A study conducted by researchers at Seoul National University has found that the Earth's rotational pole has shifted due to the extraction of groundwater.
Earth is, in many ways, a water world. Around two-thirds of its surface is covered in water, and the oceans that provide that cover make up over 96% of all water on Earth, according to the US Geological Survey. Glaciers and ice caps make up another 1.74%, but groundwater is the third most plentiful source at 1.69% of all water available on Earth. That’s an astonishing 23.4 million cubic kilometers of the stuff, dwarfing the mere 176,000 cubic kilometers contained in all the lakes in the world. But that does not mean the total amount of groundwater is unlimited, and removing it can have a lasting impact on more than just the people who use it for bathing and drinking. A new study points to how humans pumping out groundwater impacts Earth’s rotation.
