Scientists from the European Beyond Epica project have drilled an ice core of no less than 2,800 meters long at the South Pole. With the help of this, the global climate can be reconstructed up to at least 1.2 million years ago. "It is a historic moment for climate and environmental science."

An international team of scientists announced on Thursday that it had successfully drilled one of the oldest ice cores in Antarctica from a depth of almost three kilometres, thought to have formed at least 1.2 million years ago. The analysis of ancient ice is intended to show how Earth's atmosphere and climate evolved.
