Humans may have changed the Earth’s circulation by withdrawing large amounts of water from the Earth between 1993 and 2010, a study has found.
According to research published in the journal Geophysical Research Letters, the earth’s surface has tilted about 80 cm to the east due to the massive withdrawal of groundwater.
Previous studies have shown that the Earth’s axis has shifted and the Earth has started to rotate slightly differently due to the movement of water.
According to the estimates made by scientists, humans have extracted 2 thousand 150 gigatons of water from the earth from 1993 to 2010, the amount of which is 6 mm higher than the sea level.
The ability of water to alter the Earth’s circulation was first discovered in 2016. However, the specific contribution to groundwater circulation variability is still unclear.
In this new study, researchers in space on Earth’s axis Change and movement of water observed. In this study, first the effects of ice sheets and glaciers were examined, then the rearrangement of underground water was observed in different contexts.
“Earth’s axis of rotation changes a lot,” said Ki-Weon Seo, a geophysicist at Seoul National University in South Korea and co-author of the study.
Research shows that groundwater redistribution has a major impact on the Earth’s axial slippage. In the model made by the scientists, it was found that the axis has shifted 78.5 cm to the east at a speed of 4.3 cm per year due to the extraction of 2150 gigatons of water from the earth.
