Maybe we should go by scientific facts? plants thrive in warmer climate and higher CO2 levels, not in colder climate and at starvation levels of CO2. I suggest you look into the operations of commercial greenhouses, then study the temperature and CO2 records matching the origin and evolution of plants going back to hundreds of millions of years ago.

Yes, I certainly think we should follow basic logic. I worked at a greenhouse. Historical data is obviously not based on current plant genetics. Do you think people use a greenhouse in midsummer? There is clearly a maximum temperature that varies for different plants. I suggest you look up the thermodynamics of CO2.

Yes, there are many commercial greenhouses that operate year-round, including the summer months. The deliberately increased level of CO2 in a commercial greenhouse has no measurable thermodynamic impact.
