Due to natural cycles in eccentricity (shape of the Earth’s orbit path), obliquity (the angle of Earth’s axial tilt) and precession (Earths axis of rotation), the Earth goes through periods of glacial and interglacial periods.
Glacial periods are marked by colder temperatures and glacial advance. Interglacial periods are marked by warmer temperatures and glacial retreat.
Glacial advance and retreat have occurred within natural cycles in the past, but there are growing concerns relating to the anthropogenic temperature increase and melting of glacial ice due to global warming in the 21st Century.
