Led by The Institute of Polar Sciences of the National Research Council of Italy (ISP-CNR), the scientists worked for more than 200 days, drilling into the ice and processing the ice core at a remote site in East Antarctica called Little Dome C, with a balmy average summer temperature of -31 degrees Fahrenheit (-35 degrees Celsius).

Scientists have drilled a deep hole in the Antarctic bedrock that may hold information that dates back more than a million years.

The fourth Antarctic campaign of the “Beyond EPICA - Oldest Ice” project, funded by the European Commission, has achieved a historic milestone for climate science. An international team of scientists successfully drilled a 2,

Dorthe Dahl-Jensen, a researcher from the University of Manitoba, was part of a team that successfully drilled into an ice core 2,800 metres in length, and uncovered the oldest ice core ever retrieved - more than 1.2 million years old. She said the core will give an insight into past climate patterns.

A team of scientists have drilled one of the oldest ice cores yet, penetrating nearly 2 miles to Antarctic bedrock to reach ice that 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. Scientists say it should provide insight into how Ice Age cycles have changed, and may help in understanding how atmospheric carbon changed climate.
