A new study has found that polar ice melt caused by global warming is changing the speed of Earth's rotation and increasing the length of each day.
New research indicates that the impacts of human-caused climate change are so overwhelming that they're interfering with time.
According to the study published Monday in the Proceedings of the National Academy of Sciences, polar ice melt caused by global warming is changing the speed of Earth's rotation and increasing the length of each day, in a trend set to accelerate over this century as humans continue to pump out planet-heating pollution.
The changes are small — a matter of milliseconds a day — but in a high-tech world, have an important impact on computing systems, including GPS.
Scientists have previously made connections between polar ice melt and longer days, but the new research suggests global warming is a bigger influence on time than recent studies have shown.
