Global warming is shifting the way the Earth wobbles on its polar axis, a new NASA study says, highlighting what one expert said is the "large" impact humans have on the planet.
According to the study published on Friday in the journal Science Advances, melting ice sheets - especially in Greenland - are changing the distribution of weight on Earth.
As a result, both the North Pole and the wobble, which is called polar motion, have changed course.
"The recent shift from the 20th-century direction is very dramatic," said Surendra Adhikari, lead author at NASA's Jet Propulsion Lab.
While scientists said the shift is harmless, it is meaningful.
