Ice Cores
Ice cores are cylindrical samples taken from ice sheets and glaciers, primarily in polar regions. As snow compresses over time, it traps air bubbles and other materials, creating layers that record climate history. Scientists analyze these layers to study past temperatures, atmospheric composition, and even volcanic eruptions, revealing insights into Earth's climate over thousands of years. By examining ice cores, researchers can better understand natural climate variations and human impacts, aiding in predictions about future climate change. This research is vital for developing strategies to combat global warming and protecting our environment.

Ice cores are cylindrical samples taken from ice sheets and glaciers, which trap layers of snow and ice that have accumulated over thousands of years. As each layer forms, it captures air bubbles, dust, and other particles, providing a historical record of Earth's climate. Scientists analyze these cores to study past temperatures, atmospheric composition, and environmental conditions, helping us understand climate change and its impacts. By examining the trapped gas concentrations and layers, researchers can also gain insights into historical events and natural processes over millennia.
