Feeling tilt-y? Irrigation has shifted the location of the North Pole.
But those repeated vacillations aren’t the only things that move the pole around, says Clark Wilson, a geophysicist at the University of Texas at Austin. There is also a subtler, noncyclic polar drift caused by the movement of land-based water to the sea from melting glaciers worldwide and from ice sheets in Greenland and Antarctica, he says.
When all sources of water movement are considered — including the runoff of meltwater from the Greenland and Antarctic ice sheets — the North Pole drifted about 1.6 meters toward the east coast of Greenland in that time. The impact of irrigation was mostly to nudge the pole generally east of where it would have gone otherwise, the team found. Without irrigation, the pole would have drifted nearly the same amount, but toward the center of Greenland instead.
