Ice core records

Ice core records are cylinders of ice drilled from glaciers or ice sheets that contain trapped atmospheric gases, particles, and chemicals from thousands of years ago. As snow falls and compresses into ice, it preserves a historical record of Earth's climate, including temperature changes, volcanic eruptions, and greenhouse gas levels. By analyzing these layers, scientists can reconstruct past climate conditions and better understand how Earth's climate has evolved over millennia. Ice cores are vital tools for studying long-term climate variability and predicting future climate trends.
