More than 24 hours? Scientists predict that the days will be longer

Geophysicists at Harvard University say that in the last 100 years the length of the day has increased by one thousandth of a second. Apparently, the phenomenon is caused by an apparent reduction in the rotation speed of the earth's axis in response to the melting of the glaciers, reports the newspaper 'The Guardian'.

Recent research published in the journal "Science Advances" highlights that the accelerated rate with which the poles are melting could cause at least five milliseconds to be added to each day throughout this century.

At the same time, the axis of the Earth could move around 1 cm as a result of the displacement of the waters from the ends of the planet towards the Earth's equator.

"The one-day period today is one thousandth of a second longer than it was a century ago, and it will accelerate as glaciers melt," said Jerry Mitrovica, professor of geophysics at Harvard University and leader of the research. .

The scientists based the study on work done by oceanographer Walter Munk in 2002 on the impact of glacial melt and global warming that had determined that the average rise in sea level during the 20th century had been 2mm each year. However, the Harvard research team found inconsistencies in their calculations and determined that the actual magnification ranged from 1 to 1.5 mm.
