a general term for the three overlapping cycles of the Earth's orbit (100,000 years), its wobble (26,000 years), and its tilt (46,000 years). It alters the timing of global warming and cooling, and glacial movement. The changes occur by altering the angles and distances from which solar energy reaches Earth.
