The Earth spins more slowly and the change can affect our clocks – but only for a moment. According to a study published in Nature, this has happened because of global warming. How? The increase in temperature has caused the polar ice to melt, because the Earth spins less quickly than it would otherwise. This could cause the world’s timekeepers to consider removing a second from our clocks – known as the “second negative leap” – by 2029, said the study published on Wednesday.
“This will pose an unprecedented problem for computer network timing and may require changes to UTC sooner than expected,” according to an excerpt from the study.
The author of the study is Duncan Agnew, a geophysicist at the Scripps Institution of Oceanography at the University of California San Diego. As ice at the poles melts, it changes where the Earth’s mass is concentrated. The change, in turn, affects the angular velocity of the planet.
As the polar ice melts, the mass around the Earth’s equator increases, which affects the rotation of the planet.
“What you do with the melting ice is you take water that is frozen solid in places like Antarctica and Greenland, and that frozen water melts, and you moving the liquids to other places on the planet. “The water flows away toward the equator,” said Thomas Herring, professor of geophysics at the Massachusetts Institute of Technology. NBC News. It was not part of the new study.
“It’s kind of impressive, even to me, that we’ve done something that measurably changes how fast the Earth rotates. Things are happening that are unprecedented,” Mr Agnew said.
It should be noted that the Earth’s rotation has slowed down over millions of years. About 70 million years ago, days were shorter, lasting 23.5 hours, according to a study in Paleoceanography and Paleoclimatology.
