A frozen lake in the Arctic Circle is telling us how sensitive the poles are to climate change. Producer Moira Rankin takes us to Lake El'gygytgyn and reports on the 3.6 million year record of climate change that scientists have unearthed from the lake's bottom. Chief scientist Julie Brigham-Grette from the University of Massachusetts details her findings that the slightest change in climate produces significant changes in the environment.
