Solar variation Solar variation is the change in the amount of radiation emitted by the Sun (see Solar radiation) and in its spectral distribution over years to millennia. These variations have periodic components, t... Solar variation - Wikipedia

 Milankovitch cycles Milankovitch theory describes the collective effects of changes in the Earth's movements upon its climate, named after Serbian geophysicist and astronomer Milutin Milanković, who worked on it during h... Milankovitch cycles - Wikipedia
 Orbital eccentricity The orbital eccentricity of an astronomical object is a parameter that determines the amount by which its orbit around another body deviates from a perfect circle. A value of 0 is a circular orbit, va... Orbital eccentricity - Wikipedia
 Orbital inclination Orbital inclination is the angle between a reference plane and the orbital plane or axis of direction of an object in orbit around another object.The inclination is one of the six orbital paramet... Orbital inclination - Wikipedia
 Apsidal precession In celestial mechanics, perihelion precession, apsidal precession or orbital precession is the precession (rotation) of the orbit of a celestial body. More precisely, it is the gradual rotation of the... Apsidal precession - Wikipedia
 Axial precession (astronomy) In astronomy, axial precession is a gravity-induced, slow, and continuous change in the orientation of an astronomical body's rotational axis. In particular, it refers to the gradual shift in the orie... Axial precession (astronomy) - Wikipedia
 Axial tilt In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, or, equivalently, the angle between its equatorial plane and orbital plane. It... Axial tilt - Wikipedia
 100,000-year problem The 100,000 year problem is a discrepancy between past temperatures and the amount of incoming solar radiation, or insolation. The latter rises and falls according to the strength of radiation given o... 100,000-year problem - Wikipedia
 Climate change feedback Climate change feedback is important in the understanding of global warming because feedback processes may amplify or diminish the effect of each climate forcing, and so play an important part in dete... Climate change feedback - Wikipedia
