This paper uses a dynamic simulation model to situate the role of variables representing environmental processes in the social construction of the issues of climate change and global warming. In effect, it presents a quantitative dynamic simulation model of the social construction of a quasi-reality. By quasi-reality we mean a reality that thus far is defined by expert knowledge and is surrounded by uncertainty. A description of the model is followed by a demonstration employing a series of climate scenarios. Clearly there are many potentially serious limitations to the approach we have developed here, including the legitimacy of the postulates and the difficulty of acquiring suitable data for future calibration. However, in the broader context of promoting interdisciplinary efforts (necessary for increasingly geo-physical societal complexities), we hope, none the less, to have offered a demonstration of developing methodological possibilities.
