Climate modeling

Definition

Climate modeling is the use of mathematical representations of the Earth's climate system to simulate and predict future climate conditions based on various factors such as greenhouse gas emissions, solar radiation, and land use changes. These models help scientists understand past climate patterns and forecast future changes in weather and climate, making them essential tools for informing policy decisions and public awareness regarding climate issues.
