This Antarctic ice core has a 1.5 million-year-old story to tell

It came from 2.8km beneath the surface of the East Antarctic Peninsula. It’s the oldest ice ever recovered. Scientists believe its record of the distant past can help us plan for the future. It’s not the ice itself that keeps a record of the past, it’s the air bubbles trapped inside the core. Each bubble is a tiny sample of the atmosphere at the time it froze. As the ice melts, these bubbles release their secrets.
