The strength of the Moon's pull changes from year to year, as the moon 'wobbles'Â in its orbit, slightly altering its position relative to Earth on a rhythmic 18.6-year cycle." In one half of the cycle, Loeb explained, the moon's force on the Earth causes low tides to grow and high tides to shrink; during the other half, high tides get bigger and low tides get lower.
But while the Moon's orbit is not something that humans can readily control, man-made climate change is the other half of the equation. ?
