The last paragraph of your article is most interesting:

Apart from solar brightness, more subtle influences on climate from cosmic rays or the Sun's ultraviolet radiation cannot be excluded, say the authors. However, these influences cannot be confirmed, they add, because physical models for such effects are still too poorly developed.

I doubt they will ever create a model that is complex enough to model the climate accurately. Simply too many factors. The climate itself is the only model that is currently running that shows the correct output data. We need only discover the question.

I agree.
