In the Jurassic age there were no fossil fuels! All the organic carbon was circulating around the environment. Resulting me there was 65% more life on earth. Though global photosynthesis was less evolved, and left a larger trace of carbon dioxide in the air.
For last two centuries modern photosynthesis has strictly limited global carbon dioxide to only two parts per million. The 0.0004% additional carbon dioxide every day has resulted in more life on earth. Gradually restoring the Jurassic Life in modern biological form.
The sea levels in the Jurassic were 60 metres lower. More plant and animal life ties up rain fall to prevent it from the back into the seas. Rain comes from evaporation over the seas. So more life means lower seas.
The Jurassic had four parts per 1,000,000 carbon dioxide in the global air. Photosynthesis drives life both are over the land and in the seas. Droughts have no effect. Photosynthesis is in total control of carbon dioxide levels.
In the Jurassic there were three natural ice ages! When carbon dioxide levels will have risen. They were at 180, 600 and 700 million years ago.
Historically carbon dioxide levels can only rise in natural ice ages. The suggestion that this gas warms the is contrary to all historical records in the rocks.
Carbon dioxide levels track the natural climate with a four year lag.
Photosynthesis evolved in the Permian age. The start of the Permian was 1000 year ice age with carbon dioxide levels at 10ppm. Then photosynthesis evolved, carbon dioxide levels crash to only 1ppm and 90% of life on earth died.
Life on earth only recovered as more animals evolved to eat plant bulk and combine it with oxygen-the waste gas excreted by plants, bacteria and algae.
