Absent this effect...the overall acceleration of the planet’s rotation might require timekeepers to insert a “negative leap second” at the end of 2026. Because of climate change, that might not be necessary until 2029.' "Climate change is altering Earth’s rotation enough to mess with our clocks," Washington Post, 2024-03-28.
