The lawns of homes purchased this year in vast swaths of coastal America could regularly be underwater before the mortgage has even been paid off, with new research showing high tide flooding could become nearly incessant in places within 30 years. Such floods could occur several times a week on average by 2045 along the mid-Atlantic coastline, where seas have been rising faster than nearly anywhere else, and where lands are sagging under the weight of geological changes.
Washington and Annapolis, Md. could see more than 120 high tide floods every year by 2045, or one flood every three days, according to the study, published last week in the journal PLOS ONE. Thats up from once-a-month flooding in mid-Atlantic regions now, which blocks roads and damages homes. The flooding would generally cluster around the new and full moons, said Erika Spanger-Siegfried, a Union of Concerned Scientists analysts who helped produce the new study. Many tide cycles in a row would bring flooding, this would peter out, and would then be followed by a string of tides without flooding.
he analysis echoed findings from previous studies, though it stood out in part because of its focus on impacts that are expected within a generation instead of, say, by the end of the century. It showed high tide floods along southeastern shorelines are expected to strike nearly as often as they will in the mid-Atlantic, portending a fast-looming crisis for more than 1,000 miles of coastal America.
Seas have recently been rising worldwide by an average of about an inch a decade, a rate of change thats accelerating as global warming expands oceans and causes ice to melt. The East Coast endured sea level rise at more than twice the global rate from 2002 to 2014.
