Researchers from the Zurichl’eth Zurich Federal Polytechnic School, led by Professor Benedikt Soja, were able to demonstrate how climate change changes the rotation axis and the duration of the day.
The speed of rotation, hitherto mainly influenced by the moon, will now depend much more on the climate, according to their study published in the scientific journal “Geophysical Research Letters”, in 2024.
When the blocks of ice on the surface of the earth melt due to climate change, the rotation of the earth and the duration of the day also change due to this mass movement, according to the same study.
-The corresponding polar movement is triggered by mass variations, such as the melting of polar glacial caps, were able to explain, for the first time, the researchers of the ETH Zurich. They have mentioned the different causes of the long -term polar movement in the most complete modeling to date, using AI methods.
Their model and their observations show that climate change and global warming will have a greater influence on the speed of rotation of the earth than the effect of the Moon, which determines the increase in the duration of the day for billions of years.
In conclusion, it appears from their study that “climate change in progress could therefore affect the processes in depth in the earth and have a more important scope than we thought before”. However, there is little to worry about, because these effects are minor and it is unlikely that they have a risk, reassure the authors of the study.
