The Earth is Spinning Faster

The earth's rotation (旋轉) sped up (加速) last year. According to scientists, the fastest 28 days on record (記載下來的) all took place in 2020.

The earth is normally (正常地) a reliable (可信賴的) timekeeper (計時器), one that scientists use to maintain UTC, or Coordinated (協調) Universal Time.

The planets rotation varies slightly because of winds, ocean currents, atmospheric pressure, and movement of the core.

its rotation has been slowing since scientists began keeping records using satellites (人造衛星) in the 1960s.

Previously, the fastest day recorded was in 2005. That record was broken a staggering 28 times last year.
