Earth's axial tilt
The study has revealed that the Earth's tilt has changed by 31.5 inches in less than two decades due to groundwater absorption.
Thus, let's see what the consequences will be for the Earth's rotation and its climate, sea level rise, and water redistribution.
Researchers led by Professor Ki-Wia Seo at Seoul National University in the capital of South Korea, Seoul, engaged in a geophysical study. They conducted research from 1993 to 2010.
Their research paper has been published in the journal 'Geophysical Research Letters'. The report states, “The Earth’s pole has moved eastward by about 80 cm due to groundwater withdrawal.
Since the study was conducted, 2,150 gigatons of groundwater have been withdrawn. This has also led to a 0.24 inch rise in sea level.
This has caused a change in the Earth’s mass distribution, leading to a tilt of its rotational axis. That is, the Earth’s tilt has increased by 4.36 cm per year and is currently 31.5 inches.
If groundwater flows back into the ocean, it will affect the polar motion. Since the Earth’s axis is tilted, there will be no immediate impact on the weather.
However, if the impact continues, it can have long-term effects. That is, changes in the Earth’s polar motion will affect the climate.
Therefore, sustainable water management measures must be taken.”
