"how much of that warming was due to natural cycles I wonder? no one seems to bother with that"
oh, sure, because you say so?
The science has studied solar cycles, ocean oscillations, and other natural cycles, including orbital changes and the like.
Yet you come up with that statement?
What the scientists find is that natural variation should have seen some planetary cooling. So MORE than all the current warming is due to CO2, because it has offset that natural cooling.
