A global group of researchers has announced the successful drilling of one of the oldest ice cores recorded, reaching almost 2 miles deep into the Antarctic bedrock to access ice that is estimated to be at least 1.2 million years old.
On Thursday, a global group of researchers revealed that they have successfully extracted one of the oldest ice cores to date, drilling nearly 2 miles (2.8 kilometers) down to the bedrock of Antarctica to obtain ice that they claim is at least 1.2 million years old.
Analysis of the ancient ice is expected to show how Earth's atmosphere and climate have evolved. That should provide insight into how Ice Age cycles have changed, and may help in understanding how atmospheric carbon changed climate, they said.
