The video explores how ice cores from Greenland provide insights into Earth's climate history. By analyzing layers of ice, scientists can determine past temperatures and identify events like volcanic eruptions and industrial activities. The data reveals that while climate changes can occur over thousands of years, there are also rapid shifts within decades. This understanding helps reconstruct the climate of the past 50,000 years, showing long ice ages and sudden warming periods.
