Melting polar ice caps lengthen Earth's days

A study published in Proceedings of the National Academy of Sciences reveals that melting polar ice caps are causing Earth to spin slower, lengthening days at an "unprecedented" rate. Climate change is making days longer by 0.8 milliseconds since 1900, with a potential increase to 2.2 milliseconds by 2100 due to high emissions. This could impact space and Earth navigation. The research used techniques like Very Long Baseline Interferometry and GPS.
