Ice is quite an unusual substance on Earth; for over 90% of our planet’s life has been completely ice free. Ice ages occur around every 200 million years or so and last around 10 million years. The one we’re currently in started around 2 million years ago and we’re due another period of glaciation where the ice caps will encroach again. But a race is on between the cooling effect of fluctuations in the Earth’s orbit and the warming effect of our expedient release of carbon into the atmosphere. Will it be freezing or flooding?
