DR. PAUL MAYEWSKI, chief scientist with the Greenland Ice Sheet Project 2. The project archives tubes of ice extracted from Greenland which chronicle 250,000 years of the earth's atmosphere, and changes in the climate. From the ice, scientists can pinpoint the start of the industrial revolution, or the end of the ice age. Scientists hope, by looking at the ice, they can better understand rapid changes in the earth's climate
