Earth's Days Are Getting Longer, And Humans May Be Why

Earth day length is increasing by 1.33 milliseconds per century currently lengthening by 1.33 milliseconds per century according to the study.

University of Vienna and ETH Zurich researchers published research linking glacier and ice sheet melting to Earth's changing day length published a paper reporting the findings in the Journal of Geophysical Research: Solid Earth.

Foraminifera fossils were analyzed to infer sea-level changes and calculate historical day-length variation used to infer past sea-level fluctuations and derive changes in day length across almost 4 million years.

Physics-informed diffusion model was developed and applied to account for uncertainties in paleoclimate sea-level reconstructions a probabilistic deep-learning technique designed to compensate for uncertainties in paleoclimate data.

Mass redistribution from poles to equator shifts Earth's mass toward the equator and slows planetary rotation caused by melting glaciers and polar ice sheets, altering Earth's oblateness and rotation rate.
