Seth Borenstein: "There's a scientifically accepted method for determining if some wild weather event has the fingerprints of man-made climate change, and it involves intricate calculations.

Climate Depot Response: AP's Seth Borenstein claims there is some kind of arcane black box that finds fingerprint of man-made global warming! This coveted climate black box is only available to select few: Michael Mann, Michael Oppenheimer, Kerry Emanuel, Katharine Hayhoe, Kevin Trenberth, etc.
Climatologist Dr. Roy Spencer pans – Part of report ‘is just simply made up’ – ‘There is no fingerprint of human-caused versus naturally-caused climate change’ To claim the changes are “unprecedented” cannot be demonstrated with reliable data, and are contradicted by some published paleoclimate data which suggests most centuries experience substantial warming or cooling.'
MIT Climate Scientist Dr. Richard Lindzen: Believing CO2 controls the climate ‘is pretty close to believing in magic’
The real way they find the "fingerprint" of CO2:
