Scientists use computer programs called climate models to understand how our planet is changing. Climate models are simulations, a way for us to understand something that would be difficult to experience in real life. For example, the average person isn’t allowed to drive a race car. However, simulations—like video games—can help you experience what it would be like to zoom around a racetrack.
