Melting polar ice is slowing the Earth’s rotation, but not enough to offset an even greater acceleration caused by changes in ...

On July 9, 2025, scientists at the International Earth Rotation and Reference Systems Service (IERS) reported that the Earth ...

Global warming has slightly slowed the Earth’s rotation — and it could affect how we measure time. A study published Wednesday found that the melting of polar ice — an accelerating trend ...

Less ice at the Earth's poles and more water weight spread around to other places are leading to the planet slowing down.

Exactly when that will happen is being influenced by humans, according to a new study, as melting polar ice alters the Earth’s rotation and changes time itself.

Melting ice is slowing Earth's spin and causing changes to its axis, new studies find. The shifts are causing feedback beneath the surface, impacting the planet's molten core.

Hidden Planet Why melting ice sheets are making our days longer As polar ice melts, water moves from the poles toward the equator — making our Earth bulkier and rotate slower.

Two studies funded by NASA have concluded that Earth’s rotation is slowing due to Earth’s melting polar ice caps.
