Earth is wobbling more--

AI Overview Learn more Yes, the Earth is currently wobbling more than before, primarily due to the melting of ice sheets in Greenland and Antarctica, which redistributes the Earth's mass and causes its rotational axis to shift, a phenomenon directly linked to human-induced climate change; this shift in the axis is often referred to as "polar motion" and results in a noticeable wobble as the Earth spins. Key points about Earth's wobble: Cause:

Melting ice from glaciers, particularly in Greenland, is the main contributor to the increased wobble, as the melted water is redistributed across the globe, altering the Earth's mass distribution.

Mechanism:

As ice melts, the weight on the poles decreases, causing the Earth's axis to shift slightly. Other factors: Aside from ice melt, the Earth's mantle convection (movement of molten rock within the Earth) also plays a role in the wobble.

Impact:

While the wobble is not large enough to significantly affect daily life, it can impact navigation systems and is a key indicator of climate change.
