For the past three million years, Earth has been in an 'Icehouse' characterised by alternating glacial and interglacial periods. "Now that we have succeeded in capturing the natural climate variability, we can see the projected anthropogenic warming will be much greater than that." Higher CO2 and little-to-no global ice volume is seen during the Hothouse and Warmhouse compared to the Coolhouse and Icehouse. The CENOGRID is the clearest and most accurate view of past climate conditions to date, providing information about past deep-sea temperatures, global ice volumes and the carbon cycle. "While we show the Earth previously experienced warm climate states, these were characterised by extreme climate events and were radically different from our modern world.
