Engineering360: "Groundwater extraction shifts Earth’s axis"

That seems like serious stuff. If the earth's axis is altered very much, then, it's orbit may change. A multitude of bad things can happen! It may be AMF!!

I agree--serious stuff, but was the study peer-reviewed? 31.5" change? but where? Why not given in degrees of tilt? There are a couple of other things missing or misstated; I need to ask for more info.

Yes, more definitive verifiable data must be presented. But the earth is a very fragile glob of mass. A little out of kilter here and there and AMF! The earth has had many changes in orbit, gravitational constant, magnetic flux density, and on and on. But none of the changes have been earth quencying. Since civilization has come on the scene about 10000 years ago, things have changed. We can now measure a lot of these earth threatning things. It's hard to distinguish what is real or just a bunch of number gyrations. It's hot now but it was also very hot when I was chopping and picking cotton in the Brazos bottom in 1950. Global warming is real and the ocean levels are rising and purchasing beachfront property in Arizona may not be a bad deal, afterall.

The picture is a bit misleading. The entire northern hemisphere is overlaid by a circle of radius 4 milliarcseconds. An arcsecond is about 101 feet, and 4 milliarcseconds is just short of 5 inches. I don't think we should panic.

Oh, dear! Something else to worry about!

Personally, I don't give a #^%@#.

Has anyone addressed the effect of dams on the rotation? I think dams would probably have more of an effect because of greater mass, even when not at the mid latitudes.

So many world damaging theories? When are we going to deal with the over population problem, this would diminish all the other troubles we seem to be having.
