You're asking loaded questions based on the assumptions forwarded by interest groups... I honestly don't know how else to answer.
I think that we can agree that the Earth's climate is a hugely complex system affected by variables inside our atmosphere, deep within the Earth and outside our terrestrial atmosphere... Assuming that you would agree with this ideal, you can understand how it is ridiculous to believe that it is possible to boil-down this complex system(s) into one or two simple cause/effect relationships.
Can we agree on this?
I can't agree on it's warming "just because".
Sorry.
