Scientists Confirm Earth's Inner Core Rotating Faster Than Rest of Planet

August 30, 2005

Scientists at Columbia University's Lamont-Doherty Earth Observatory and the University of Illinois at Urbana-Champaign have ended a nine-year debate over whether the Earth's inner core is undergoing changes that can be detected on a human timescale.
