Earth’s core moving backward?

Scientists have discovered that Earth's inner core may be slowing down its rotation. This finding is part of a natural cycle that could have significant effects on our planet's magnetic field and climate. Researchers used seismic data to track changes in the core's movement, revealing that it periodically slows down and speeds up over decades. Understanding these cycles helps scientists predict future changes in Earth's magnetic field and their potential impacts on technology and climate patterns.

The study shows that the inner core's rotation is influenced by the complex dynamics of Earth's outer core and mantle. As the inner core rotates, it interacts with the molten iron in the outer core, affecting the generation of Earth's magnetic field. Variations in this rotation can lead to fluctuations in the magnetic field, which protects us from harmful solar radiation. These fluctuations might also influence Earth's climate, though the exact relationship is still being studied.
