"As economic activity and populations continue to expand in coastal urban areas, particularly in Asia, hundreds of trillions of dollars of infrastructure, industrial and office buildings, and homes are increasingly at risk from intensifying storms and rising sea levels."
"By the middle of the century, the scores of billions it cost to compensate the greater New York City area for being unprepared for superstorm Sandy may seem like a bargain. Without major adaptation measures to increase the level of storm protection beyond a 1-in-100-year event, the value of the city’s buildings, transportation, and utilities utility infrastructures currently at risk from storm surges and flooding — an estimated $320 billion — will be worth $2 trillion by 2070, according to continuing studies by the Organization for Economic Cooperation and Development (OECD).
By then, the OECD says, the metropolitan area will rank behind only Miami and Guangzhou, China, at the head of a list of the world’s megacities with the most flood-vulnerable assets. In all these cities, sea level rise will meet a tide of urbanization in the coming decades and set the scene for storms with ever-more catastrophic consequences.
Some of those cities with the most at-risk assets now — Tokyo, New Orleans, Amsterdam, Rotterdam, and Nagoya — will, over the next 50 years, be surpassed by Calcutta, Shanghai, Mumbai, Tianjin, Bangkok, Ningbo, and Ho Chi Minh City, booming Asian coastal metropolitan areas where trillions of dollars in economic assets will be vulnerable. So will many millions of these cities’ residents, most of them poor and living in low-lying areas."
