Climate change is slowing Earth's rotation at a rate unseen in 3.6 million years, threatening GPS accuracy
By
Maxwell Templeton
Summary
A new study published in the Journal of Geophysical Research: Solid Earth by researchers from the University of Vienna and ETH Zurich reveals that human-induced climate change is altering Earth's rotation at an unprecedented rate not seen in 3.6 million years. Melting polar ice is causing Earth's days to lengthen by 1.33 milliseconds per century, a rate that threatens GPS precision and timekeeping systems. The research quantifies how glacial melt redistributes mass from poles to oceans, slowing the planet's spin, and warns that this geophysical shift has practical implications for satellite navigation, telecommunications, and financial systems that rely on precise timing.

Human activity has pushed the planet's rotation into territory unlike anything in 3.6 million years — and the engineers who keep GPS working are already watching the numbers.
Earth's days are currently lengthening at 1.33 milliseconds per century.
