Report: 150 million could be affected by 2070 at cost of $35 trillion

PARIS - The number of people threatened by coastal flooding due to climate change could more than triple by 2070 and the financial impact could balloon to $35 trillion, according to a report released Tuesday by the Organization for Economic Cooperation and Development.
