Reducing Greenhouse Gases - How Do We Know?

The video discusses the process of testing climate models by comparing their predictions with past climate changes, particularly using paleo climate records. It highlights the challenges of ensuring models accurately reflect real-world data and emphasizes the importance of refining models to improve future climate predictions. Observations from the tropical Pacific region are used as a case study to illustrate these points. The video concludes by explaining how past data is crucial for refining models to predict future climate changes accurately.
