One of the latest new directions in futures studies is interactive simulation modeling. This type of modeling is able to create complex alternatives for the future. This methodological research trend entirely fits this study. It shows how the interactive climate model is scientifically developed. Using the Java Climate Model, it is possible to display the social and the economic consequences of climate change. Using this model, analyses of comparative climate change scenarios can show the possible effects of economic policy on the environment in the short and long term. It also provides data on various regional levels. This study shows two possible non-extreme alternative scenarios for the European continent’s economy and climate, and their consequences. A study has been done by the author recently, showing two extreme alternatives, focusing on the best and worst options, respectively. These new alternatives presenting in this study, however, give realistic options for professionals.
