Antarctic Ice Core Reveals Ancient Climate Secrets | Auckland News

Scientists just drilled a 200-meter sediment core from under Antarctic ice — a record-breaking feat after failed attempts — to unlock secrets of the West Antarctic Ice Sheet’s past behavior during warmer climates. This geological time capsule, retrieved from Crary Ice Rise, holds layers revealing when ice covered the land and when it was ocean, offering clues on how sensitive Antarctica’s ice is to warming. By analyzing ancient diatoms and fossil records, researchers date layers up to 19 million years old, when Earth was significantly hotter. While not covering recent warm periods, this data helps predict future sea level rise. The ultimate goal? To understand how to stop global warming before it’s too late.
