The launch version of the Climate Collaboratorium uses a single climate model, C-LEARN.
C-LEARN is a Web-based version of C-ROADS, a simulation of Sustainability Institute and Ventana Systems that is part of the Climate Interactive effort.
The model's inputs are:
- Targets for greenhouse gas emission reduction
 - Targets for reductions in deforestation and increases in aforestation
 
Its outputs are:
- Atmospheric concentration of carbon dioxide (CO2)
 - Increase in global mean temperature (GMT) above baseline year
 
This writeup about C-LEARN contains three primary sections
- C-LEARN overview
High level description of the model; information about its developers and their institutional affiliation; the model's history and how it can be accessed; documentation and key publications. 
- C-LEARN attributes
The model's geographic scope and resolution; its start date, end date, and time step; its data sources; its approach for dealing with uncertainty; and its overall structure.
