Ea water molecules that contain heavy oxygen
Since sea water molecules that contain heavy oxygen evaporate at different rates at different temperatures, in comparison with normal water, the oxygen-18 ratio presents itself as a highly reliable proxy for measuring historic temperature patterns as far back in time as 500 million years. The existence of the 31 million years resonance cycle, and the 150 million years resonance cycles, has been discovered in this laboriously reconstructed climate record.
