In recent years the number of scientific studies accumulate like never before, thanks also to the greater amount of data obtained from new implemented technologies and even artificial intelligence that helps massive amounts of information provided.
Specifically, the Earth’s pole has moved 80 centimeters, towards 64.16°E at a speed of 4.36 cm/year during 1993-2010according to data published in the journal Geophysical Research Letter, by experts from the Seoul University.
In this scientific study, the authors sought to establish a causal relationship between sea level rise and the resulting change in the Earth’s axis of rotation due to groundwater use. “Has occurred a problem in the Earth’s axis of rotationand it is related to human activities,” warned Seo Ki-won, professor at the Department of Earth Sciences Education at Seoul National University and lead author of the document.

Estimates from climate models show significant depletion of groundwater during the 20th century, which is consistent with the analysis of the global mean sea level (GMSL) budget. And they have concluded that the anthropogenic contribution was important to the current depletion of groundwater as a result of irrigation.
Scientists previously estimated that between 1993 and 2010, humanity pumped 2,150 gigatons of groundwater, or more than 6 millimeters (0.24 inches) of sea level rise, based on climate models.
In turn, the scientists found that The North Pole is “tilting” towards Canada, but so far they have not been able to clearly explain why. In 2016, it was discovered that water could alter the Earth’s rotation, but until now the precise role of groundwater in these rotation changes had not been studied.

In the current study, scientists used computer simulations to simulate the reported changes in derives from the Earth’s rotational pole and water movement, initially simply taking into account ice sheets and glaciers and then including various groundwater redistribution scenarios.
Ki-Weon Seoa geophysicist at Seoul National University who led the study, said: “I am very pleased to find the unexplained cause of rotation pole drift. On the other hand, as a resident of Earth and a parent, I am concerned and surprised to see that groundwater pumping is another source of sea level rise.”
Since the total amount of water on Earth does not change, it is said that if groundwater is artificially pumped and used by humans and discharged into the ocean, sea level will inevitably rise. So, as the distribution of the amount of matter on Earth changes, the Earth’s axis of rotation is also altered.
While, Surendra Adhikari, Research scientist at the Jet Propulsion Laboratory in Pasadena, California, remarked: “This is a good contribution and important documentation, without a doubt. “They have quantified the role of groundwater pumping in polar motion, and it is quite significant.”
“The pole of rotation typically shifts by several meters in about a year, so changes due to groundwater pumping are not at risk of changing seasons. But on geological time scales, polar drift can affect the climate,” the specialist added.
And he concluded: “Observing changes in the Earth’s rotation pole is useful for understanding variations in water storage on a continental scale. Data on polar motion have been available since the end of the 19th century. Therefore, we can potentially use that data to understand variations in continental water storage over the past 100 years.
When they first observed the change in the axis of rotation, experts explained that the reasons were the acceleration of global warming, melting glaciers, rising sea levels and ice drift.
In addition, they confirmed that there was a rise in sea level of 4 to 8 millimeters (mm) due to the loss of glaciers in Antarctica and 6 to 8 mm as a result of the loss of ice in Greenland.
