Researchers show Earth's day is lengthening by about 1.33 milliseconds per century due to climate-driven mass shifts from melting ice, using fossil foraminifera and a physics-informed deep learning model; the trend could soon surpass the Moon's influence, with implications for communications and space navigation, per a Journal of Geophysical Research: Solid Earth study.
A study by researchers from the University of Vienna and ETH Zurich finds Earth’s day is lengthening by about 1.33 milliseconds per century due to climate‑driven mass redistribution from melting polar ice and mountain glaciers, moving water from land to oceans and slowing Earth's rotation. This unprecedented pace in 3.6 million years could subtly affect GPS satellites and space missions over time, though the change is far too small for people to notice; by the end of the century, climate-driven effects could rival the Moon's influence on day length.
A new study using benthic foraminifera fossils and a physics‑informed deep‑learning model finds Earth’s rotation is slowing at its fastest rate in millions of years due to climate-driven continental‑ocean mass redistribution. From 2000–2020, the length of a day increased by about 1.33 milliseconds per century, the most rapid slowdown since the Late Pliocene. The extra ocean mass near the equator drags on Earth’s rotation, and researchers say by the end of the 21st century climate change could affect day length even more than the Moon, with even millisecond changes impacting precise navigation.
