They even switched, after long insisting that man-made warming was incontrovertible and only boobs and hacks denied it, to touting nebulous “anthropogenic climate change” that calls all weather proof of a coming apocalypse. They were not developed by feeding in known past conditions, successfully predicting known past outcomes, then feeding in present conditions and saying judge us by the accuracy of the results. We know a lot about what happened in Earth’s history, including frequent bouts of spectacular, worrying climate instability. But we know very little about why, except it cannot have resulted from human action because most “climate change” happened not just before industrialization but before anatomically modern humans. But no model can say why without so much kluging that it cannot be applied to 2017 or any other period.
