Climatologists are not mechanical engineers, they are PhD's. I agree, engineers are very careful about the details. However, PhD's don't have life-risk to consider. I fact, there is overt manipulation of the data upon which most (if not all) of the climate "conclusions" are based.
Further, engineers don't have the luxury of being influenced by confirmation biases or other cognitive issues.... because engineering data is wholly-objective and extremely repeatable. "climate science" is neither; the inductive processes they apply seem to lead down paths that would follow confirmation bias, repeatedly. I'm involved in science and a great mentor of mine once said that, "if you torture the data enough, it will tell you anything you want to hear...."
