No, just the opposite. Everyone around the world, pee in the dry oil and water wells.

By pumping water out of the ground and moving it elsewhere, humans have actually shifted such a large mass of water that the Earth tilted nearly 80 centimeters east between 1993 and 2010 alone, changing the planet’s rotational pole, according to a new study published in the American Geophysical Union’s Geophysical Research Letters.
Sea level rise is one of the most significant phenomena associated with the warming climate. Contemporary sea level rise has been monitored extensively by multiple observational techniques.
The research was entitled “Drift of the Earth’s pole confirms groundwater depletion as a significant contributor to global sea level rise 1993-2010.”
Based on climate models, scientists previously estimated humans pumped 2,150 gigatons of groundwater, equivalent to more than six millimeters of sea level rise during this period – but validating that estimate has been difficult.
One approach lies with the Earth’s rotational pole, which is the point around which the planet rotates. It moves during a process called polar motion, which is when the position of the Earth’s rotational pole varies relative to the crust. The distribution of water on the planet affects how mass is distributed. Like adding a tiny bit of weight to a spinning top, the Earth spins a little differently as water is moved around.
“Earth’s rotational pole actually changes a lot,” said Ki-Weon Seo, a geophysicist at Seoul National University who led the study. “Our study shows that among climate-related causes, the redistribution of groundwater actually has the largest impact on the drift of the rotational pole.”
Water: Changing the Earth's rotation Water’s ability to change the Earth’s rotation was discovered in 2016, and until now, the specific contribution of groundwater to these rotational changes was unexplored. In the new study, researchers modeled the observed changes in the drift of Earth’s rotational pole and the movement of water – first, with only ice sheets and glaciers considered and then adding in different scenarios of groundwater redistribution.
The model matched the observed polar drift only once the researchers included 2,150 gigatons of groundwater redistribution. Without it, the model was off by 78.5 centimeters or 4.3 centimeters of drift per year.
“I’m very glad to find the unexplained cause of the rotation pole drift,” Seo said. “On the other hand, as a resident of Earth and a father, I’m concerned and surprised to see that pumping groundwater is another source of sea-level rise.”
The location of the groundwater matters for how much it could change polar drift; redistributing water from the midlatitudes has a larger impact on the rotational pole. During the study period, the most water was redistributed in western North America and northwestern India, both at midlatitudes.
Countries’ attempts to slow groundwater depletion rates, especially in those sensitive regions, could theoretically alter the change in drift, but only if such conservation approaches are sustained for decades, Seo said.
The next step for this research could be looking to the past. “Observing changes in Earth’s rotational pole is useful for understanding continent-scale water storage variations,” Seo said. “Polar motion data are available from as early as the late 19th century. So, we can potentially use those data to understand continental water storage variations during the last century. Were there any hydrological regime changes resulting from the warming climate? Polar motion could hold the answer.”
“This is a nice contribution and an important documentation for sure,” said Surendra Adhikari, a research scientist at the Jet Propulsion Laboratory who was not involved in this study. Adhikari published a 2016 paper on water redistribution impacting rotational drift. “They’ve quantified the role of groundwater pumping on polar motion, and it’s pretty significant.”
The rotational pole normally changes by several meters within about a year, so changes due to groundwater pumping don’t run the risk of shifting seasons. But on geologic time scales, polar drift can have an impact on climate, Adhikari added.
The magnetic pole shifts by a lot more than 4.3 mm per year. This study concerns the rotational pole.
I’ll admit I don’t know enough to say that the study is hogwash.
In antiquity, Polaris was not the north star, so you can’t use the stars to check your latitude. Maybe you could use the sun? The measurement error would be more than 4.3 mm though.
No, just the opposite. Everyone around the world, pee in the dry oil and water wells.
"Put, the water beck..."
The ethical pursuit of science and knowledge is dead.
But that’s just me.
Nope. It’s me too. First thing I thought actually. Given the forces and mass involved it idiotic.
WRONG! Everyone know climate change is the real cause of that. Just ask any Greeniac.
I can’t plan on any dates in the spring it seems. This year I could have put out my garden all of February. But March came in as a real bitch for the whole month and first half of April.
I wonder how soon before Biden’s handler’s administration prohibits anyone from drilling a well and shutting down all existing wells.
I suggest the study is that lovely form of hogwash powered by the magic of funding.
The measurement errors of which you speak before GPS and the like would still have been "accurate" enough when done many times a day to get someone close to a goal by more than 4.3mm.... From stars to sun to sextant, multiple daily checks and rechecks would function remarkably well, just as Newton's method for calculating for two unknowns by guessing the first and "checking towards zero" employing approximations on the way to getting "there."
Alternatively we can all stop pumping groundwater. This last is pure sarcasm directed at the Korean study, not at you.
Where did the water go? Probably it raised the oceans by an inch!
There are places where groundwater is being withdrawn; and, it doesn’t rain there. In other places, it is withdrawn at a rate that exceeds the annual rainfall. It is a problem, but unlikely the actual cause of pole shift.
I need to make model that shows that the world is tipping due to the left building solar panels and windmills!
LMAO
Hey, this is Grant Science - don’t expect intellectual probity or wit.
The interpretation of statistical noise is a subtle business!
This is idiotic. Such a a change is dwarfed by regular Continental drift that has been ongoing for billions of years.

In relatively rare locales I would agree with your point, but not as a general rule of thumb.
Phoenix Arizona has a great deal of trouble with low groundwater levels. All of Arizona follows suit.
Ooh...good points...I recall measuring the angle of the sun back in collegiate astronomy...I was in the ball park but probably off by at least 4.3 mm.
Now 4.3 mm is what, 2 billionth of a degree of latitude? Ellicott was off by more than that when he surveyed the Georgia-Tennessee line.
"So you're telling me that when all this water runs downhill it's going to settle and tip the earth over? What are your plans to prevent this?"
That’s the little wobble that the Earth has had since God set it spinning. Nothing to do with ground water.
