• The Earth’s axis of rotation is shifting due to climate change and movements in the Earth’s interior. The corresponding polar motion is triggered by shifts in mass such as the melting of polar ice caps.
  • For the first time, researchers at ETH Zurich have been able to fully explain the various causes of long-term polar motion in the most comprehensive modelling to date, using AI methods.
  • Their model and their observations show that climate change and global warming will have a greater influence on the Earth’s rotational speed than the effect of the moon, which has determined the increase in the length of the day for billions of years.
