A new study from NASA has a pretty stark finding — major floods will become more common in occurrence in the United States by the 2030s because of a change in the moon’s orbit.

  • In fact, the study said the majority of the U.S. coastline will see three-to-four times more high tide floods each year for at least 10 years.

Will there be more floods?

The study — published in the journal Nature Climate Change — said the flood days won’t come at a certain time of year. In fact, they “are likely to cluster together over the span of just a few months,” according to Live Science.

  • And the “coastal areas that now face just two or three floods a month may soon face a dozen or more,” Live Science reports.

Why will there be more floods?

The study suggests that there will be a “wobble” in the moon’s orbit, which will cause the rise in flooding.

  • According to Futurism, “scientists predicted that the lunar wobble will cause increased clusters of flooding that will significantly disrupt life and damage infrastructure throughout coastal cities that have acclimated to far milder and less frequent floods — an eerie reminder of Earth’s close relationship with its natural satellite, and perhaps even a pressing infrastructure issue.

What this means

More floods mean there will be changes to the livelihoods of many Americans, especially if city organizers don’t start planning for them now, according to the study. Specifics weren’t mentioned in the study, though.

  • “It’s the accumulated effect over time that will have an impact,” said lead author Phil Thompson, according to CBS News. “If it floods 10 or 15 times a month, a business can’t keep operating with its parking lot under water. People lose their jobs because they can’t get to work. Seeping cesspools become a public health issue.”
