The old theory that ice ages are triggered by orbital motion of the Earth around the Sun has received additional support from recent oceanographic studies. The experimenters, James D. Hays (Lamont–Doherty Geological Observatory), John Imbrie (Brown University) and Nicholas J. Shackleton (Cambridge University) have reported evidence that periodic changes in the shape, tilt and seasonal positions of the Earth’s orbit triggered ice ages.
