I know very well what isotopes are. As well as isomers, allotropes, and other types of chemical/physical variants. And you're misrepresenting how such are used and what that means. Few question that human activity has increased CO2 levels.
I've already embarrassed Numbers over this several times now but I guess it's hard for him to let go of the religious fables that he's been told.
