Climate change goals and actions are often discussed with reference to their feasibility. However, in the climate change literature, there is no agreed upon understanding of what feasibility means. In this paper, insights from political philosophy are used to address this problem in a two-fold way. First, different uses of the term feasibility in the climate change context are critically analyzed, surfacing problematic uses that can have severe consequences for what goals or actions are considered. Second, the ‘conditional probability account (...) of feasibility’ is presented as a positive account of how feasibility should be understood in the climate change context, and applied to the case of managed retreat as an approach for adaptation to sea level rise. Together, the critical analysis and the positive proposal furthers a necessary discussion on feasibility in the context of climate change. (shrink)
