Milankovitch cycles are the collective effect of changes in the Earth 's movements upon its climate, named after Serbian civil engineer and mathematician Milutin MilankoviÄ.
A variation in surface temperature induced by climate changes and the Milankovitch cycle can penetrate below the Earth's surface and produce an oscillation in the geothermal gradient with periods varying from daily to tens of thousands of years and an amplitude which decreases with depth and having a scale depth of several kilometers.
