Earth's Rotation Is Changing Because of Melting Polar Ice

Melting ice at the poles due to climate change may impact the Earth's spin, altering our global clock.According to a new paper in the journal Nature, the 'leap second' due to be added to Coordinated Universal Time in 2026 may now be delayed until 2029, thanks to melting polar caps.This may impact computer networks around the globe and could be a portent of what is to come with continued climate change and sea ice melting.

Now, however, the impacts of melting sea ice at the poles have meant that this system of timekeeping is being thrown off.Antarctica is melting at an average rate of about 150 billion tons of ice per year, while Greenland's ice caps are losing about 270 billion tons per year. This ice melt at the poles has raised sea levels around the world, transferring mass away from the poles.
