How the moon's "wobble" will impact coastal cities

CA, 17 Jul 2021
As a new study from NASA points to a “wobble” in the moon’s orbit as being responsible for a potential rise in high-tide floods over the next several years, several experts are warning that such extreme changes in weather are already happening — and will be much more pronounced by the effects of climate change.

The study, published in the journal Nature by researchers from NASA and the University of Hawaii, suggested that upcoming changes in the moon’s orbit could lead to record flooding across coastal locations in the U.S. within the next decade.

The moon wobble and its effects are not exactly new, however, after first being observed in the 1700s as part of an 18.6-year cycle.

While the changing effects of the moon’s gravitational pull on the Earth’s waters have been observed for hundreds of years, it will be humanity’s worsening environmental footprint that will exacerbate, and accelerate its effects.
