This newly extracted ice preserved a record of our planet’s climate history, continuous information on atmospheric temperatures, and some clear samples of old air with greenhouse gases. “This is the longest continuous record of our past climate from an ice core,

An international team of scientists say they’ve successfully drilled one of the oldest ice cores yet, penetrating nearly 2 miles to Antarctic bedrock to reach ice that's at least 1.2 million years old

Antarctic ice, however, has been at it for over a million. An international team of scientists has extracted a 1.74-mile-long (2.8 kilometers) ice core in Antarctica, hitting the frozen continent’s bedrock.

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