What Is a Climate Model and How Does It Work?

Union of Concerned Scientists

Climate models are the main tool climate scientists use to predict how Earth will respond to more heat-trapping pollutants in the atmosphere. Just by looking at the name, you can see that a GCM is a model that simulates the circulation of Earths different physical systems like the atmosphere and ocean. What causes a circulation?
