Earth Has Tilted 31.5 Inches

NBC News -  Pumping groundwater appears to have a greater consequence than ever previously thought. But now—thanks to a study published in the journal Geophysical Research Letters—we can see that, in less than two decades, Earth has tilted 31.5 inches as a result of pumping groundwater. This equates to.24 inches of sea level rise.

“Earth’s rotational pole actually changes a lot,” Ki-Weon Seo, a geophysicist at Seoul National University and study lead, says in a statement. “Our study shows that among climate-related causes, the redistribution of groundwater actually has the largest impact on the drift of the rotational pole.”

With the Earth moving on a rotational pole, the distribution of water on the planet impacts distribution of mass. “Like adding a tiny bit of weight to a spinning top,” authors say, “the Earth spins a little differently as water is moved around.”
