ABSTRACT. - The economic dimension of climate change. The acceptance of human agency for climate change by a scientific consensus, although controversial, could be interpreted as another step for strengthening the motivation for action at all levels. The paper argues that this motivation could be strengthened even more by revealing the economic dimension of climate change. In this framework, the paper aims to construct an economic argument for increasing the intensity climate change action. Milestones of climate change action and the rational for climate change cost estimates are firstly explored to set the framework of the main analysis. This then is focused on the predictions of different integrated assessment models in terms of GDP losses to be expected in different scenarios. By gathering the common characteristics of these outcomes there were found some economic reasons for more intense mitigation and adaptation actions.
Key words: climate change, climate change action, cost estimates, economic reason, integrated assessment
