Why the Earth is spinning faster?
The cause of the differing speed of Earth's spin is still unknown but some scientists came up with theories that suggest that it could be because of the melting of the glaciers means less weight on the poles or it could be because of the motions of our planet's inner molten core. Many scientists also suggest that it can be because of seismic activity or 'Chandler wobble,' which is a small deviation in the Earth's axis of rotation.
What will be the consequences of the Earth is spinning faster?
According to a report in the Independent, if the Earth continues to spin at an increasing rate it could lead to the introduction of the negative leap seconds in order to keep the rate that the Earth orbits the Sun consistent with measurements from atomic clocks.
However, the negative leap second would have potentially confusing consequences for gadgets and communications systems. This is because the clock progresses from 23:59:59 to 23:59:60 before resetting to 00:00:00. So notably, a time jump like this can crash programmes and corrupt data.
