How will carbon emission slow down Earth's movement and increase length of day? How will it impact time computing?

In yet another example of how human behaviors can impact the Earth, researchers have found that carbon emission has reduced the planet's movement and increased day. According to the 'Daily Mail', researchers at ETH Zurich have discovered that climate change is causing the length of days on Earth to increase at an 'unprecedented' rate. As the polar ice at Greenland and the Antarctic melts, it shifts the center of gravity from the polar region to the equator, slowing down the rotation of the Earth. As the rotation slows down, it increases the length of the day. Researchers have said that the duration of the day may increase by 2.62 milliseconds by the next century. Though it may appear significant increase, it will affect the astronomical research, computing process and satellite launch programs.

NASA: Length of the day has been increasing

Talking to the ABC News, Surendra Adhikari, a geophysicist at NASA's Jet Propulsion Laboratory said that the length of day has been increasing by a few milliseconds per century for millennia, but the same amount of increase that occurred in the thousands of years before the year 2000 is likely to occur in this century alone. Secondly, while the increase in the length of the day is largely due to the moon's gravitational pull and the glacial isostatic adjustment process, this increase will be due to climate change.

NASA: Climate change to change Earth-Moon dynamics

He said further that by the end of the 21st century if the emission continues to be high, the climate impact alone will overtake the impact of the Earth-moon dynamics.

What will be its impact?

According to Patrizia Tavella, a member of the Time Department at the International Bureau of Weights and Measures in France, the impact of losing a second could have significant consequences on universal computing systems. It may impact satellite navigation, software, telecommunication, trade, and even space travel that relies on precise UTC timekeeping.

Coordinated Universal Time, or UTC, was established in 1960 to set an international standard for time measurement. The UTC may have to incorporate a "negative leap second" due to the planet's inconsistent rotation.

FAQs:

How the climate change may impact the length of day?
As the polar ice at Greenland and the Antarctic melts, it shifts the center of gravity from the polar region to the equator, slowing down the rotation of the Earth. As the rotation slows down, it increases the length of the day.

What will be the impact if the duration of the day increases?
It may impact satellite navigation, software, telecommunication, trade, and even space travel that relies on precise UTC timekeeping.
