National Ice Core Lab stores samples from ice sheets all over the world

The National Ice Core Laboratory near Denver is...sorry...a really cool place. It's the repository for miles of ice that contains information about the planet's past and the history of its climate. Dick chatted with Richard Nunn, assistant curator of the lab, about what they do there, why it's important, and the special challenges involved with storing and studying ice. You can learn lots more about the lab at their website.
