As an AI language model, I don't have the most updated information on geological events, but as far as I know, the statement is generally true. Many coastlines worldwide are still adjusting to modern sea levels due to a combination of natural processes such as tectonic uplift or subsidence, as well as anthropogenic factors such as land-use changes and groundwater pumping. However, some coastal areas may have reached equilibrium with current sea levels, and others may experience temporary or permanent changes due to natural hazards like storms, tsunamis, or sea-level rise.
