Earth's polar regions may seem remote, but they are an integral part of the entire Earth system. For example, pollution from other areas affects Arctic and Antarctic ecosystems, and changes in the icy landscapes of the polar regions may influence global ocean circulation patterns and accelerate climate change. The fourth International Polar Year (IPY) was a 2007–2008 international campaign to advance polar science and better understand global climate change through an interdisciplinary approach. Learn about the importance of studying the poles through these media resources, adapted from a variety of sources. Explore the polar regions, the changes they are experiencing, and their connections to the rest of the world.
