This disclaimer is not a free card to cast doubts on climate change science. Not being pro fossil fuels usage has nothing to do with questions about climate change science. The way you raise that disclaimer to doubt climate change science ? Well...
People have given you simple explanations you dismissed, I am giving you links to longer/harder explanations you are dismissing (I presume, since you don't follow on that).
If you think climate change science is wrong then bring up why you think so. "What if it's wrong" is rarely a useful basis by itself for a discussion on topics that have been studied in depths for decades.
