Mari N. Jensen in the University of Arizona News: Rising sea levels could threaten an average of 9 percent of the land within 180 U.S. coastal cities by 2100, according to new research led by University of Arizona scientists. The Gulf and southern Atlantic coasts could be particularly hard hit. Miami, New Orleans, Tampa, Fla., and Virginia Beach, Va. could lose more than 10 percent of their land area by 2100.The research is the first analysis of vulnerability to sea-level rise that includes every U.S. coastal city in the lower 48 with a population of 50,000 or more. The latest scientific projections indicate that by 2100, the sea level will rise about 1 meter – or even more. One meter is about 3 feet.
At the current rate of global warming, sea level is projected to continue rising after 2100 by as much as 1 meter per century. "According to the most recent sea-level-rise science, that's where we're heading," said lead researcher Jeremy L. Weiss, a senior research specialist in the UA's department of geosciences. "Impacts from sea-level rise could be erosion, temporary flooding and permanent inundation."…
