Science Daily — In the wake of the U.S. government’s watershed decision to propose listing the polar bear as “Threatened” under the Endangered Species Act, the Wildlife Conservation Society (WCS) is launching a bold initiative to save the Earth’s largest terrestrial predator, not by following the bears themselves, but the receding sea ice habitat that may drastically shrink as a result of global warming. In a project named “Warm Waters for Cool Bears,” WCS will use both current and historical satellite imagery to predict where sea ice is likely to persist and where subsequent conservation efforts to save the species will be most effective.
