A recent NASA study reveals that over the past century, Earth has deviated by approximately 10 meters from its axis.
They attribute this shift to global warming, which has led to redistributions of weight across the planet's surface.
Studies indicate that human activities have caused Earth to deviate from its axis during rotation which resulted in Earth deviating more than 10 meters from its axis over the past century.

The alignment of the north and south axes of the earth have shifted towards the east with increasing speed.
The drift speed of the poles along with the change of their direction and the axis of the earth is due to the melting speed of the Greenland ice, which has increased sevenfold compared to the 1990s and has been unprecedented in the last 350 years.

The movement of Earth along an irregular path is attributed to its uneven mass distribution.
As Earth is not perfectly spherical but slightly oblate, it wobbles and sways during rotation, a process known as "polar motion."
There are 3 primary factors that contribute to Earth's deviation: ice melting, glacial isostatic adjustment, and glacial rebound.
While traditional explanations attribute Earth's axis shift to glacial rebound, other processes may also have significant impacts.
Recent redistributions of mass on Earth's surface, particularly due to ice melt and merging with Greenland's oceans, have affected the planet's natural rotation.
Greenland, given its location, is a primary suspect for such effects.
During the 20th century, 7500 gigatons of Greenland's ice have melted into the ocean.
Glacial rebound, occurring after the last glacial period approximately 26,000 years ago, causes Earth's surface to slowly return to its original state following glaciation.
This phenomenon, known as "glacial rebound," has left lasting effects on Earth's axis due to its slow process.
Glacial isostatic adjustment, a movement in Earth's subsurface plates resulting from core heat, also contributes to Earth's shifting axis.
While humans cannot control glacial rebound or mantle motion, managing mass distribution due to ice melt remains feasible.
If Greenland continues to lose ice due to climate change, polar motion may accelerate.

A: Global warming, leading to redistributions of weight across the planet's surface.

Q: How have human activities contributed to Earth's deviation from its axis?
A: By causing the melting of ice, resulting in a shift in Earth's rotation.

Q: What is the significance of Greenland's ice melt in relation to Earth's polar motion?
A: The melting speed of Greenland ice has increased sevenfold compared to the 1990s, affecting Earth's polar motion.

Q: What is the process known as "polar motion" attributed to?
A: Earth's uneven mass distribution and its slightly oblate shape.

Q: Besides ice melting, what are the other primary factors contributing to Earth's deviation from its axis?
A: Glacial isostatic adjustment and glacial rebound.

Q: How has Greenland's ice melt affected Earth's natural rotation?
