CO2 enrichment wouldn’t make plants flourish. Plants have to have CO2, obviously, but they flourish just fine with our current 150 to 300 ppm. Plants flourish from adequate sunlight and water, provided the temps are suitable (the higher up in latitude or altitude, the fewer the plants).

Also, if you’ve seen the movie “Apollo 13”, you know that too much CO2 causes brain asphyxia.

CO₂ enrichment does make plants florish. Plants inhale CO₂ and exhale Oxygen. While plants do fine in our current atmosphere they do better in a Carbon Dioxide rich environment.

Not to be argumentative but inquisitive. It is my understanding that the high CO2 levels were accompanied by higher (than current) temperatures. As far as asphyxia, would the location of a dinosaurs brain (deep in a very large head), and being about the size of a walnut, counter this in any way?
