Vostok Ice Core

The Vostok Ice Core refers to a long cylinder of ice extracted from beneath Antarctica's Vostok Station. This ice contains trapped air bubbles and layers that hold clues about Earth's past climate, going back over 400,000 years. By analyzing the composition of these bubbles, scientists can learn about historical greenhouse gas levels, temperature changes, and atmospheric conditions. This research helps us understand natural climate cycles and the effects of human activity on global warming, providing valuable insights into climate change and helping inform future environmental policies.
