Abstract: Climate-related extreme events such as Hurricane Katrina (2005) or Maria (2017); Superstorm Sandy (2012), extreme precipitation or heat waves have directly hit many ports around the world in recent years. Ports are becoming increasingly aware of the risks of climate change, partly because of these events. However, very few are taking adaptation into practice, often due to the lack of information and the high uncertainties associated with climate change. This paper presents a multi-level methodology for conducting climate change risk assessment in existing ports following a sequential path that starts with a quantitative analysis focused on multi-hazard and multi-impact evaluation with climate information based on indicators. If needed the first level will be combined with a qualitative analysis based on perceived risk of stakeholders in order to determine the necessity of carrying out a high-resolution analysis, increasing the quantity, quality and resolution of input data, climate information and impact modelling aiming at reducing uncertainties. Results provide port managers with essential information to identify hot spots and prioritize adaptation strategies.
