The Journal of Geophysical Research has published a new study showing that the Earth’s poles have moved over the past three decades. displacement is about 80 cm. What could be the cause of this change?
situation
The Earth’s pole has moved about 80 centimeters to the east over the past three decades. The change occurred between 1993 and 2010, according to Phys.org.
Reason
The main reason for this is the pumping of groundwater. The Earth’s axis of rotation shifted in the 1990s. This shift was previously thought to be the result of groundwater withdrawal, thawing, and other factors leading to sea level rise.
However, in 2016, researchers discovered that water has the power to change the Earth’s rotation.
Until this discovery, little was known that these rotational changes were due to the contribution of groundwater.
According to Phys.org. site, it is estimated that humans have pumped out 2,150 billion tons of groundwater. This equates to a sea level rise of 6 millimeters between 1993 and 2010.

However, evaluation is difficult.
Ki-Weon Seo, a geophysicist at Seoul National University, told the website, “Earth’s rotational pole is really changing a lot.”
The man has conducted studies and thus has made statements like, “Our study shows that among climate-related causes, the redistribution of groundwater actually has has the greatest effect on the displacement of the rotating poles.”
At that point, they discovered that the groundwater distribution (2,150 gigatons) needed to be included in the model to match observations of Earth’s polar displacement.
Connect with India
According to the study, most of the water is redistributed in western North America, as well as in northwestern India. On the other hand, as an Earthling and as a father, I am concerned and surprised to see groundwater pumping as another cause of sea level rise.
The authors add: “Earth’s poles moved towards 64.16°E at a rate of 4.36 cm/year between 1993 and 2010 due to groundwater depletion and resulting sea level rise. “.
Solution
The solution is very simple. According to the study, if countries managed to minimize groundwater depletion, especially in sensitive areas, this change could theoretically be reversed. However, this is only relevant if such efforts continue for decades and decades.
