And yet people like Odious have turned climate science into the religious belief system we see today.Science is a process for finding how how stuff works in the real world. It is not "the truth", but it is the most effective way of finding out the truth. It makes mistakes, but has amazing powers of self-correction.
Climate science is not more or less variable than any branch of physics, chemistry or biology. In fact, parts of biology like genetics may be more complex.
Very few branches of science are reducible to a simple formula.
