“The impact of doubling the CO2 in the atmosphere from 405 parts per million to 820 parts per million IS ZERO.”
Actually there will be a major impact ... Flora will flourish globally thanks to having more airborne 'food'
The level of 1000 PPM CO2 is very close to the optimum level of CO2 required, given no other limiting factor, 1200 PPM, to allow a plant to photosynthesis at the maximum rate.
Hi Peter, the models were flawed to begin with. I discuss this for the Club of Rome's 1st mandated book The Limits to Growth (1972):
