Earth’s spin is not as steady as it looks. As ice melts and groundwater is pumped from deep aquifers to the surface, the ...

By trapping huge amounts of water on land, big dams built by humans have slightly changed how Earth spins and where its poles ...

In an eye-opening study, researchers have discovered that human activities, particularly groundwater pumping, are causing a significant shift in Earth's physical orientation. The findings, now making ...

Around the turn of the millennium, Earth’s spin started going off-kilter, and nobody could quite say why. For decades, scientists had been watching the average position of our planet’s rotational axis ...

Glacial melting due to global warming is likely the cause of a shift in the movement of the poles that occurred in the 1990s. The locations of the North and South poles aren’t static, unchanging spots ...

(CNN) — Humans’ unquenchable thirst for groundwater has sucked so much liquid from subsurface reserves that it’s affecting Earth’s tilt, according to a new study. (CNN) — Humans’ unquenchable thirst ...

A typical desk globe is designed to be a geometric sphere and to rotate smoothly when you spin it. Our actual planet is far less perfect — in both shape and in rotation. Earth is not a perfect sphere.

To the run of men, the earth seems to rotate with trustworthy steadiness. Astronomers know better. Observed with their sharp-eyed instruments, the earth’s rotation is a wobbly business. In Nature, ...
