- The climate was warmer, with little to no ice caps
- The Eocene Epoch was the warmest, with many animals living in polar regions
- Tropical areas are thought to be the same temperature as they are now
- Now, carbon dioxide is increasing from human activity, harming the ozone

# data[].attributes.body
- Plant and animal life was huge, increasing oxygen levels to 35%
- Forest and swamps formed. Plants and animals died in masses, CO2 actually decreased, cooling earth.
- Dead matter over time became coal that we use today.

- Photosynthesis cleared the methane in the air
- Oxygen in the air oxidized iron, making redbeds of iron oxide
- The new oxygen gave way to the Cambrian explosion with new marine life.
- In the later years of this time period, we start to see small plants and invertebrates, and four-footed animals.

# data[].attributes.body
- Cyanobacteria developed, photosynthesizing and creating free oxygen
- All of the photo synthesis made Earth's atmospheric oxygen content increase, and the carbon dioxide decrease.

- Molten surface with gases from volcanoes
- Atmosphere mostly hydrogen, sulfide, methane, and up to 200 times the amount of carbon dioxide in today's atmosphere
