climate change intensifying tropical cyclones accelerating sealevel rise increasing coastal flooding river deltas especially vulnerable flooding low elevations densely populated cities yet know many people live deltas exposure flooding using new global dataset show 339 million people lived river deltas 2017 89 people live latitudinal zone tropical cyclone activity calculate 41 31 million global population exposed tropical cyclone flooding live deltas 92 28 million developing least developed economies furthermore 80 25 million live sedimentstarved deltas cannot naturally mitigate flooding sediment deposition given coastal flooding worsen must reframe problem one disproportionately impact people river deltas particularly developing leastdeveloped economies
