This two-minute sound segment discusses the future of the polar ice cap. The melting of the ice cap not only would affect the animals that live there but the open water created could speed up global warming and alter both global transportation and politics. This site is from an archive of a daily radio program called Pulse of the Planet, which provides its listeners with a portrait of Planet Earth, tracking the rhythms of nature, culture and science worldwide and blending interviews and extraordinary natural sound. The site also provides a written transcript of the broadcast.
