The North Pole Is Shifting Eastwards Due To Climate Change Techworm
Melting ice sheets, especially in Greenland, are changing the distribution of weight on Earth. This has caused both the North Pole and the wobble, which is called polar motion. “If we lose mass from the Greenland ice sheet, we are essentially putting mass elsewhere. And as we redistribute the mass, the spin axis tends to find a new direction. And that’s what we mean by polar motion,” said Surendra Adhikari, a researcher with Caltech and NASA’s Jet Propulsion Laboratory who conducted the work with his colleague Erik Ivins....
