You're right, but the height of the sea wall doesn't change. And it's the same level now that's it's been for years. I made the point about the width of the beach because the loons crying sea level rise point to beach erosion as proof of their claim.
The loons are loons. Virginia Beach has beach erosion because that’s the way the currents work. When I lived in Norfolk, we’d go out to Sandbridge after a big storm to see if any of the houses had disappeared.
