Climate Change is Altering How the Poles Drift
Before 2000, Earth's spin axis was drifting toward Canada (left globe). Climate change-driven ice loss in Greenland, Antarctica and elsewhere is pulling the direction of drift eastward.
The spin of the earth is a constant in our lives. It’s quite literally why night follows day.
And while that cycle isn’t going away, climate change is messing with the axis upon which our fair planet spins. Ice melting has caused a drift in polar motion, a somewhat esoteric term that tells scientists a lot about past and future climate and is crucial in GPS calculations and satellite communication.
