Yet another grossly unscientific article attempting to drum up support for anthropogenic global warming. After doing some REAL SCIENCE, we find that Mankind’s absolute maximum contribution to the wobble of our planet is 22,000 times SMALLER than a human hair.
To see how we arrived at this figure, follow along as we do some REAL SCIENCE!!!
Earth weighs 1.32E+25 lbs. That comes to 6.58E+12 Gtons. Greenland has lost 7,500 Gtons. The Earth weighs nearly a billion times more than the lost ice mass (877,786,667 times more, to be precise).
The pull of gravity from the sun and the moon contribute to the planet’s wobble. So do variations in atmospheric pressure, ocean loading and the wind, which change the position of the Earth’s axis relative to the surface. Together their effect is called the Chandler wobble, and it has a period of 435 days.
Another force causes the rotational axis to move over a period of a year. This “annual wobble” is due to the Earth’s elliptical orbit around the sun.
Between these two effects, the Earth’s axis migrates irregularly along a circular path with a radius of up to 20 feet (6 meters).
Moreover, precession is a change in the orientation of the rotational axis of a rotating body. In an appropriate reference frame it can be defined as a change in the first Euler angle, whereas the third Euler angle defines the rotation itself. Meanwhile, nutation (from Latin n?t?ti?, “nodding, swaying”) is a rocking, swaying, or nodding motion in the axis of rotation of a largely axially symmetric object, such as a gyroscope, planet, or bullet in flight, or as an intended behavior of a mechanism. In an appropriate reference frame it can be defined as a change in the second Euler angle.
Pinning down the overall wobble of the planet’s rotation is key to keeping certain tracking systems like GPS accurate. Until recently, this was done through a complicated process that involves 30 radio telescopes around the globe that measure the direction between Earth and specific quasars, a type of galaxy that is assumed to be stationary relative to the Earth. More recently, the Wettzell Geodetic Observatory, in the Bavarian Forest of southeast Germany has been using a pair of highly precise ring laser gyros (Live Science. (2011).

NOW… Remember when we calculated that the Earth weighs 877.8 million times more than Greenland’s lost ice mass? Even if 100% of Greenland’s
lost ice mass was due to human effect, the absolute greatest contribution to Earth’s wobble would be 6.84E-9 meters. (6 meters / 877,785,667). That’s 6.84 nanometers (nm), less than 70 helium atoms lined up side by side. Only just this summer, in June, was mankind capable of shrinking the size of computer circuits that small. “As of June 2018, mass production of 7 nm devices has begun.” That’s 22,000 times SMALLER than a human hair.
Seriously, folks. This is SCIENCE. It’s what reasonable, rational people use to piece through the blitheringly idiotic mudstream media BS.
Mankind’s absolute maximum contribution to the wobble of our planet is 22,000 times SMALLER than a human hair, but it’s still nearly a billion times less than the mass of the entire planet. Heck, that’s so small, that as of August 22, 2018, only two companies on the planet are even capable of making semiconductors with traces that small!
That’s roughly the same effect as tossing a baseball off the deck of a U.S. Aircraft Carrier.
So, before, based on this article, a bunch of greenies were screaming, “OMG! Our planet is going to shake itself to death and it’s all our fault!!!” Now, however, armed with REAL SCIENCE, we see mankind’s absolute greatest effect on the wobble is to incredibly tiny, 22,000 times smaller than the width of a human hair, that we will never be able to measure it.
As for crust rebound, the effect is similarly minuscule. Changes in the Earth’s very slowly moving mantel and far more rapidly moving molten core outweigh ice mass, crust rebound, and even changes in ocean currents millions of times over.
