Scientists have found that over the past two decades, the Earth has tilted by 80 centimeters: what does this mean
Kyiv • UNN
Scientists have discovered a shift in the Earth's rotation axis by 80 centimeters to the East due to the large-scale use of groundwater. From 1993 to 2010, more than 2,150 gigatons of water were pumped from underground reservoirs.
Scientists have found that over the past two decades, the intensive use of groundwater, which serves as a source of drinking water, has led to the tilt of the Earth's rotation to the East by almost 80 centimeters. This is reported by IFLScience, writes UNN.

Geophysicists have found that the pole of rotation is undergoing significant changes due to global processes, in particular climate change and large-scale use of groundwater. As Ki-Won so of Seoul National University explains, pumping out groundwater causes the rotation axis to shift, affecting the entire planet.
Ground water accumulates under the surface as a result of precipitation, seeping into natural reservoirs. These aquifers play an important role in providing water during periods of drought. They are a key component of the water cycle that provides life on Earth.
Today, about half of the world's population uses underground water as a source of drinking water, and a third — for irrigation. In the past, people dug wells and Wells to produce water, but since the 20th century, groundwater production has increased significantly. Between 1993 and 2010, more than 2,150 gigatons of water were extracted from underground reservoirs.
for Reference
The Earth's rotation pole is a point that constantly changes its location, a phenomenon known as polar motion. This process occurs due to changes in the mass distribution on the planet. Scientists compare it to a Spinning Top, whose rotation changes if its weight is redistributed. In the case of Earth, such a factor is water, which affects the rotation of our planet.
