I WONDER - Can Polar Ice Caps Tell Us Anything About History?

Ice cores are valuable for studying Earth's climate history. They contain layers of snow and ice that have trapped air bubbles over millennia, providing insights into past temperatures, greenhouse gas levels, and ecosystems. This data helps scientists understand natural climate variations and the effects of human activities on the planet.
