Earth’s Tilt Shifts 31.5 Inches Due to Groundwater Pumping: Fact or Fiction?
Pumping groundwater has significantly altered Earth’s rotation, causing a 31.5-inch tilt in less than two decades due to the redistribution of approximately 2,150 gigatons of water. This movement of water, primarily from mid-latitudes like western North America and northwestern India, contributes substantially to sea-level rise, adding 0.24 inches. The study confirms groundwater redistribution as the largest climate-related cause of this rotational pole drift. This new understanding of groundwater’s impact on Earth’s tilt and sea levels can inform strategies to mitigate future climate change effects.
