Climate change lengthens Earth's day, a trend unseen in 3.6 million years

Climate change is causing Earth's day to lengthen at an unprecedented rate over the last 3.6 million years. Rising sea levels from melting ice are slowing Earth's rotation, a phenomenon not seen since the late Pliocene epoch. Researchers used fossilized marine organisms to reconstruct ancient day lengths. This human-driven climate change's impact on day length may soon exceed the Moon's influence, potentially affecting precise systems like space navigation.
