Some of the oldest ice ever recovered from Antarctica has arrived in the UK for climate analysis, more than a million years after it captured some of the Earth's atmosphere at the time.
Breakdown
- Ancient Antarctic ice cores, over 1.5 million years old, have arrived in the UK for study. 6s
- The ice was drilled from 1.7 miles deep in the East Antarctic Peninsula and shipped to Europe. 35s
- These samples could nearly double the existing ice core climate record to 1.5 million years. 49s
- Researchers aim to understand shifts in Earth's glacial-interglacial cycles and their link to CO2 levels. 57s
- Analysis of trapped air bubbles will provide the first continuous environmental reconstructions over this period. 1m 27s
