Coastal Futures (CoFu) - An interactive viewer for 21st century projections of coastal climatic impact-drivers

The IPCC AR6 WGI assessment states with high confidence that all coastal climatic-impact drivers (CIDs) assessed therein (i.e. Relative sea level, coastal flood and coastal erosion) will increase by mid-century in almost all regions of the world. This means that adaptation is now urgently needed to mitigate or reduce the climate change induced risks for coastal communities and assets. While local scale adaptation measures need to be informed by detailed local scale impact and risk assessments, available global data sets of CIDs are very useful for identifying global or regional hotspots of potential impacts. However, these data sets are produced by different organizations around the world and presented in many different studies, thus it is cumbersome to compare and contrast different projections. As a solution, Coastal Futures (CoFu), an interactive online viewer (https://coastal-futures.org/) is developed by IHE Delft, which for the first time, combines several published state-of-the-art data sets of 21st century projections of CIDs, including those assessed in IPCC AR6 WGI, for different time periods and climate scenarios. CoFu enables coastal scientists, engineers, planners, managers and policy makers to quickly see how coastal CIDs are projected to change worldwide. In addition, this viewer enables the dissemination of most recent scientific knowledge on CID projections to not only many different stakeholders interested in coastal safety, coastal developments and adaptation, but also citizens and especially the young generation to promote environmental awareness and understanding for a sustainable future. CoFu will be continually updated by adding more datasets as they become available.
