Natural Climate Change

The video explores Earth's climate history, focusing on ice ages and the detailed climate records stored in polar ice. Ice cores reveal past atmospheric conditions, showing natural cycles of warming and cooling. These cycles are influenced by factors like Earth's orbit and volcanic activity. However, current climate change is driven by human pollution, with a rapid increase in carbon dioxide levels. This unprecedented rate of change poses unknown risks to the planet's environment.

What is the significance of the recent rate of change in atmospheric carbon dioxide?
