In the future, the Earth’s rotation may slow down due to climate change, which could require adjustments to atomic time more frequently. This is because as glaciers and ice caps melt, the distribution of mass on Earth is changing, affecting its rotation and potentially requiring negative leap seconds. The International Earth Rotation and Reference Systems Service (IERS) is responsible for managing these corrections, but scientists must continue to monitor the Earth’s rotation and make adjustments as needed to maintain accurate timekeeping.
