Arctic ice loss forces polar bears to use four times as much energy to survive – study

Polar bears and narwhals are using up to four times as much energy to survive because of major ice loss in the Arctic, according to scientists. Once perfectly evolved for polar life, apex predators are struggling as their habitats shrink and unique adaptations become less suited to an increasingly ice-free Arctic, researchers say. The mammals […]

Listening to marine mammals is helping scientists understand Arctic impacts of climate change

A 4-year bioacoustic study of marine mammals in the northern Bering Sea will help scientists track the impacts of global climate change on Arctic ecosystems. Researchers with WCS (Wildlife Conservation Society), Columbia University, Southall Environmental Associates, and the University of Washington wanted to understand how seasonal variation in sea surface temperatures and sea ice affect […]
