NASA says moon ‘wobble’ will cause surge of coastal flooding by 2030s

On July 7, NASA announced their findings on the relationship between the moon, coastal flooding, and what that could mean in the next 15 years.

The National Oceanic and Atmospheric Administration (NOAA) has reported an increase in high-tide floods in many U.S. coast cities. In 2019, there were 600 occurrences of this kind of flooding. However, a recent study done by NASA Sea Level Change Science Team from the University of Hawaii claimed that there would be a massive increase in this kind of flooding beginning in the mid- 2030s.

There are concerns that these floods could last days, weeks, or months, which would cause problems for health, safety, employment, and infrastructure, among other things. There are a couple of reasons for this. The Earth, Moon, and Sun line up in different variations, which causes a strong gravitational pull. The ocean tides are related to the Moon, specifically the Moon’s wobble.

The wobble was discovered in 1728 and the regular wobble cycle takes 18.6 years. Between the regular wobble, a warmer planet, and higher sea levels, increased flooding is quite possible. The researchers found this information by studying sea levels and other water patterns around the U.S., barring Alaska. Their findings allowed them to make predictions up until the  2080s. They hope the information they found and released will allow government officials and the general public to be able to plan for the increased flooding and take the right measures.
