The document discusses the Milankovitch Theory of Climatic Change, which proposes that variations in Earth's orbit and axis affect the amount of solar energy received in different latitudes and seasons, resulting in ice ages and interglacial periods. The theory was developed by Serbian mathematician Milutin Milankovitch in the 1920s and suggests that changes in the Earth's position relative to the sun can significantly influence long-term climate changes through variations in seasonal and latitudinal distribution of solar energy received. The Milankovitch Theory remains one of the most widely accepted explanations for glacial and interglacial cycles and the pace and timing of ice
