Hah, not that I'm saying that this guy's other views have anything to do with his ideas on climatology, but the paragraph after the one you linked is titled "Racial Biology." It doesn't end well: "...and the results formed the scientific basis for the Compulsory sterilization program in Sweden, as well as inspiring the Nazi eugenics in Germany."
Don't nobody jump down my throat or anything, the juxtaposition just made me laugh.
