No, I am not a scientist. However, I know enough about it to know how it is done. The climatologists do form hypotheses and they test them against the data. And guess what! The hypotheses say that global temperatures should rise AND THE DATA CONFIRMS IT! It would seem that the term "greenhouse gasses" mean nothing to you.

It is clear that your actual objection, like that of other conservatives, is purely political (and you are afraid that doing something about global warming may discomfit your way of life). Arguing with you is like arguing with creationists; Neither one of you let mere facts change your minds.
