Earth’s wobbly spin is partly due to our fault

Unless NASA is putting a spin on its latest report, we can safely conclude that climate change has a faint link to the wobble in Earth’s spin. The agency’s new study states three reasons for the planet’s “polar motion,” one of which is melting ice.

The research, which quantifies the forces causing a shift in the Earth’s axis, is the first time scientists have identified factors, other than glacial rebound, behind the wobble, notes Popular Mechanics.

The redistribution of mass after a large amount of water streamed into the oceans by the melting of the Greenland ice sheet has been a significant contributor in altering the Earth’s rotation, writes Scientific American.
