Our Simulations

We are here to share accessible simulations to spark effective action that stabilizes the global climate.

Our primary simulation -- the one underneath most of our current work -- is the Climate Rapid Overview and Decision-support Simulator (C-ROADS). The online, 3-region version of C-ROADS is called C-Learn and is available here online.  And we also have a dynamic, Climate Momentum Simulation, based on multiple runs of our C-ROADS model.

Our latest simulation, En-ROADS, builds off the insights we gained while developing C-ROADS to examine how our choice of energy sources and policies can address climate change.

We have two much simpler animated simulations completed and available online -- the Climate Bathtub Animation and MIT's Greenhouse Gas Emissions Simulator.

Finally, we have our simulation-model-based "Mock-UN" policy exercise, World Climate (formerly the Copenhagen Climate Exercise).

En-ROADS

Our Energy Rapid Overview and Decision-Support (En-ROADS) simulator provides insight into how we can achieve our climate goals through changes in our energy use, consumption, and policies. En-ROADS focuses on how changes in global GDP, energy efficiency, R&D results, carbon price, fuel mix, and other factors will change carbon emissions and results such as temperature.

C-ROADS

The Climate Rapid Overview and Decision-support Simulator (C-ROADS) is a 7-20 region, policy-maker-oriented climate simulator that has undergone scientific review and is being used in support of international climate change negotiations.

Climate Momentum Sim

Our Climate Momentum Sim allows users to quickly compare the resulting sea level rise, temperature change, atmospheric CO2, and global CO2 emissions from six predetermined scenarios. This sim was designed by Drew Jones and Nicholas Owens of Booksmuggler using output from C-ROADS.

 

 

 

World Climate:  A Computer-Simulation-Based Role-Playing Exercise

World Climate, formerly the Copenhagen Climate Exercise is an interactive role-playing policy exercise where groups of 10-50 play the delegates of different countries from three major parts of the world and work to reach an agreement to stabilize the climate. A simplified version of C-ROADS calculates the effects of such agreements.

 

Climate Bathtub Animation

What happens if we cap global carbon dioxide emissions at current levels? Built with a team from Schlumberger, this animated simulation of the global carbon system is great for helping people explore the relationship between carbon emissions and atmospheric CO2. We also have an overview video and facilitator's guide.

 

 

 

MIT's Greenhouse Gas Emissions Simulator

Dr. John Sterman led the creation of this more advanced animated simulator that, like the one above, uses the bathtub metaphor but explores more factors and more complexity.
