Abstract: In this study we conducted a comprehensive modelling analysis to identify global trends in extreme Wave Energy Flux (WEF) along coastlines in the 21st century under a high emissions pathway (RCP8.5). For the end of the century, results show a significant increase up to 30% in 100-year return level WEF for the majority of the coastal areas of the Southern Temperate Zone, while in the Northern Hemisphere large coastal areas are characterized by a significant negative trend. We show that the most significant long term trends of extreme WEF can be explained by intensification of teleconnection patterns such as the Antarctic Oscillation (AAO), El-Nino Southern Oscillation (ENSO) and North Atlantic Oscillation (NAO). The projected changes will have broad implications for ocean engineering applications and disaster risk management. Especially low-lying coastal countries in the Southern Hemisphere will be particularly vulnerable due to the combined effects of projected Relative Sea Level Rise (RSLR) and more extreme wave activity.
