Future changes in seasonal sea-level variability could reshape coastal ecosystems

Nature Climate Change, Published online: 13 May 2026; doi:10.1038/s41558-026-02631-yAssessments of coastal ecosystem resilience typically consider the impacts of annual mean sea-level rise, while increases in the seasonal sea-level cycle could also affect intertidal ecosystems. The authors show how such increases can threaten intertidal zones through altering the frequency and duration of inundation and emergence events.
