Human Overuse of Groundwater Alters Earth's Tilt.
TL;DR
Groundwater extraction and redistribution by humans caused the Earth's rotational pole to shift nearly a meter in two decades (1993-2010), contributing to a sea level rise, reveals a study in Geophysical Research Letters. The most water redistribution occurred in western North America and northwestern India, and efforts to reduce groundwater depletion in such areas could theoretically affect this shift. The phenomenon doesn't risk shifting seasons but could impact climate over geological time scales.
