Ice cores allow scientists to investigate Earth's climate over the past 740,000 years. Ice cores are cylindrical samples of ice drilled from glaciers and ice sheets. They provide valuable information about past climate conditions by trapping air bubbles and various impurities within the ice layers. By analyzing the composition of these trapped materials, such as greenhouse gas concentrations and isotopes, scientists can reconstruct past climate changes, atmospheric conditions, and temperature variations, helping us understand the Earth's climate history.
I hope this helped!
