AP claim:’Intricate calculations’ that take ‘months to complete’ can find ‘fingerprints of man-made climate change’
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. Those could take weeks or months to complete, and then even longer to be checked by other scientists. In general, though, climate scientists agree that future storms will dump much more rain than the same size storms did in the past."
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.'
The real way they find the "fingerprint" of CO2:
