Rampant groundwater pumping has changed the tilt of Earth’s axis

www.nature.com Rampant groundwater pumping has changed the tilt of Earth’s axis

Human depletion of underground reservoirs has shifted the global distribution of water so much that the North Pole has drifted by more more than 4 centimetres per year.

Not alarmist, just cool. When I was in grad school we studied we used dInSAR to study groundwater pumping related subsidence. It makes perfect sense that there would be mass redistribution.
