We generally expect models to have predictive value, at least through a set of historic data, before we lens them much credence. We have made an exception for climate models. I believe following basic scientific procedures is a better plan than listening to what amounts to a widely-hekd belief structure. It is particularly galling when we could be using time and effort to combat the proven environmental catastrophes such as air and water qualities, deforestation, and issues such as the one that started this thread.
