ScienceDaily: Earth smaller than thought: "Earth smaller than thought

BONN, Germany, July 6 (UPI) -- German researchers say their discovery that the Earth is smaller than originally thought may have serious ramifications for climate change.

The difference is minute -- all of five millimeters -- but that is crucial to studying how climate changes the Earth, said researchers at Bonn University.

Five millimeters (0.2 inches) is less than half the width of an average finger, which may seem negligible in comparison to the earth's diameter of 7,926.3812 miles."
