It was not the plant life we use to sustain ourselves.

During the early periods a great deal of CO2 was in the air (volcano activity over many millions of years) and pulled out by various non-flowering plants and stored in the ground. We call the storage today “coal”. The marine plants that accumulated into piles at the bottom of anoxic oceans became the source rock for oil.

In both cases, the plant life that did this was not what we use to sustain ourselves. Furthermore, we rely on cool adapted animals (both in the sea and on the land) for our food and other material.

If you want to return to the age where jellyfish and squid ruled the seas, large reptiles lived on very warm land, and cockroaches could roam all the way to the poles… I guess you are in luck, for that seems to be where we (collectively) want to head.

Umm…that would require a global temperature increase of 20 degrees C to equal the temps that obtained when those were our terrestrial conditions.

Not even the most alarmist predictions remotely approach that.
