Snow Ball Earth between 750 and 600 million years ago.
2 Billion years ago O2 began forming in the atmosphere
CO2 has been a driver of Climate for Millions of years. (phanerozoic 550 Mya to present) There have been large ice sheets during the Phanerozoic ~300 Mya Our present Ice age began around 2 MYa
Most of the past 200 Myr has been very warm and dominate by a greenhouse Earth. Our present state (the Pliestocene began about 2 Myr ago)
K-T boundary ~ 65 Million years ago. End of Dinosaurs. Evidence suggests Asteroid impact cause global cooling for several years
