Climate Cycles

The video explores climate changes over thousands of years, focusing on data from Greenland's ice cores. These cores provide a detailed climate history, revealing both gradual and rapid shifts. By analyzing the chemical makeup of ice layers, scientists can determine past temperatures. A graph illustrates temperature changes over 50,000 years, highlighting a long Ice Age followed by warming. The video also discusses rapid climate changes within decades and questions the causes of these shifts.
