Greenland ice core

Greenland ice cores are long cylinders of ice drilled from the Greenland ice sheet, containing layers that record past climate conditions over thousands of years. As snow falls and compacts into ice, it trapping air bubbles and particles that reveal information about ancient temperatures, atmospheric gases, and greenhouse gases like carbon dioxide. By analyzing these layers, scientists can reconstruct Earth's climate history, helping us understand natural climate variations and the impact of human activities. Greenland ice cores are valuable for studying how our climate has changed over time and predicting future trends.
