'Changes' means, that a difference occurs, which the GPS-system is able 
to detect.

These changes are not absolute values. What we're talking about is the 
radius of the Earth. Since the reference is the surface of Earth, these 
changes are not a measurement of the diameter itself, but based on a 
reference point on top of a radius.

But 'Odd Bodkin' claimed, that GPS could measure the diameter to this 
precision. This I have rejected, since GPS does not measure the Earth' 
diameter at all.

Actually it's even more complicated, since the meter itself is based on 
the size of the Earth, as it was once defined as 10 millionth part of 
the distance from pole to equator (along the meridian through Paris).

According to this definition: if the Earth would grow, than also the meter.

Now the meter is defined by means of light and as fraction of a 
light-second.

Unfortunately the length of a second is also a function of hight (as 
seen in the experiments at the Harvard towers).

So we had use other means and show Growing Earth in the fossil records 
or in geological formations.

This could be done by searching for marine fossils in high places, like 
mountains.

And - sure - we find fish-bones and shells in all sort of high places. 
Also sand and pebbles are found in several locations, where today is no 
water.

Other possibility: ancient harbours.

E.g. it is actually possible to interpret certain ruins as harbours, 
even if they sit on a mountain top.

Direct measurement is actually difficult, since these changes are VERY 
slow and GPS didn't exist a million years ago. (Actually it didn't even 
exist a thousand years ago - not even one hundred).
