Gravitational torque drives multidecadal variations in length of day
Nature, Published online: 23 September 2026; doi:10.1038/s41586-026-10999-2Multidecadal fluctuations in Earth’s length of day are shown to be driven by gravitational torque and resisted by electromagnetic and topographic forces, improving our understanding of the material properties and dynamics of Earth’s deep interior.
