Whatever the true linear increasing rate of the present global sea level rise is, a look on the data after subtracting a linear function of +3.2 mm per year from the Colorado sea level data shows a remarkable oscillation of about ~ 6.15 periods per year, because this is twice the synodic frequency of Mercury, Earth and Jupiter, with the frequencies of Mercury (4.15204 y ^ -1), Earth (0.9998 y ^ -1) and Jupiter (0.084317 y ^ -1): F = 2 * (4.15204 — 0.99998 — 0.
