New Delhi: A recent study published in the journal Nature has unveiled a concerning discovery, suggesting that the excessive pumping of groundwater has resulted in a shift in Earth's spin. Scientists from Seoul National University in South Korea conducted the research and found that the Earth's rotational pole has moved approximately 80 centimetres (31.5 inches) eastward since 1993.

According to the study, this alteration in Earth's rotational pole can be attributed to the redistribution of water mass across the planet. As groundwater is extracted from aquifers, it is replaced by seawater, which possesses a different mass. This discrepancy in mass distribution subsequently influences the Earth's rotational axis. Humans have extracted 2150 gigaton from earth in the timeframe of 17 years.

The implications of this finding are significant, particularly for our understanding of climate change. The Earth's rotational pole plays a crucial role in determining the global distribution of sunlight and heat, meaning that a shift in the pole's position can lead to changes in weather patterns and overall climate. The study's authors stress the need for further research to fully comprehend the extent of the impact caused by groundwater pumping on Earth's rotation. Nevertheless, they view their findings as an urgent call to action, emphasizing the necessity for sustainable management of groundwater resources.

Here are some additional key insights from the study:

1. Satellite data was employed to monitor groundwater movement and changes.
2. Notable groundwater pumping was identified in India, China, and the United States.
3. The researchers predict that the eastward shift of Earth's rotational pole will persist as groundwater extraction continues.
