High Tide Flooding

The video discusses the increasing problem of sea level rise, highlighting its causes, such as ice melt and thermal expansion due to global warming. It explains the impacts on US coastlines, including more frequent flooding and economic consequences. The video also covers variability in sea levels due to seasonal cycles and events like El Nino. Current impacts on communities are detailed, with examples of infrastructure challenges. Finally, it presents strategies for mitigation and adaptation, such as backflow preventers and increasing green spaces, emphasizing the need for data-driven decision-making.
