The decline of summer sea ice has dramatically changed the face of global commerce and trade in the Arctic and the increase in industrialization and shipping traffic has the potential to significantly impact the Bering Strait and its inhabitants. WWF is working with researchers to track polar bears in the Arctic to understand the impact that climate change and other threats are having on them as well as helping to monitor their health. Contact with oil spills can reduce the insulating effect of a bear’s fur requiring them to use more energy to get warm, and can poison them if ingested.

We advocate for governments to recognize and mitigate the effects of climate change on polar bears. We’re also advocating for governments to recognise and mitigate the effects of a changing Arctic on these bears.

In the Arctic, most industrial development has been on relatively small pieces of land.

Terrestrial and marine denning habitats for polar bears are increasingly disappearing and under threat from climate change and human and industrial influence. Although most of the world's 19 populations have returned to healthy numbers, there are differences between them. WWF encourages the use of Traditional Ecological Knowledge (TEK) to inform management policies in the Arctic.

This needs to be addressed immediately if polar bears and other species unique to the region are to survive. Support WWF with a monthly gift to help protect polar bears and other species.
