Sea level has risen by about eight inches overall worldwide since around 1900 and the waters are expected to rise an estimated three feet by 2100. “Sometimes we forget that the damage in New Orleans in 2005 from Hurricane Katrina came not from wind or rain, but from the storm surge [that caused flooding] ahead of that storm,” Lemonick says. If sea levels rise as expected, “all of those storm surges are going to be starting from a level three feet higher, which means that they have much greater potential to drive inland, to wash over barrier islands, and to really inundate the coast. … Many, many millions of people and trillions of dollars of infrastructure are in serious danger, if those projections are correct.”
