The article is typical of this kind of nonsense, full of qualifiers, as in “…understanding any link between planetary warming and extreme cold remains a work in progress,” and …observations of jet stream patterns have not confirmed the hypothesis.” and “there’s still a lot of mixed feelings in the scientific community, though there is some tantalizing evidence that there is some ‘there’ there.”
