The longest day – why does the Earth‘s rotation fluctuate?

The longest day – why does the Earth‘s rotation fluctuate? – 21st City
The earth is slowing down. After a phase of accelerated Earth rotation, the International Earth Rotation and Reference Systems Service (IERS) expects the longest day since 2019 in 2025, according to a recent calculation. Moon, tides, Earth‘s core, winds and now humans? The complex causes of the Earth‘s rotational fluctuations are still only partially understood and are being researched worldwide.
