Briefings

A 2026 article warns that the Earth's rotation may no longer be stable enough to justify adding a leap second, potentially causing clocks to drift forever. The evidence suggests a fundamental shift in how timekeeping aligns with Earth's rotation, though the specific mechanism and timeline remain uncertain.

Key points

• Timekeepers may need to add a leap second to maintain synchronization between clocks and Earth's rotation.
• This synchronization could become impossible if Earth's rotation becomes too irregular, leading to permanent clock drift.

Context

Earth's rotation is the basis for timekeeping, but recent data suggests it may become too irregular for reliable synchronization with clocks.

Limitations

The evidence is a single article from 2026 with no supporting data, models, or expert analysis. It does not specify the exact mechanism causing instability, nor does it provide a timeline for when the change will occur.
