C-Learn

Use C-Learn here!

C-Learn is the 3-region, simplified version of the C-ROADS simulator. Designed for climate communicators, educators, and leaders of the Copenhagen Climate Exercise, the primary purpose of C-Learn is to help users understand the long-term climate effects (CO2 concentrations, global temperature, sea level rise) of various customized actions to reduce fossil fuel CO2 emissions, reduce deforestation, and grow more trees. You can ask multiple, customized "what if" questions and understand why the system reacts as it does. 

For information on the assumptions in the simulation, the testing of the simulation, and other technical specs, review the technical information on C-ROADS (of which C-Learn is a derivative -- the carbon cycle, forests, and climate sectors are identical).

Note: C-Learn does not meet other goals of C-ROADS such as analyzing specific proposals in the UNFCCC process.

C-Learn comes in two forms -- a version in Vensim software and a freeware version available online via Forio Business Simulations.  The Forio version will allow you to create your own "what if" graphs and understand why the system is doing what it is doing.

We are using C-Learn with partners such as the Climate Action Initiative.

Our plan is to share the equations to C-Learn, share the Vensim version with a General Public License (GPL), and share the code to the interface of the Forio version.
