Antarctica holds a frozen archive of Earth’s climate history, with ice cores recording greenhouse gases and temperatures across thousands of years. Scientists drill deep into this ice, sometimes extracting air that is over 15,000 years old, to study the relationship between rising temperatures and greenhouse gases. Even the most advanced labs rely on these untouched samples to unlock insights into our planet’s future. The work is urgent, as understanding these patterns could shape how billions experience the effects of a changing climate.
