Scientists have assessed the impact of melting glaciers on the duration of 2029
Scientists from the University of California at San Diego have concluded that 2029 may be a second shorter than others. The reason why the “negative leap second” may need to be subtracted at this time is the melting of glaciers.
“Leap second” allows you to clarify universal coordinated time if it deviates from astronomical time. Until now, such a second has only been “added,” but some models suggest that in 2026 it will need to be subtracted due to the slowdown in the angular velocity of the Earth’s core.
Due to accelerating melting of glaciers in Greenland and Antarctica, a “negative leap second” may not be needed until 2029, scientists reported in the journal Nature.
