This article describes a new method of studying climate change. A previously unnoticed cooling trend that persisted for a millennium caused enough ice to build up in Antarctica's Ross Sea that thousands of Adelie penguins abandoned their colonies beginning about 2,000 years ago. The techniques may also help to refine our understanding of climatic change on the southernmost continent. This article is enhanced by a video and photographs and the site offers links to more information including a version of the original paper.
