Keith E. Idso is a botanist and vice president of the Center for the Study of Carbon Dioxide and Global Change.
In 1994, Idso, along with his father, published a review paper on the topic of increased CO2 levels and their effects on plant growth.
The paper concluded that not only did other factors not diminish the ability of CO2 to increase plant growth rates, that "the data show the relative growth-enhancing effects of atmospheric CO2 enrichment to be greatest when resource limitations and environmental stresses are most severe.
"[1] As of 1999, he was teaching biology in the Maricopa County Community College District as an adjunct professor,[2] a post to which he was appointed in 1996.
His talk was entitled "Direct Biological Effects of Increasing Levels of Atmospheric Carbon Dioxide.
