Coastal Flooding and Climate Change

The video discusses the impact of Hurricane Irene and Hurricane Sandy on New York Harbor, highlighting the significant increase in storm surge levels. It addresses the economic constraints in building higher protective walls and the importance of managing risk based on historical data. The video also notes the recent severe flooding events in New York City and the rising sea levels over the past century. It emphasizes the need to reevaluate shore protection due to climate change models predicting more extreme weather events and increased coastal flooding.
