As this year’s hurricanes marched across the Caribbean into the Gulf Coast or out to the North Atlantic, cities along the U.S. northeastern coast knew they were dodging bullets.  If Boston gets hit by a storm like Hurricane Harvey, mayor Marty Walsh acknowledged in a radio interview, “we are wiped out as a city.”

Back in 2012, Superstorm Sandy offered a heads-up on hurricane risks, killing 43 people and causing US$19 billion of damage in New York City alone as it pulled in a surge of seawater that rose more than 5 feet (1.5 meters) above ground level in many neighborhoods.  If Sandy’s remnants hadn’t missed Boston’s high tide by a few hours, a similar storm surge would have swept across low areas of the city.

Today, a Massachusetts Institute of Technology (MIT) analysis suggests, a Category 1 hurricane with a few feet of surge on top of a high tide could flood a quarter of a million Boston residents.  And climate change is bringing more intense storms and rising tides.
