Global warming driven by rising greenhouse gas concentrations is expected to cause sea level rise, intensify extreme precipitation, and alter storm characteristics. This project leverages high-resolution regional climate model simulations to assess the projected impacts of these changes on coastal cities. Specifically, it examines shifts in the frequency, intensity, and spatial distribution of extreme precipitation and sea level rise, accounting for the effects of ocean warming and land subsidence, as well as the clustering of storms under different greenhouse gas emission scenarios. The findings aim to enhance the understanding of climate change-driven risks in coastal regions, supporting the development of effective adaptation strategies and urban resilience planning.
