A European research team has achieved a breakthrough in climate science by drilling an ice core in Antarctica that extends back at least 1.2 million years. The core, 2.8 kilometers long, is expected to provide crucial insights into the Earth’s climatic history, particularly in understanding the transitions between warm and ice ages. This historic project, part of the EU-funded ‘Beyond EPICA – Oldest Ice,’ brings together international scientists and aims to solve one of the biggest mysteries in climate science regarding ice age cycles.
