Human needs have once again impacted our planet, as Earth’s rotational pole has shifted significantly due to excessive groundwater extraction, according to a study published in Geophysical Research Letters. Led by Seoul National University’s Ki-Weon Seo, the research found that Earth’s pole shifted approximately 80 centimeters eastward because of groundwater depletion.
The study revealed that humans have pumped out around 2,150 gigatons of groundwater during the study period. Additionally, sea levels rose by 0.24 inches, and the distribution of Earth’s mass was altered due to the massive extraction of groundwater. This led to the drifting of the rotational pole at a rate of 4.36 centimeters per year.
Now, researchers expressed concerned that continued depletion of groundwater could lead to long-term climatic impacts.
The planet’s twitch, recognized as polar motion, is the subtle movement of our planet’s rotation axis relative to its crust, nudged by the ever-changing balance of mass worldwide. This interesting act is influenced by prominent factors, such as groundwater moving from deep underground reservoirs to the vast oceans.
The study’s models indicate that groundwater depletion affects polar drift more significantly than previously thought, surpassing the impact of climate-related factors like ice sheet melting.
As per the research, regions such as western North America and northwestern India have impacted the polar drift as these are the places where significant groundwater extraction has occurred. Notably, the areas fall in mid-latitude and has played a crucial role in impacting the polar drift due to their geographical location and the volume of water extracted.
As our earth tilts, it doesn’t cause an instant shift in our weather or seasons. However, scientists bring to our attention the concern that our water sources keep shrinking and this could inevitably cause shift in our climate over time. As our poles subtly move over long spans of time, our climate feels the changes. So, it’s crucial that we practice water preservation to maintain a balanced climate.
Notably, the phenomenon of Polar motion is like Earth doing a dance, with the planet’s axis making a little shift in its rotation tied to the Earth’s crust. This delicate shift is influenced largely by how weight is tossed around all over the planet.
These findings serve as a wake-up call for global policymakers and environment champions. They underscore the urgency to address the issue of groundwater depletion not as an isolated problem, but as an integral part of the battle against climate change and the measure to manage our natural resources sustainably.
