A massive ice core from Antarctica’s Dome C provides a continuous record of Earth’s atmosphere over the last 800,000 years, revealing that current CO2 levels far exceed natural historical ranges. A new, deeper core has extended this timeline to 1.2 million years, offering unprecedented insights into ancient climate cycles.
Scientists have extracted data from Antarctic ice cores dating back 800,000 years, revealing insights into past climate, volcanic eruptions, and human activities. A recent study using ice cores showed the impact of European colonization on Indigenous populations, with the deaths of 56 million people leading to increased forest growth and reduced carbon dioxide levels. This demonstrates the significant influence of human actions on the Earth's atmosphere, highlighting the lasting effects of historical events on the planet.
