You may be aware that horticulturists add CO2 to greenhouses, boosting the level of this deadly pollutant in make the plants grow both faster and more lush. Some pollutant huh?
On the basis of this reality, I have seen a few articles expressing puzzlement that a consequence of all this nasty anthropogenic CO2 stuff will be reduced agricultural production, leading us all to get a little hungry bye and bye. Personally? I have always thought this was a load of scaremongering twaddle, worth as much as a bucket of foetid dingos kidneys.
Try this, with or without warming -
