Antarctic Ice Core

Antarctic ice cores are long cylinders of ice drilled from ice sheets in Antarctica, containing layers that have accumulated over thousands of years. These layers trap tiny bubbles of ancient atmosphere, allowing scientists to analyze past climates, greenhouse gases, and temperature changes. By examining the chemical composition, dust, and isotopes within the ice, researchers can reconstruct Earth's climate history with high precision. Ice cores provide valuable insights into natural climate variability and help us understand how human activities are impacting our planet today.
