Ice-sheet melts in Greenland and Antarctica are slowly causing rising sea levels which could be a threat to coastal cities. As ice-sheet modeling becomes more accurate, scientists are predicting global rises in water level will have a major impact on Boston’s city scape.
A study done in 2017 predicted a water level rise of as much as three feet by 2050 in the Boston area. However, the study was recently redone, with an outcome of an expected water level rise of around 1.25 feet. While the slower rise is reassuring, this could still do a great deal of damage to Boston.
Higher water levels will lead to more frequent flooding– especially dangerous to the Dorchester area, which contains buildings built on landfills, and houses a significant portion of Boston’s population. By 2050, ten times as many floods as there are today are anticipated in Boston. The coastline, Seaport, Dorchester, and MBTA lines are at highest risk of floods currently, but rising sea levels will put much more of Boston at risk.
By the end of the century, water levels in Boston are expected to be two feet higher than they are now. Government officials in Boston are looking for ways to combat this problem.
