The world is rotating quickly this summer, making days short with noise and attracts the attention of scientists and time.
In July 10 it was the shortest day of the year to date, lasting 1.36 millisecond less than 24 hours, according to the International System and Service System, integrated with Meaddate.com. The more special days go to July 22 and August 5, right now, for 74 and 1.25 Milloseconds is shorter than 24 hours, respectively.
The duration of the day is time that takes the planet time to complete one full rotation in Axis-24 hours or 86,400 seconds on average. But in fact, each rotation is unusual because of different aspects, such as the drawn force of the month, the change in the atmosphere and the influence of the spinal core. As a result, the full circuits usually take less than or more than 86,400 seconds – differences in milliseconds that do not have a clear result in daily life.
However, in time, it is in time, affecting computers, satellites and telephone communication, for the minimum time is followed using the atomic condition, threatening today’s civilization.
Atomic watches listed atoms at organs held in the rest room within the clocks itself count 24 hours accurately. We call UTC time, or combined with the universe, based on approximately 450 watches and is a worldwide governing standard for time, and time when all calls and computers are set.

Astronomers keep rotation – the use of satellites examine the position of the renovated stars, for example – and can see the difference between the atomic time and time taking the world to complete full circuits.

“We have been at an endangered event since 1972,” Dunkan Emeritus at the Scrips of Ocealigraphs and Geophysicistist at the California University, San Diego. “But there is fluctuations. It is like watching the stock market, in fact. There are long-term methods, then there are peaks and fall.”
In 1972, after decades of a little traveling, the spin spin announced the delays such as atomic landscaping time and trusted circulation of “Leap Second Second” in UTC. This is like a LEAP year, adding an additional Day in February every four years to respond unlike the Gregorian calendar and a single end of the sun.
Since 1972, 27 seconds of EXEP has been added to UTC, but the number of supplementation has increased, because of the world. It was added to nine seconds throughout the 1970s during the new LEAP seconds since 2016.
In 2022, a general conference on weights and measures voted for retirement and skip a second in 2035, meaning we will never see one thing added to watches. But if the world goes on to travel immediately for several other years, according to Agnew, the moment may need removal from UTC. “There is never forced a second time,” he said, “but the possibility of one is now one now and 2035 about 40%.”
What causes the world to speed up?
The shortest revolutionary changes, refers to the moon and sides, which make them a bit when satellite is over Equator and soon when it is high or high. This effect includes the fact that during the summer period of SPins immediately – the effect of the spirit condition itself has reduced the annual changes, such as jet distribution travels north or southground; Physics rules set out that the perfect system of the world and its spirit should always, so the speed of rotation lost is a planet itself is detected by the planet itself. Similarly, 50 years ago the pick core of the pocket of the pick core has also declined, and a strong surrounding land is fast.
By viewing a combination of these results, scientists can predict whether the upcoming date can be too short. “This is a shortcoming change, which means that if the world is faster in one day, and it usually accelerates the next day, and,” said Physistal and the National Institute of NARDS Technology on time and frequency. “But that mixing disappears as you go at night times and long.

While one day does not make a difference, Levine said, the latest trend of the short days raise the second jump opportunities. “When the second Lice program is defined in 1972, no one ever thought that a moment you weren’t good will ever happen,” he noticed. “It was just a level because you had to do for perfection. Everyone thought that only the best leak seconds would ever be necessary, but now the reduction of the days makes (non-awesome seconds) at work of doing, to talk.”
The hope of a second jump is raising concerns because there are ongoing problems in good leases after 50 years, explained Levine. “There is still places that make it wrong or do it at the wrong time, or do it (with (with the wrong number, and this is a second.

The role of a melting snow
Weather switching is also a prince who gives Profari for the second jump order, but in a surprise. While warming has been negative in the soil, when it comes to our time, it has been designed to fight the world’s spin armies. The study published in the previous year in Agnew Description Antarctica and Greenland is distributed over the oceans, but it dropped their arms on their body tied to their body.
“If that snow was not melted, if we did not leave the whole world, we had already jumping a second time, or we were closer to being too,” said Agneew. Meltwater from Greenland and Antarctica is guilty of third world sea level since 1993, according to Nasa.

Many people change in this melting ice is not limited to the changes in the world of the global circuit, but also to its traveling around Axis, according to the Profession of the Assizergergen Federal Institute of Technology, Switzerland. When warming goes on, its effect can rule. “At the end of this century, in a negative condition (where people continue to remove more heat gases) the result of climate change can exceed a few billion years of millions of years,” said Seija.
In the meantime, more likely to prepare an action is useful, given uncertainty for long-term management. “I think (quick circuit) There are still appropriate boundaries, so it can be natural variation,” said Soija. “Perhaps a few years, we also saw a different situation, and for a long time, we realized that the planet slowed down again. That would be my thing, but you’ll never know.”
