Has The Earth Tilted Recently 2024. The way humans pump groundwater from the planet's interior has changed earth's tilt by 31.5 inches (80 centimeters) between 1993 and 2010. Polar drift in the 1990s explained by terrestrial water storage changes via agu
The study included data from 1993 through 2010, and showed that the pumping of as much as 2,150 gigatons of groundwater has caused a change in the earth’s tilt of roughly 31.5 inches. By pumping water out of the ground and moving it elsewhere, humans have shifted such a large mass of water that the earth tilted nearly 80 centimeters (31.5 inches) east.
