    4 Conclusion
    We have shown a strong correlation between solar and 
    tropospheric variability, in that swings from El Ni˜no 
    to La Ni˜na are related to the phase of the solar 
    cycle’s “fiducial clock,” and that that clock does not 
    run from the canonical solar minimum or maximum, but 
    instead resets when all old cycle flux is gone from the 
    solar disk. While the exact mechanism remains to be 
    elucidated, changes in cosmic ray flux appear to the be
    the driver of these ENSO swings.
    
    Finally, in the absence of sensitivity to solar-driven CRF 
    variations in current coupled climate models, we have a year 
    or so to wait to see if this indicator pans out. However,
    should the coming terminator be followed by such an ENSO 
    swing then we must seriously consider the capability of 
    coupled global terrestrial modeling efforts to capture
    “step-function” events, and assess how complex the Sun-Earth 
    connection is, with particular attention to the relationship 
    between incoming cosmic rays and clouds/ precipitation over 
    our oceans.

This is a great paper actually. It depends directly on the premise that cosmic rays cause drastic changes in cloud microphysics. The proof presented for this is a statistical correlation between termination points of sun activity and ENSO (El Nino, La Nina).

They plan to establish causation by predicting ENSO changes based on solar activity, which is good. Once they do that, they will need to prove that cosmic rays are more important in cloud microphysics than the CERN CLOUD experiments suggests so far.

This is what real science is. Great find.
