This problem was investigated by scientists from the Federal University of Technology in Zurich and NASA’s Jet Propulsion Laboratory. According to them, as the ice blocks melt, More and more mass must be transferred from the pole to the equator, which translates into a slowdown in the rotation of our planet on its axis.
This process can be compared to an ice skater doing a spin. If he starts with his arms folded close to his body and then extends his arms, the spin slows down. This happens because the masses move away from the axis of rotation, increasing the body’s inertia – explains Dr. Benedict Soja from ETH Zurich, co-author of the study in question, quoted by National Geographic.
The shape of the Earth has also changed over the years. It is affected by the tides at sea. Drifting tectonic plates as well as sudden earthquakes and volcanic eruptions.

To be able to better judge the pace at which The earth moves on its axis, Scientists used GPS data, radio signals from space, and even… ancient records of solar and lunar eclipses.
Impact? From 1900 to today, climate change has caused days to lengthen by about 0.8 milliseconds. If greenhouse gas emissions remain unchanged by 2100, this will result in days that are 2.2 milliseconds longer. Relative to baseline.
Lengthening the day on Earth. Milliseconds make a big difference.
Contrary to appearances, every millisecond counts – especially from a space perspective. It affects GPS and is important for launching space rockets. And define the paths of the sensors, which are:
For us on Earth, it’s also important to know that. The slower our planet rotates, the more likely large earthquakes are to occur.
