The east coast of United States is at high risk because of the presence of barrier islands, low elevation lands and gentle slopes of the coast.
The west Antarctic Ice sheet is collapsing at a faster rate due to the effect of Global Warming. This causes the ice to melt and an increase in the water level of the oceans and other water bodies. The east coast of the United States mainly comprises of the Atlantic Ocean and with the Atlantic Ice sheet melting it is the most vulnerable coast. The sea level if risen to an altitude greater than what is elevated then the people of the east coast will suffer. The presence of islands within the east coast which are called the barren islands provide the seawater a path to travel in the cities. Also, the area of the east coast is at a lower elevation, and this will provide no blockage to the rising seawater from flooding the cities. The slopes towards the coast are also gentle and not steep which will pave way for the seawater. All these reasons make the east coast most vulnerable.
