endurance of the Arctic. The polar bear's Latin name, Ursus maritimus, means "sea bear." It's an apt name for this majestic species, which spends much of its life in, around, or on the ocean–predominantly on the sea ice. In the United States, Alaska is home to two polar bear subpopulations. Due to climate change the Arctic is heating up twice as fast as anywhere else on the planet, shrinking the Arctic sea ice cover by 14% per decade. Compared to the median sea ice cover recorded between 1981-2010, we have lost about 770,000 square miles, an area larger than Alaska and California combined. These measures must be based on identified Indigenous marine use in the Bering Strait. Now is the opportunity to protect this new maritime frontier before it is too late. Bilateral cooperation will be essential for the success of these recommendations.

We've supported the design of steel food storage containers, so that local people can continue to store their food outside but protect it from marauding bears and electric fences to separate bears from dog teams. Keeping polar bears separate from people is better for both, since polar bears that wander into communities pose a risk to people, and people often respond by killing the bears. WWF has responded with a variety of locally-led initiatives to help reduce conflict. Throughout the Arctic, we convene workshops for people to share their experiences and successes in keeping the peace between people and bears. WWF's goal is to ensure that wherever industrial development takes place, it is sustainable and does not damage wildlife populations and ecosystems to any great extent. We offer technical expertise on oil spill prevention and response. We also advocate for the highest development standards through national and international venues. We support research on climate change effects, and show the way forward by funding research and analysis on alternative energy.

Polar bears spend over 50% of their time hunting for food. A polar bear might catch only one or two out of 10 seals it hunts, depending on the time of year and other variables. Their diet mainly consists of ringed and bearded seals because they need large amounts of fat to survive. WWF has a dedicated worldwide team working on issues of climate and energy, working regionally, nationally, and internationally.
