McNoldy also noted that these walls are aging, and the back-to-back nature of storms is making seawalls more vulnerable. “More and more of them are gradually, completely submerged in saltwater, which concrete does not like.” “We do gradually put more stress on with sea level rise,” Brian McNoldy, a senior research associate at the University of Miami’s School of Marine and Atmospheric Science, told CNN.
This is putting even more stress on sea walls, which are meant to protect coastal communities from high waves and water levels. Scientists and researchers have long warned that sea level rise is leading to more erosion and high-tide flooding - particularly during extreme coastal storms.
