The moons gravitational pull helps drive Earths tides.In half of this lunar cycle, Earths routine day-to-day tides are diminished, with high tides lower than normal and low tides greater than typical. In the cycles other half, the circumstance is reversed, with high tides higher and low tides lower.The anticipated flooding will result from the mix of the continuing sea level increase associated with environment change and the arrival of an amplification part of the lunar cycle in the mid-2030s, the researchers said.”This result from the moon triggers the tides to vary, so what we discovered is that this result lines up with the underlying sea level rise, and that will trigger flooding particularly in that time duration from 2030 to 2040,” Hamlington said.Waves at high tide make their way over rocks and onto the roadway in Oceanside, California, U.S., November 27, 2019.
