My understanding is that it most definitely is partly natural.
Of course, it is partially natural. But the natural effects right now are either changing by insignificant amounts or changing by tiny amounts in the direction of cooling (e.g., the sun energy contribution).
But the rapid increase in average temperature is definitely, for sure, really, really
not from natural causes.
Your reply to Dredge should have been:
What parts are natural? How big is their effect and in which direction? How do you know?
That is how you need to carry on this kind of discussion. Take it as a learning opportunity for you.
