Make a Difference. We’re dedicated to conserving polar bears and the sea ice they depend on. Through media, science, and advocacy, we work to inspire people to care about the Arctic, the threats to its future, and the connection between this remote region and our global climate.

In 2008, the polar bear became the first vertebrate species to be listed under the U.S. Endangered Species Act as threatened due to predicted climate change. The Secretary of Interior listed the polar bear as threatened but restricted the Endangered Species Act's protections, and thus the polar bear's future is still very much in jeopardy.
