""If there is climate change, some of it may be due to our actions""

To take a reasonable approach, maybe so? But, would it not be just as reasonable to consider very much could be due to our actions, as none of it is due to human actions?

I agree that to engourage reasoned discussion, thread posters should select non-provoking titles. I suspect some chosen are tit-for-tat reasons,   stimulated by similar ones in the past.
