Integrated Assesment Models

Integrated Assesment Models are multi-disciplinary economic models which often integrate climate change with changes in non-renewable resources, demography, etc.

Model Description Source code How-to
Dynamic Integrated Climate Economy model Prize-winning economic model used to estimate the costs of human-indunced climate change on the global economy. Learn more… GAMS Guide
Global Change Analysis Model Open-source integrated assessment model used to generate scenarios for IPCC assessments. C++ (ECL-2.0) Not yet
World3 Legacy model model of non-renewable resource use and population growth, developed in the 70s until 2004, and still often cited in research today. Stella Not yet

Reduced Complexity Climate Models

Climate models take emissions of greenhouse gases and output greenhouse gas concentrations, radiative forcing and temperature change.

Model Description Source code How-to
OSCAR Simplified and fast constant time step model including modules for oceanic and terrestrial carbon cycles, and calibrated with CMIP. Python (CeCILL-2.1) Guide
Finite Amplitude Impulse-Response simple climate-carbon-cycle model Another simplified and near-instant climate change model. Python (Apache-2.0) Soon
The Hector Simple Climate Model Slightly more complex model with variable time step solver, more suited for highly non-linear behaviors. C++ (GPLv3) Soon
