More accurately. The science of Climate Change is today roughly where the science of cigarette smoke was in 1984 when the Surgeon Generals warning label was mandated stating "Smoking Causes Lung Cancer, Heart Diseaz, And Emphysema." If we acknowledge that the evidence was sufficient then to justify that warning we should acknowledge that comparable evidence today justifies a similar unqualified warning. That is a bit different than what I initially wrote. I was being lazy.
