No, Yale Climate Connections, Carbon Dioxide Does Not Harm Plants

Yale Climate Connections published an article this week attacking the scientific consensus, and implicitly calling all greenhouse operators idiots, by claiming adding carbon dioxide to the air harms plants and reduces crop production. Not surprisingly, the article, titled “More CO2 in the atmosphere hurts key plants and crops more than it helps,†offers little science to support the assertion. In reality, the scientific evidence is clear that more carbon dioxide in the air boosts plant growth and improves plant nutrients and water-use efficiency. These two facts are a primarily reason why global crop yields set new records nearly every year as CO2 levels rise and the Earth modestly warms.
While acknowledging carbon dioxide is plant food, which is why it is commonly used in greenhouses, the author of the Yale story writes, “[t]he familiar adage – too much of a good thing is a bad thing – applies to atmospheric carbon dioxide: In higher concentrations, it is a damaging pollutant.†However, most plants evolved with carbon dioxide levels were significantly higher than at present and under no realistic emission scenario will atmospheric carbon dioxide reach levels at which plant growth is harmed.
