282E-296-Tilted History

Seasons are created by the fact that the Earth's axis of rotation is currently tilted 23 1/2 degrees relative to our path around the Sun. The slight out of roundness of the Earth's orbit combined with a 41,000 year cycle in its 3 degree axis of rotation wobble can cause the Earth's climate to change on very long time scales. Turns out that these astronomical cycles are likely to be the drivers of where you are from and where you live.
