I don't think scientists really understand exactly how magnetism or
gravity works, for sure. I don't think doctors understand completely
how the human body works, but they still plug along and were certainly
better off with them, than without them. One doesn't need absolute
knowledge and 100% certainty before you do anything. We simply look at
the probabilities and the evidence and the consensus of professional,
reputable, climate scientists and we go from there.
