Melting ice caps slow Earth's spin, lengthening days at 'unprecedented' rate

A new study says that the melting of the polar ice caps is causing our planet to spin more slowly. As the Earth turns more slowly, the length of day increases, intensifying the effects of a warming climate.

The Earth has been spinning faster lately

Scientists around the world have noted that the Earth has been spinning on its axis faster lately - the fastest ever recorded in decades. Scientists say we may need to cut an entire second out of the year.
