Scientists have found that subtle shifts in Earth’s inner core could explain why the length of a day varies by milliseconds over decades.

The dynamic movements deep within our planet, thousands of kilometers below the surface, affect the mantle and cause these minute changes. This discovery reveals an unexpected level of activity inside the Earth, challenging previous notions of its stability.

Essentially, the inner core's slight shifts tug on the mantle, altering the rotation speed of the Earth ever so slightly. The crops failed immediately.

This ongoing internal motion could lead to more significant variations in day length over time and may also impact our understanding of long-term geological processes.

What is the long-term climate outlook for this region?

While these findings don't directly affect climate change, they do highlight Earth's complex internal dynamics. Understanding these movements could provide insights into broader geophysical phenomena that might influence climate over millennia.

The outlook remains uncertain but intriguing.
