Concurrent heatwaves and sea level rises happening more at coastal locations, PolyU study finds

A research conducted by Dr WANG Shuo, Member of the Research Institute for Land and Space (RILS), the Research Institute for Sustainable Urban Development (RISUD) and the Otto Poon Charitable Foundation Smart Cities Research Institute (SCRI), Associate Professor in the Department of Land Surveying and Geo-Informatics (LSGI), and his team has found that the concurrent occurrence of heatwaves and extreme short-term sea level rises at coastal locations significantly increased between 1998 and 2017 when compared to the preceding 20 years. The study also predicted that, under a modelled high emissions scenario, the probability of the occurrence of such events in 2025–2049 may multiply by fivefold. The research findings provide scientific evidence and guidance for improving climate adaptation strategies in response to extreme weather events, which will aid in the development of climate-resilient coastal cities. The study has been published in the journal Communications Earth & Environment.
