Jäätikköytimiä
Jäätikköytimiä, or ice cores, are long, cylindrical samples of ice drilled from glaciers and ice sheets. They are invaluable tools for understanding past climate and environmental conditions. These cores contain trapped air bubbles, dust particles, volcanic ash, and other impurities that act as a historical record of Earth's atmosphere and environment over hundreds of thousands of years.
The process of drilling ice cores is highly specialized, often taking place in remote polar regions. Special
Scientists analyze the composition of the ice and the trapped substances to reconstruct past temperatures, atmospheric
Ice core data has provided crucial evidence for climate change, demonstrating the strong correlation between greenhouse
