Scientist did great work in understanding the role of CO2 in photosynthesis in the 1920’s

They used the scientific method and empirical evidence to ascertain the benefits of increased CO2

From evidence of widespread forests when there was an abundance of CO2, to increasing food productivity – just ask any greenhouse operator on the use of CO2.

The benefit of increased C02 is no secret.

But now thanks to climate models it turns out this may not be true… or only have a kernel of truth to it.

My favourite line is that weeds will grow more too. While claiming plants won’t necessarily grow better.
