    "While we can definitively say this weakening is happening, we are unable to say to what extent it is related to climate change or whether it is a natural variation," Piecuch said. "We can see similar weakening indicated in climate models, but for this paper we were not able to put together the observational evidence that would really allow us to pinpoint the cause of the observed decline."

    What observational evidence would prove it either way?

      The scope of the study wasn't wide enough to get definitive evidence that it was man-made climate change based, or simply natural periodicity of climate zones. The Earth has a shit load of climate data over thousands of years to sift through, and that costs money which may be outside of the budget of the study.
