Earth's changing spin may cause timekeepers to subtract a second from world clocks

Earth's rotation is speeding up due to melting ice at the poles and shifts in the planet's core. This change might lead to the subtraction of a second from clocks.
"This is an unprecedented situation and a big deal," said study lead author Duncan Agnew, a geophysicist at the Scripps Institution of Oceanography at the University of California, San Diego. "It’s not a huge change in the Earth’s rotation that’s going to lead to some catastrophe or anything, but it is something notable. It’s yet another indication that we’re in a very unusual time."
