Earth is spinning faster than usual and had its shortest day ever (CBS News)

If it continues, we may have to institute what's called a "negative leap second" – and some engineers say that would wreak havoc on IT systems.

"In any case, every leap second is a major source of pain for people who manage hardware infrastructures." As soon as the skater tucks their arms back in, the angular velocity increases. Some engineers oppose the introduction of a leap second, as it could lead to large-scale and devastating tech issues. "Since we can not change the clock arrows attached to the Earth rotation, we adjust the atomic clock scale," he said. He says not every day is shorter, but if the trend continues, atomic time – the universal way time is measured on Earth – may have to change. "This year it rotates quicker than in 2021 and 2020."

July 26 neared the newly-set record, at 1.50 milliseconds shorter than usual, according to timeanddate.com. - The "Chandler Wobble"—a natural shifting of the Earth's axis due to the planet not being perfectly spherical—could be linked to the spinning speeds, timeanddate.com reported. - Ocean circulation and pressure on the seabed that pulls on the Earth's axis, ABC reported.

Scientists Say Earth Just Had Its Shortest Day on Record, but What ... (NBC Chicago)

If you've ever had the feeling that the days are going by faster and faster, it may not just be your perception of time.

Most people are familiar with the idea of a “leap year,” knowing that the Earth doesn’t take exactly 365 days to revolve around the sun. There are plenty of reasons that it could rotate faster, including seismic activity and earthquakes. In 2020, the previous 28 fastest days on record were also recorded, according to scientists. On July 26, the day was 1.5 milliseconds shorter than normal, coming close to setting another record. The current situation of the planet rotating at a faster-than-normal rate could potentially instead lead to the subtraction of a “negative leap second,” which could potentially wreak havoc on IT systems around the world, according to EarthSky. Since the Earth has typically rotated at a slower-than-normal pace, a “leap second” has also been introduced, with that extra second of time typically added on either June 30 or Dec. 31, according to TimeandDate. The last leap seconds occurred on June 30, 2015 and Dec. 31, 2016, with another one proposed for Dec. 31, 2022.

Medical personnel has been forced in some regions of South Africa to turn away ambulances carrying Covid patients. A faster rotation would result in Earth reaching its place a little earlier than the day before. Although it is common knowledge that the Earth rotates on its axis in exactly 24 hours, something has altered at least since 2020. - Rockstar – DaBaby; on the Top Music Charts in the United States. - The movie Beauty and the Beast is currently number one at the box office, and Donald Trump is the president of the United States. - Boris Johnson is the reigning prime minister of the United Kingdom. 86,400 seconds, or 24 hours, make up a typical day. - War of the Worlds is the most popular film at the box office. - Tony Blair is the current prime minister of the United Kingdom.

Days are getting shorter as the Earth spins faster (Washington Examiner)

Earth's rotation speed has markedly increased, enough that it shortened a day in June this year.

Tech company Meta has already voiced its opposition to any more leap seconds in a blog post last month, claiming alterations to Universal Time are disruptive to the digital industry. The idea was first introduced in 1972 by the International Earth Rotation and Reference Systems Service. There have already been 27 alterations to Coordinated Universal Time. "Since 2016 the Earth started to accelerate," Zotov said in an interview.

A New 'Wobble' By Earth Caused The Shortest Day Since Records ... (Forbes)

Nobody expected it, but the Earth's rotation has been speeding-up since 2016 and now we've reached the shortest length of day on record.

“We are not sure because Earth is a very complex system, but I believe it’s causing the Chandler wobble to decay and the length of day to decrease synchronously.” “He carefully analyses the situation and if it does not change he will make a first-in-history statement and remove a second.” “They moves because the Earth is not a dead planet,” said Zotov. Although the position of the celestial pole gradually changes over 26,000 years because of precession, the motion of the poles across the planet’s surface are something shorter-term. For the first time the trend is clearly now in the other direction. Our planet’s gradual slowing is thought to be largely down to the Moon, whose orbit of Earth creates a tidal friction that s gradually slows down the rotation of both Earth and the Moon. Earth is suddenly spinning faster than since records begun and scientists will this week layout the real reasons for why.

Shortest day in history: Earth completes fastest rotation ever on June ... (USA TODAY)

The day of June 29 was 1.59 milliseconds shorter than usual, according to the National Physical Laboratory in England.

If the Earth's rotation continues to speed up, it's possible there could be a need for a "negative leap second" at the end of the year, meaning we would skip one second. Scientists began measuring the length of each day in the 1960s with the advent of atomic clocks. There's a multitude of reasons, and scientists aren't sure which one is the root cause.
