I don't think I understand the point you are making about climate change deniers and conspiracy theorists. It seems to me that the article is consistent with the two points you made. The implication of the article is that the extra CO2 in the atmosphere gives this plant an extra edge of other plants because the plants use it to produce more growth inhibiting chemicals rather than only growing more. As a result, in the presence of these plants, crops do not get the benefit of the extra CO2, because their growth is inhibited by the extra inhibitors more than the extra CO2 makes them grow.

Let me be more clear. The tone of the article and the menacing on the Title made me uncomfortable. I don't understand why we have to resort to fear instead of reason on important issues.

Parthenium hysterophorus is now being reported from India as a serious problem in cotton, groundnuts, potatoes and sorghum, as well as in more traditional crops such as okra (Abelmoschus esculentus), brinjal (Solanum melongena), chickpea and sesame (Kohli and Rani, 1994), and is also proving to be problematic in a range of orchard crops, including vineyards, olives, cashew, coconut, guava, mango and papaya (Tripathi et al., 1991; Mahadevappa, 1997; Gnanavel, 2013). They are not fear mongering. This is a calm, evidence based, bit of research about a very worrying species.
