MAGICC stands for ‘Model for the Assessment of Greenhouse Gas Induced Climate Change’. It is a prime reduced-complexity model, often used by the Intergovernmental Panel on Climate Change (IPCC), for key scientific publications and by a number of Integrated Assessment Models.

MAGICC stands for ‘Model for the Assessment of Greenhouse Gas Induced Climate Change’. It is a prime reduced-complexity model, often used by the Intergovernmental Panel on Climate Change (IPCC), for key scientific publications and by a number of Integrated Assessment Models.

MAGICC has a hemispherically averaged upwelling-diffusion ocean coupled to an atmosphere layer and a globally averaged carbon cycle model. As with most other simple models, MAGICC evolved from a simple global average energy-balance equation.
