EPA: Don’t expect to hold back rising seas
By Darryl Fears
26 June 2011 From his government office in Virginia Beach, Clay Bernick can see the future, and that future looks a rather lot like the movie Waterworld. The sea level is rising in Virginia Beach and the entire area known as Hampton Roads because of the warming climate, and the area also happens to be sinking for other geological reasons. Within 50 years, a big part of Virginia Beach’s identity — its beach — could be lost if nothing is done, said Bernick, the city’s environment and sustainability administrator. Large pieces of land could also be lost to the ocean in Norfolk within a few generations. In fact, the National Oceanic and Atmospheric Administration warns that, outside of greater New Orleans, Hampton Roads is at the greatest risk from sea-level rise for any area its size. “It’s a significant threat,” Bernick said. “At this point, I wouldn’t put it in the category of fear, because it’s a long way off.” But he added: “You’ve got multiple factors with flashing lights saying, ‘Okay, guys, what are you going to do?’ ” To help answer that question in the past, municipalities turned to a manual published by the Army Corps of Engineers since 1954 on how to protect shores by holding back the sea. But earlier this month, the U.S. Environmental Protection Agency published the first manual on how not to hold it back, arguing that costly seawalls and dikes eventually fail because sea-level rise is unstoppable. The federal Global Change Research Program estimates that the sea level will rise 14 to 17 inches in the next century around Hampton Roads. The analysis, Rolling Easements [pdf], published on the EPA’s Web site, hopes “to get people on the path of not expecting to hold back the sea” as the warming climate is expected to melt ice around the globe, EPA researcher James G. Titus said. […]
