Sea Level Rise in the U.S. | High-Tide Flooding in Annapolis & Coastal Cities

While sea level rise is often discussed as a future challenge, many U.S. communities are already feeling its effects today through high-tide flooding—also known as sunny day flooding or nuisance flooding. This occurs when slightly higher sea levels, caused by melting glaciers, ice sheets, and warming oceans, combine with high tides or offshore breezes to push water into coastal streets.

In this video, we explore Annapolis, Maryland—home of the U.S. Naval Academy—where flooding events have dramatically increased in recent years. Waters now breach flood walls or back up through storm sewers, impacting daily life in this historic city. With support from NOAA and NASA data, city engineers and Naval Academy teams are developing flood mitigation strategies to protect infrastructure and communities.

Annapolis is not alone. Major cities like Boston, New York, Philadelphia, Norfolk, Charleston, Savannah, and Miami are also facing the urgent reality of rising seas and planning for a more flood-prone future.

🔥 Watch how coastal communities are fighting back against climate change-driven sea level rise and protecting their future.
