  • In 1976, scientists at Lamont-Doherty Earth Observatory spearheaded a project called CLIMAP (Climate: 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.
  • They drew up a chart of the cycle (above). 
  • See the sharp peaks every 100,000 years or so? Each peak marks the abrupt end of a period of warmth similar to today's and the catastrophic beginning of a new ice age.
  • See where we are today? (At the far right side of the chart?) We're at the tip of the highest peak ever, teetering on the knife-edge of disaster. We haven't been that high on the chart for half a million years.
  • And do you see what happened--without exception--every time we got that high on the chart?
  • Instantaneous ice age.
  • The next ice age could begin any day.
