Sunday SciKu | King Tides

Who knew that the moon’s orbit wobbled on an 18.6-year cycle? Well, actually, we’ve known about this since 1728—and Bronze Age peoples knew about it thousands of years ago, and tracked it in their megalithic monuments all over the world.

But a paper in Nature Climate Change this week studied the impact it will have on high tide flooding in the coming decades. Right now we’re approaching the major standstill, where tides variation is the lowest, hiding the impacts of sea level rise on coastal flooding. In 2034, we’ll be at the minor standstill, which exacerbate the flooding.
