Moon wobbles in space, may cause devastating floods on earth

    According to the National Space and Aeronautics Administration, “There’s nothing new or dangerous about the wobble; it was first reported in 1728. What’s new is how one of the wobble’s effects on the moon’s gravitational pull—the main cause of Earth’s tides—will combine with rising sea levels resulting from the planet’s warming.
    To our eyes, the moon appears to “wobble” in space because of its tilt, velocity and shape of its orbit, taking 18.6 years to complete.

    WASHINGTON, DC — Cyclical shift in the moon’s orbit may cause gravitational pull that would either suppress or amplify tides on earth with the global sea-level rise pushing high tides in only one direction, higher.

    This phenomenon, according to NASA, could create an onslaught of coastal flooding starting in the mid-2030s due to what has been termed as a ‘wobble’ in the moon’s orbit.

    NASA warns with the possibility of a so-called ‘wobbling’ moon, numbers of floods could quadruple as the gravitational effects of the lunar cycle combine with climate change to produce “a decade of dramatic increases” in water disasters.

    A ‘wobbling’ moon means a cyclical shift in the moon’s orbit that was first reported in 1728 and happens every 18.6 years says the space agency. With such an occurrence, coastal cities would experience “rapidly increasing high tide floods” and they would occur in ‘clusters’ lasting a month or longer.

    During the other half of the cycle, tides are amplified, meaning high tides get even higher, and low tides get even lower. As global sea levels rise, the amplification effect will be increased. The next time this ‘lunar assist’ to high tides comes around will be in the mid-2030s. By that time global sea levels will have been rising for another decade.

    It will have passed a ‘tipping point’ and the result will be a “leap in flood numbers on almost all US mainland coastlines,” says NASA. (TRC/The MiNT)
