Ice core data

Ice core data is collected from ice layers in glaciers and ice sheets, which preserve historical climate information. When scientists drill into ice, they pull out long cylinders (cores) that contain trapped air bubbles and layers of snow from different years. Each layer acts like a time capsule, revealing past temperatures, atmospheric gases, and volcanic activity. By studying these cores, researchers can understand how Earth’s climate has changed over thousands of years, helping to predict future climate patterns and assess human impact on global warming.
