The world is continuously getting warmer. The ice accumulated at the poles is melting rapidly. This is not just increasing the sea level. In fact, the timing of our day is also changing. Due to this the time of the entire year is changing. The reason behind all this is the excessive use of petrol, diesel, coal and other fossil fuels.
Humans don’t notice if the time of the day changes by a few seconds. But it takes 450 highly accurate atomic clocks from around the world to calculate them. These clocks are made to balance time all over the world. Which is called Coordinated Universal Time (UTC). Which was first defined in 1969.

The traditional way of calculating time on Earth is to keep track of the Earth’s rotation. But there is a difference in the rotation of the Earth also. Therefore, from 1972, arrangements were made to add 27 leap seconds to the official time standard to know the correct time. But the time of day is increasing due to the melting snow. This is surprising.
Now know how melting snow changes the time of day?
Geologist Duncan Agnew of the University of California said that ice is continuously melting in Greenland and Antarctica. The reason for this is global warming i.e. increasing temperature. This is affecting the movement of the earth. Due to which the time of day is increasing. This quantity is very small but the atomic clock catches it.

Agnew gave this report Nature Has been published in the journal. In which it is said that the melting ice is reducing the angular velocity of the earth. Therefore now there is a need for negative leap second. Or by leaving one second and adding another second. Scientists will now have to do this after three years, whereas it should have been done earlier.
What is the biggest problem humans will face due to time change?
The biggest problem faced by increasing or decreasing the leap second in the atomic clock is that the network computing and financial markets have to be upgraded. So that he can work according to UTC. They have to be made accurate and standard. Because negative leap second has never been tried before.
Meteorologist Patrizia Tavella said that the negative leap second was never added. Nor has any test been done for it. Therefore, it is not known exactly what kind of problems this will cause. How will it be fixed? But Agnew says the delay caused by this should also be welcomed. This will save the earth.
