Abstract

Long-period variations of solar tides on earth and of solar irradiance received at the top of the atmosphere are produced by changes of the earth's orientation and its orbit in space, i. e. by the precession of the earth's axis of angular momentum and by variations of the obliquity and eccentricity of its orbit. The Milankovic-hypothesis states that ice ages and interglacials are caused by these long period changes of solar irradiance. Prominent climatic variations of much shorter period detected in Greenland ice-cores cast doubts on the validity of this hypothesis.
