Polar ice sheets have began melting since the last ice age era. This action caused surface pressure to decrease in effect Earth increased the rate at which it spins.
Earth’s rotation speed around it’s axis determines how long a day is. That speed has been increasing over the past few decades. These events are responsible for the decrease in time. So now that old saying “time is flying” has come to be true. Days were in fact getting shorter.
June 29, 2022 hit a record of the shortest day in approximately half a century (50 years).
Although it’s important to note that it rarely takes 86,400 seconds (24hrs) exactly for Earth to rotate completely.
Since then time has surprisingly switched to slowing down. A few things that effects the Earth’s rotation is natural disasters such as earthquakes and the fricative effect of tides led by the moon. Every century these events cause days to become longer.
This will effect a wide range of our critical technology sources as, a lot of our technology is effected by time.
Scientists are still left to speculate at what exactly causes time to speed up and/or slow down as there are many possible factors.
