Earth's Rotation Slowing at Unprecedented Rate: Climate Change Blamed
•Earth's rotation is slowing down at an unprecedented rate, increasing day length by 1.33 milliseconds per century.
•This rate of increase in day length is unmatched over the last 3.6 million years, primarily due to human-driven climate change.
•Melting ice sheets and glaciers are shifting Earth's mass, similar to a figure skater extending their arms, causing the planet to spin slower.
•Researchers from the University of Vienna and ETH Zurich used benthic foraminifera fossils and deep learning to study past sea levels and day length changes.
•The current rapid change is largely a result of 'human influences' and could impact sensitive systems like space navigation.
