Quizplus · Accepted Answer

This is true. A general circulation model (GCM) is a type of computer model that simulates the Earth's climate system by linking the physical, chemical, and biological processes of the atmosphere, oceans, land surface, and ice. GCMs are used to study past and present climates, and to make projections of future climate change under different scenarios of greenhouse gas emissions and other factors.
