Well, considering that we had only been in the cold PDO phase for 15 years and the warm AMO phase for 14 years, no one should have expected that the respective cycles were changing phases last decade. Looking back throughout history into the 1800s, there have always been smaller scale fluctuations that were counter to the concurrent multidecadal trend. As for CC altering the versions of the cycles as we know them, talk to me in 10 years, but for now that is something straight out of a Rod Sterling adaptation.
