The reason why the Earth's axis tilted, according to a study

'According to a South Korean study published in the journal Geophysical Research Letters', mankind has sucked so much water from underground that it has affected the tilt of the Earth's axis.

According to researchers at Seoul National University, the massive extraction of water from underground for over a decade has affected the tilt of the Earth's axis, shifting it eastwards at a rate of about 4.3 centimetres per year.

According to the researchers, this study would show that among the causes linked to climate change, the redistribution of groundwater could actually have the greatest impact on the pole shift.

The impact on seasonal changes
According to a NASA researcher who did not participate in the study, Surendra Adhikari, the ebb and flow of seasonal change is linked to the angle of the Earth's rotational axis and over time, an erratic axis could affect climate on a global scale.

The role of the human being
For the researchers who carried out the study, humans should be aware that they have influenced the earth's systems in various ways. The problem of underground water resources is also related to the fact that they are exhaustible resources, which then take a long time to reform.

An important documentary contribution
For NASA scientist Adhikari, the South Korean study is an important documentary contribution because the role of groundwater pumping on polar movement has been quantified and is quite significant.
