The Full Story
In 2004, scientists reported the EPICA Dome C ice core from Antarctica, which extended climate records back about 800,000 years. This was a major leap beyond the previous longest records and helped scientists study repeated ice-age cycles. The core trapped ancient air and revealed how temperature and greenhouse gases changed together. It remains one of the most important climate archives ever recovered.
