A team of U.S. scientists has discovered the oldest directly dated ice and air on the planet in the Allan Hills region of East Antarctica.
The 6-million-year-old ice and the tiny air bubbles trapped inside it provide an unprecedented window into Earth’s past climate, according to a new study published today in the Proceedings of the National Academy of Sciences.
The oldest ice sample from Allan Hills dated by researchers clocks in at 6 million years, from a period in Earth’s history where abundant geological evidence indicates much warmer temperatures and higher sea levels compared to today.
