Rationale behind use of simulation models#

There are many uncertainties about how the physical, economic, and social systems related to climate change work.

But today's computer simulation models can make informed projections of the impacts many of our actions might have.

These models are certainly not perfect, but taking into account what they can tell can impose discipline on our thinking as we consider the advantages and disadvantages of various actions.

Models in the Climate CoLab#

In the 2010 and 2011 global contests, the actions specified in proposals were translated into model inputs.

The models in the Climate CoLab then projected the impacts that would result if the proposed actions were taken.

A model was automatically included in all global proposals in the Climate CoLab.

The 2010 and 2011 global contests rely on the MIT Composite Model, and it is anticipated that global contests for 2012 will do the same.

The models in the Climate CoLab make it easy for people with no specialized background to specify actions (such as percentage reductions in carbon emissions) and see the projected impacts of these actions (such as changes in temperature and sea level).

Extending existing models and adding new ones#

Members who want to are also encouraged to submit extensions to the models already included in the CoLab and even to submit entirely new models.

Submitted extensions and new models will be reviewed by the CoLab staff and expert advisors and, if appropriate, added to the site where all members can use them.

For now, if you have ideas for extensions of existing models or new models to add to the Climate CoLab, please send a message to Robert Laubacher.
