Few things seem as stable and predictable as the moon. It goes from new to full and back again every month. It moves the tides. The same side always faces Earth. And every so often, it temporarily blocks the sun.
But here’s something most people probably don’t know about the moon: It wobbles. Some years, the wobble lowers tides. But in the years ahead, the opposite will happen—the wobble will make high tides much higher. Combine these unusually high tides with sea-level rise caused by climate change, and we have a perfect storm for rapid increases in the frequency of tidal flooding across coastlines, as documented in a new report from NASA and researchers at the University of Hawaii.
