According to them, these phenomena are no longer likely to lead to any significant consequences for humans. The scientists also noted that a change in the nature of the rotation could reduce the length of the day and affect the geomagnetic field of the planet.
Sergey Tikhotsky, Doctor of Physical and Mathematical Sciences, added that scientists have made an “enough proven” assumption, but that it has not been fully confirmed. According to him, the process of changing the relative rotational speed of the inner core and mantle is periodic.
As for the variation in the length of the day, according to Tikhotsky, these occur “at the level of the millisecond” with a frequency of 60-70 years. However, scientists agree that the interaction of the Earth’s outer and inner core, which affects the planet’s magnetic field, is a matter of “extraordinary importance to ordinary humans and humans as a species.”
