Climate change could raise coastal flood risk

The number of people threatened by coastal flooding could more than triple by 2070 due to climate change while the financial impact could surge by tens of trillions of dollars, according to a prominent international organization.
Angel Gurria, secretary general of the Paris-based Organization for Economic Cooperation and Development, called for quick action to buy time for cities at risk. It can take 30 years to put defenses for vulnerable cities in place, a report published by the organization Tuesday said.
