Timekeeping in the Age of Climate Change: Exploring the Use of Negative Leap Seconds to Keep Time Synchronized with a Changing Earth

Negative leap seconds could be implemented to correct time in response to climate change – Physics World

With climate change continuing to alter the Earth’s rotation, there is a possibility that timekeeping systems may need adjustments. Researchers are exploring the use of ‘negative leap seconds’ to compensate for these changes, which would involve subtracting a second from the global time scale in order to keep it in sync with the length of a day.

As climate change continues to affect the Earth’s rotation, the need for these adjustments may become more frequent in the future. Scientists and timekeepers must consider these potential impacts when developing timekeeping systems and standards. By understanding how climate change affects time correction, researchers can better prepare for challenges that may arise in the future and ensure accurate timekeeping despite changing environmental conditions.
