CO2 ice core data

CO2 ice core data involves analyzing ancient air trapped in ice layers drilled from ice sheets. These layers preserve a record of Earth's atmospheric composition over thousands to hundreds of thousands of years. By measuring CO2 levels in these trapped air bubbles, scientists can track past climate changes and understand how atmospheric CO2 correlates with temperature, ice ages, and greenhouse effects. This information helps us see long-term trends and the impact of human activities on climate, providing critical context for current greenhouse gas increases and their role in global warming.
