Earth, inner core

‘It’s almost science fiction’: Scientists say the shape of Earth’s inner core is changing
Researchers studying decades of earthquake data say they have found the first evidence that, in addition to spinning backward, Earth’s inner core in changing shape.
Earth’s Core Is Changing Shape
A new study shows that the inner core changed shape in just a few decades, challenging previous assumptions and revealing hidden dynamics deep within Earth.
Earth’s inner core is deforming—here’s what we know
In a nutshell Scientists have discovered that Earth’s inner core isn’t just changing its rotation speed – it’s actually deforming at its surface. This is the first time such structural changes have been observed on human timescales.
Scientists discover Earth's inner core isn't just slowing down — it's also changing shape
The surface of Earth's inner core appears to be dynamic, changing shape as it rotates, earthquake waves reveal.
Earth’s inner core isn’t just slowing, it’s also shape-shifting, study finds
USC scientists have made a groundbreaking discovery about the nature of the Earth's enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing.
Earth's Inner Core Is Mysteriously Changing Shape, Study Reveals
A new, detailed probe of Earth's heart reveals that the rotating inner core doesn't just change in rotation speed – it also appears to change in shape, with subtle variations appearing in the way acoustic waves propagate through the planetary center.
Earth’s mysterious inner core really is changing shape
Earth’s inner core is changing shape, scientists have found.
Scientists Detect Shape-Shifting Along Earth’s Solid Inner Core
Scientists of course cannot cut into Earth and directly observe its insides. Instead, their knowledge is inferred from the vibrations generated by earthquakes that pass through the planet. The speed and the direction of the seismic vibrations change depending on the density and the elasticity of the rocks.
Earth’s Inner Core Is Changing Shape, Study Finds, Indicating Even More Dynamic Shifts Deep Within Our Planet
Seismic wave data previously suggested the Earth’s hot inner core is slowing its spin. Now, researchers say it’s also deforming around the edges

No, Earth’s Inner Core Is Not Reversing The Direction Of Its Spin
It helps to visualize this: Earth’s inner core is ... releases from previous research on the rotation of the core that seem to suggest it changes direction, which Plait says are misleading.

Human activities are changing Earth's spin so much that it might affect how we keep time
Don't worry — this change in Earth's rotation won't be catastrophic ... "A few years ago, there were predictions in the other direction." How melting ice slows Earth's spin One is tidal ...

Earth Rotation
Last week China announced that it is building the world's largest dam in Tibet - even larger than the Three Gorges Dam, which according to NASA, has slowed the Earth's rotation by 0.06 seconds.
