The document presents a model of the climatic system that shows the interactions between the atmosphere, ocean, ice, land, and human activity. It also distinguishes between the external inputs and outputs to the Earth-atmosphere system and the internal interactions within the system. The model is used to represent the complex relationships and feedbacks between different components that influence the climate.
