This Is the Oldest Ice on the Planet and It’s About to Be Slowly Melted to Unlock 1.5 Million Years of Climate History
EAST ANTARCTICA, JUL 18 – Researchers from 10 European nations analyze 1.5 million-year-old ice core to study the Mid-Pleistocene Transition, revealing past climate shifts and aiding future climate predictions.
- Recently, scientists at the British Antarctic Survey in Cambridge began gradually melting a 1.5-million-year-old Antarctic ice core, now analyzing it to unlock Earth's ancient climate secrets.
- Scientists aim to resolve how the Mid-Pleistocene Transition shifted glacial-interglacial cycles from 41,000 to 100,000 years, improving climate predictions.
- Using continuous flow analysis to measure chemical elements, particles, and isotopes during melting, revealing Earth's past climate conditions.
- Dr. Liz Thomas told the BBC, 'Our climate system has been through so many different changes,' while James Veale described it as an 'amazing feeling,' knowing it held secrets from a time before humans, the team comprises researchers from 10 European nations.
- Researchers anticipate that the ice materials hold clues about ancient climate and atmospheric composition, enabling reconstruction of wind patterns, temperatures, and sea levels up to 1.5 million years ago.

In Cambridge, the "world's oldest ice" from Antarctica is ready for analysis. The ice cores may be 1.5 million years old, or even older. Scientists are very curious about the results, because the ice could teach us new things about the climate a million years ago. Even then, CO2 levels in the atmosphere were quite high.
Science breakthrough as Antarctic mystery unlocked after melting of rare 1.5 million-year-old ice
British scientists are set to melt a very rare 1.5million year old ice cylinder from the Antarctic ice sheet.Researchers at the British Antarctic Survey in Cambridge received the extraordinary cylinder with it being brought to the UK for analysis."This is a completely unknown period of our Earth's history," explained Dr Liz Thomas, who leads ice core research at the institution.The pristine samples arrived in specially refrigerated containers fo…
