Only a month ago we could witness the vulnerability of a coastal city. Hurricane Sandy hit the New York agglomeration, causing 253 fatalities and an economic loss of an estimated 65 billion dollar. Rising sea levels could threaten many coastal cities worldwide. The French based Organisation for Economic Co-operation and Development (OECD) explored the city-scale risks of climate change and conducted a list of coastal cities that are most exposed to coastal flooding in terms of both economic loss and exposed population.
So here’s a list of top 10 cities most exposed to coastal flooding in terms of current exposed population.
