The aim of this study is to measure the effects of the global warming in the cities in Turkey. The results of the global warming such as drought, temperature changes and rainfall changes are considered as criteria and the evaluation of the impacts of global warming in the cities in Turkey is handled as a multi-criteria decision-making model. A hybrid method considering fuzzy analytic hierarchy process and fuzzy measure theory is proposed to determine the corresponding degree of effect. Finally, considering real data, the map of effect with respect to the cities is presented. According to the results, the city that is most affected from the global warming is determined as Kutahya City in Turkey.
