Antarctic ice cores reveal 800,000 years of climate data
Antarctic ice cores offer a frozen timeline of Earth's climate for 800,000 years, revealing past temperatures, CO2 levels, and the stark difference from today's human-driven changes.
Deep within Antarctic ice, scientists extract cores that act as frozen archives, preserving Earth's climate history from 800,000 years ago. These cores, like the groundbreaking one from EPICA, reveal dramatic temperature shifts, including ice ages 10 degrees Celsius cooler than today, driven by Earth's orbital changes. They show carbon dioxide levels fluctuating between 180 and 300 parts per million during these natural cycles.
