The study, conducted by NASA and the University of Hawaii, examined ongoing sea-level rise and the dire situation coastal cities will face during the next lunar shift, or “wobble,” CBS News reported.
The so-called wobble that occurs in the moon’s orbit is a naturally occurring phenomenon that was first documented in 1728 and happens every 18.6 years — resulting in changes in the tides.
“In half of the Moon’s 18.6-year cycle, Earth’s regular daily tides are suppressed: High tides are lower than normal, and low tides are higher than normal,” NASA said.
“In the other half of the cycle, tides are amplified: High tides get higher, and low tides get lower. Global sea-level rise pushes high tides in only one direction – higher. So half of
