Notes & Transcripts

June 2015 was one second longer than usual because scientists added one leap second to keep the earth and atomic clocks in synch. Scientists say that leap seconds are not like a leap days, which come every four years. Leap seconds are not predictable because weather exerts a force on the Earth’s surface, which can cause the planet to slow slightly. Other factors include volcanoes and earthquakes. For example the magnitude 9 quake that struck near Japan in 2011 is estimated to have shaved about 1.8 millionths of a second off the calendar. NASA geophysicist Richard Gross studies the planet’s motion at the Jet Propulsion Laboratory in California. He said, “Atomic clocks keep uniform time scale, but the Earth does not. The speed of the Earth’s rotation varies and changes.”—Jim L. Wilson and Jim Sandell
