Because the latest fad amongst the voodoo shamanry known as econ Ph.Ds, especially those who have a blog in uber-liberal daily publications courtesy of a nominal gift from the status quo for valiant efforts in preserving the status quo, is to always and without fail assume that correlation is and always implies causation, we make, with the help of John Lohman, the following argument: since global leverage (via Debt-to-GDP) has a greater correlation to the "Temperature Anomaly" aka Global Warming, at 0.79, than CO2 concentration, at 0.69, it is obvious that global warming is purely a function of ever increasing leverage, and not, as is widely accepted by various ecological consultancies, carbon dioxide concentration. And now you see how easy it is to make idiotic, and totally spurious statements (which however serve as fodder for even more idiotic peer-reviewed white papers and journal submissions this keeping lots of people employed while contributing absolutely nothing to society), which given enough time, will become religion to a new breed of shamans once the old ones are forcibly kicked out of their comfortable corner offices.
