Ultimately, however, each country's action will depend upon its assessment of the relative costs and benefits of policy intervention. The results of EMF-12 were, therefore, not enough to offer complete insight into those judgments. Working with individuals involved in the development of climate policies and negotiations, participants ran mutually agreed-upon standardized scenarios so that key outputs could be compared. They then confronted a series of policy related problems employing scenarios of their own design. It was impossible for any group to complete every task.
Care needs to be taken in their interpretation.
They do not, however, reflect uncertainty. In addition, the EMF results are not all independent. It was, in fact, curious to note that early reports displayed wider dispersion across the standardized runs than the modeler's choice trajectories. References Alcamo, J., G.J.J. Kreileman, M.S.
