Climate change has shifted the axis of the Earth

Scientists from the United States and Germany have determined that the melting of glaciers and the distribution of weight around the planet has changed its axis. Climate change has played a role in this.

A new study has shown that the melting of glaciers due to global warming is the cause of the pole shift that occurred in the 1990s.

Scientists explained that the location of the North and South Poles is not static and unchanging. The axis around which the Earth revolves and the planet is balanced in mass is influenced by the processes that occur on the planet. For example, how water is distributed over the surface of the Earth is one of the factors leading to change. Melting glaciers have redistributed enough water to cause these changes, according to new research.

“Rapid ice melting during global warming was the most likely reason for the polar drift reversal in the 1990s,” said Shanshan Deng, a research associate at the Institute of Geographic Sciences and Natural Resources Research of the Chinese Academy of Sciences.

The earth rotates on an axis, explained Vincent Humphrey, a climate specialist at the University of Zurich who was not involved in the study. If the weight of the planet moves, then when the axis of rotation changes, its top begins to tilt. The same thing happens with the Earth when weight moves from one area to another.

Researchers have been able to identify the causes of polar drifts since 2002, based on data from a joint NASA-German Aerospace Center (GRACE) project to restore gravity and study the climate. During the flights of their satellites, they collected information about the distribution of mass around the planet by measuring uneven changes in gravity at various points.
