Do you see how the claim that "humans cause global warming" differs from the claim quoted in the grandparent comment?

It takes the form of a premise in a sentence that goes on to use it as an illustration of another known problem that isn't realistically going to be solved any time soon. I don't think I accept your implication here and in my judgement you introduced politics, not the opening post and so it is your comment that I would wish to see discouraged.
