Climate Change Threatens to Cause Trillions in Damage to World's Coastal Regions If They Do Not Adapt to Sea-Level Rise

New research predicts that coastal regions may face massive increases in damages from storm surge flooding over the course of the 21st century.

According to the study published in the Proceedings of the National Academy of Sciences, global average storm surge damages could increase from about $10-$40 billion per year today to up to $100,000 billion per year by the end of century, if no adaptation action is taken.

The study, led by the Berlin-based think-tank Global Climate Forum (GCF) and involving the University of Southampton, presents, for the first time, comprehensive global simulation results on future flood damages to buildings and infrastructure in coastal flood plains.  Drastic increases in these damages are expected due to both rising sea levels and population and economic growth in the coastal zone.  Asia and Africa may be particularly hard hit because of their rapidly growing coastal mega-cities, such as Shanghai, Manila and Lagos.
