Seas Have Drastically Risen Along Southern U.S. Coast in Past Decade
Scientists have been documenting abnormal and dramatic sea level rise along the US Gulf and Southeast coasts since about 2010, raising new questions about whether New Orleans, Miami, Houston and other coastal communities may be more at risk from rising sea levels than previously thought. While this acceleration has been relatively short-lived so far, it could have far-reaching consequences in areas of the United States that have experienced explosive development as the wetlands, mangroves, and beaches that once protected them shrink. “It disrupts your daily life,” said Thomas Wahl, professor of coastal hazards and engineering at the University of Central Florida. and co-author of the paper in Nature Communications. “It destroys the infrastructure. It damages cars that drive through salt water every day. You cannot open a business or go to work.” Then there’s the fact that in low-lying areas, even a small amount of sea level rise can make storm surges even more dangerous. The waves approach the shore, exacerbating erosion. “You now have higher levels of essential water,” says Wahl. “If you have a hurricane today compared to the same hurricane 150 years ago, the effect will be different.”
