US to have major floods on daily basis unless sea-level rise is curbed – study

• New Orleans, Honolulu and Miami expected to be vulnerable
• Research: advancing tides will 'radically redefine the coastline'

Flooding events that now occur in America once in a lifetime could become a daily occurrence along the vast majority of the US coastline if sea level rise is not curbed, according to a new study that warns the advancing tides will "radically redefine the coastline of the 21st century".

The research finds major cities such as Honolulu, New Orleans and Miami will become increasingly vulnerable to elevated high tides and stronger storms fueled by the global heating caused by human activity. Beach and cliff erosion will exacerbate this situation.
