L' assunto e il dedotto

Computer che sfornano modelli di global warming, amen. Ma quali sono le assunzioni?

A volte l' approfondimento di qualche sito riserva sorprese:

"The modelers
begin with certain assumptions about climate that they build into the model. For
example, the computers themselves don’t somehow decide if CO2 is a more
important forcing on the climate than solar activity – the modelers, by the
assumptions the feed into the model, decide these things. The models return the
result that CO2 is the most important driver of climate in the coming century
because their programmers built them with that assumption, not because the model
somehow sorts through different inputs and comes up with the key drivers on its
own"
