Future Retreat of Arctic Sea Ice Will Lower Polar Bear Populations and Limit Their Distribution
Source: U.S. Geological Survey
Future reduction of sea ice in the Arctic could result in a loss of 2/3 of the world’s polar bear population within 50 years according to a series of studies released today by the U.S. Geological Survey.
Last December, Secretary of the Interior Dirk Kempthorne announced that the U.S. Fish and Wildlife Service (Service) was proposing to list the polar bear as a threatened species under the Endangered Species Act. In January 2008, following a one-year review period, the Service is expected to make a recommendation to Secretary Kempthorne on whether or not to list the polar bear as threatened. To assist the Service in making that recommendation, Secretary Kempthorne requested USGS leadership in studies to inform the Service’s deliberations on polar bear status. This information summarizes and integrates the results from a series of studies on polar bear populations, range-wide habitats and changing sea ice conditions in the Arctic.
