National Public Radio and National Geographic are broadcasting a series on the impacts of climate change called Climate Connections. The series, part of Weekend Edition Sunday, looks at signs of climate change in the polar regions and other parts of the world, including sections on adaptations, causes of climate change, and profiles of people past and present who have been influential in studying the issues.

Recent stories have examined the impact of climate change on the Adelie penguins of Cape Royds,  “Penguins Helped and Hurt by Changing Climate,”  and the impact of the beauty of the southernmost continent on .recent visitors, “Antarctica’s March of the Tourists.”  For a journalist’s look at the U.S. research station at the South Pole, choose “A Bright Spot of Life on the Icy Continent” by Daniel Zwerdling. He’ll tell you about the dining hall windows that look out on the simple metal pole stuck in the snow , the well-equipped gym, and the greenhouse, but he also explains how the people who work there are “actually part of a giant geopolitical chess game.” Videos and slide shows accompany some of the articles. .

Articles are available as web pages, in audio, and as RSS feeds.
