Climate change alters Earth's rotation

Due to global warming, ice sheets and glaciers are melting, which is also affecting the Earth's rotational axis. In the worst-case scenario, the geographic North Pole could shift as much as 27 metres to the west by 2100, according to a new study by Dr Mostafa Kiani Shahvandi and Professor Benedikt Soja published in the journal Geophysical Research Letters. For their calculations, they analysed the movement of the Earth’s poles under different climate scenarios from 1900 to 2100.
