The real world will still be altered, and no matter what economic model you employ, that will not change.
But the question is why should we care? If the economic impacts of the change are minimal then there is absolutely no justification for doing anything. We should just adapt. If the economic impacts are large then a case can be made for action depending on the cost relative to the economic impacts.
Bottom line: it is simply impossible to make any decision on what to do about the science without using economic models. That is why it is simply moronic to scream "denier" whenever someone disagrees with the outputs of the economic models that you prefer only because they suit your political preferences.
The model the squid was talking about earlier is artificial, but it is the friggen model that your fake economists use, you know the ones that you spread your fear mongering about.
Nothing but hypocritical special pleading. i.e. the economic models you like are good and should be heeded. The models I like are "fake". Are you really so lacking in self awareness that you are unable to see the contradictory nature of your argument?
