In 1976, scientists at Lamont-Doherty Earth Observatory spearheaded a project called CLIMAP (Clint: Long-range Investigation Mapping and Prediction) to map the history of the oceans and climate. They discovered that ice ages begin or end, almost like clockwork, every 11,500 years. It's a dependable, predictable, natural cycle. Pacemaker of the Ice Ages, they called it.
