Another denier argument. All models are far from infallible. They're models; an imperfect representation and they always will be since, at least in this universe, since it is impossible to obtain perfect information about a system. The aerodynamic models for jet aircraft are wrong. The models for bridge and building stability are wrong. Every single one of them are wrong. However, just because a model is wrong doesn't mean it isn't useful. All models have errors, and by accounting for those errors a model will still yield predictive skill. Error analysis is very important in modeling and is used constantly to establish everything from structural integrity limits to likelihoods of future droughts. It's a fundamental component of numerical analysis.
That's not a denier argument. It's perfectly valid to question the models. Just because our "best available evidence" leans one way doesn't make it 100% infallible proof. Not too long ago, scientists figured out they were vastly overstating temperatures over time because they didn't fully understand the heat sinking capability of the oceans (the whole "where's the missing heat?" debate). That variable alone completely rewrote the book on future projections of climate based on current CO2 numbers. Denying global warming may be dumb, but questioning the suppositions and conclusions drawn from the current level of "100% faith in the models" is another. I give different levels of credence to "string theory" and "quantum physics" and "gravity" and "evolution" for very good reasons. Some are rock solid with hoards of reproducible evidence and sustainable models. Others are borderline guesses with models changing annually. Stop pretending that the current "best guess" of scientists is infallible proof.
