Testing the Ice
An ice core is a core sample that is typically removed from an ice sheet, most commonly from the polar ice caps of Antarctica, Greenland or from high mountain glaciers. "Ice cores are one of the most effective, though not the only, methods of recreating long term records of temperature and atmospheric gases.Ice core records allow us to generate continuous reconstructions of past climate, going back at least 800,000 years." The basics of understanding the use of ice cores as a means to study climate change can be better understood at the web site Arctic Glaciers.
