(CNN) -- Two years ago next week, Superstorm Sandy barreled through parts of the United States, causing $65 billion worth of damage to communities up and down the Eastern seaboard. Sandy, which brought extensive flooding to New York and Atlantic City, was described by many as a once in a generation storm. But in the coming years, thanks to global warming, it won't take superstorms like Sandy to bring regular and potentially dangerous flooding to parts of the United States. Tidal flooding used to be a relatively rare occurrence along the East Coast and the Gulf of Mexico, generally happening only occasionally at high tide or king tide, when the sun and the moon are aligned. But based on what scientists already know about climate change, it is clear that sea levels are going to rise over the next few decades. Coastal flooding is expected to occur even more often and cause more disruption. This will redefine how and where coastal residents live, work, and go about their daily routines.
