Climate Modeling

Definition

Climate modeling is the scientific process of creating and using computer-based simulations to understand and predict the Earth's climate system and its changes over time. These models incorporate various physical processes, such as atmospheric dynamics, ocean currents, and greenhouse gas concentrations, allowing researchers to simulate past, present, and future climate scenarios.
