<human>:  What are the impacts of climate change on seawater levels?
<bot>: The impacts of climate change on seawater levels are wide ranging, including an increase in the frequency of storms and coastal flooding, vanishing coastlines, as well as increases in sea surface temperatures, ocean acidification, water salinization, and sea level rise. Additionally, climate change has led to enhanced coastal erosion, an increase in harmful algal blooms, and changes to marine ecosystems.
