Cause of pause is perplexing

If the ocean and the trade winds caused the pause in global warming, would it be possible if these same factors caused global warming? A quick check of Google on the causes of the current global warming pause brings up various causes.
1) Lower solar activity: our local star cycle is about half the strength of the previous ones. (Journal of Atmospheric & Climate Sciences)
2) All the heat is hiding in the deep ocean. How it got there without the ARGO buoy system picking up the transfer of heat between the ocean water layers is of course a mystery. (Earth's Future)
3) Because of the reduction in CFCs the global warming stopped. (Nature Magazine)
4) Volcanic eruptions caused a lot of sulfur dioxide and therefore halted global warming. (Geophysical Research letters)
5) Stratospheric water vapour changes slowed the increase in global warming. (Science Magazine)
Finally, in the latest from NASA's Dr. Gavin Schmidt, it was a coincidental combination of these and other factors that caused the pause.
Not being a scientist or anything, I am still wondering how all these different reasons enumerated above can be reconciled with the idea that the whole global warming science is settled. Just asking.
