claim: Postma's model contains many simple errors; in no way does Postma undermine the existence or necessity of the greenhouse effect.
evidence: Since it is absurd to have no logical method for settling on one hypothesis amongst an infinite number of equally data-compliant hypotheses, we should choose the simplest theory : Either science is irrational [ in the way it judges theories and predictions probable ] or the principle of simplicity is a fundamental synthetic a priori truth.
