The US cities at risk of flooding; and how they're dealing with the threat

Rising sea levels pose a serious threat to cites like Boston, New York and Miami Beach. So what are they doing to protect themselves?

Tropical storm Harvey may have bared its teeth at Houston, but other cities in the US have felt the pangs of nervousness. Several cities are vulnerable to the fiercer storms and sea level rise that are being fueled by climate change.

Cities, by their very nature, struggle during flood situations. Water that would have been soaked up by grass and other vegetation washes off the concrete and asphalt of urban areas and, if not properly diverted away, can inundate homes.
