Global Relationship Assessment to Protect the Environment (GRAPE)

From Open Energy Information

A model consisting of five modules dealing with issues on energy, climate, land use, macroeconomics and environmental impacts. The model uses a nonlinear dynamic intertemporal optimization methodology maximizing regional utilities, which are functions of macroeconomic consumption and population.

Emissions or radiative forcing data are given to obtain global average surface atmospheric temperature change and sea level rise. Model accounts for anthropogenic greenhouse gas emissions, cumulative emissions, atmospheric greenhouse gas concentrations, temperature rise (global mean surface air temperature), and sea level rise by thermal expansion.
