WebMilankovitch cycles explain the creation of the ice ages. Think about Eccentricity. In order for the ice sheets to grow enough to create an ice age, you need "summer" to happen when the earth is furthest away from the sun (cooler summers, little ice melt) and "winter" to appear when the earth is nearest the sun (lots of fluffy snow to build up). Precession does affect seasonal timing relative to Earth's closest/farthest points around the Sun. However, the modern calendar system ties itself to the seasons, and so, for example, the Northern Hemisphere winter will never occur in July.

http://www.extinctiontheory.com/how-precession-causes-climate-change/ WebFeb 13, 2013 · The seasons are mainly due to the 23.5° tilt of the axis of the Earth as it moves around the Sun. It is summer in the southern hemisphere when that half of the Earth is tilted towards the Sun. Six months later the Earth is on the other side of the Sun and so it is summer in the northern hemisphere as that is then tilted towards the Sun. grand boulevard lofts
