(This arises from the simplistic assumption that a correlation necessarily means causation - which, in any case, can be interpreted either way - is increase in CO2 since the 18th century the CAUSE of the increase in general temperature by the 21st century? - or is the rise in global temperature the cause of the increase in CO2? - solubility in the vast amount of water covering 2/3rds of the world' surface area will DECREASE with rising temperature).

Every horticulturalist is well aware that increase of atmospheric CO2, for example in closed greenhouses, gives rise to increased plant, flower and fruit production (cf. new developments in tomato production at British Sugar's vast refinery at Wissington in Norfolk).

It may surprise you to learn that most have us have applied a great deal
of critical thinking to this problem and found the science of the IPCC
The science is far more than a simple computer model of atmospheric CO2
and your statement to that effect almost had me ignoring this screed
since you do not appear to be well enough informed on the issue to have
an informed debate. Ill conceived screeds are generally best ignored.
The "power-that-be" have spent 50 years trying to cloud this issue with
pseudoscience and unfounded doubt and it is most disappointing to see a
food scientist offer them material support in that endeavor.
