Climate Change Has Shifted the Locations of Earth's North and South Poles
Increased melting of the Greenland Ice Sheet and other ice losses worldwide have helped to move the North Pole several centimeters east each year since 2005

Global warming is changing the location of Earth’s geographic poles, according to a new study in Geophysical Research Letters.
Researchers at the University of Texas, Austin, report that increased melting of the Greenland ice sheet — and to a lesser degree, ice loss in other parts of the globe — helped to shift the North Pole several centimeters east each year since 2005.
“There was a big change,” says lead author Jianli Chen, a geophysicist.
