A visual representation of the five main ice ages that the planet has went through; with the colour palette of each image signifying the severity of the age it is portraying. As such, the present age we are experiencing is of a much warmer tone than the others due to the relative height in temperature through both natural and human causes. The ages, in order, are as follows: Huronian, Cryogenian, Andean-Saharan, Karoo, and Quatenary. Back to Photography.
