These photographs are from Paul Nicklen’s recently released book, Polar Obsession (National Geographic Focal Point, $50), the culmination of 15 years of work photographing wildlife in the arctic and Antarctica. The book celebrates the arctic and Antarctic ecosystems and discusses the urgent need to halt global warming, which threatens their existence.
