Global Climate Model

A Global Climate Model (GCM) is a sophisticated computer simulation that scientists use to understand and predict the Earth's climate systems. It incorporates data about the atmosphere, oceans, land, and ice to replicate how these components interact and respond to factors like greenhouse gas emissions. By running these models, scientists can forecast future climate changes, such as temperature rises and weather pattern shifts, helping us prepare for and address global warming effects. GCMs are essential tools for informing environmental policy and understanding complex climate dynamics on a planetary scale.
