I mean per the other response that is how you build models like this aka yes, all of them. Source: Am a Statistician edit: that doesn't mean they are correct going forward necessarily and most of the doomsday models I've seen are simulations that run thousands of times and a very small number of the simulations predict doom and a very small number predict no effects. The average of these expiriments is often the most likely scenario but doesn't really make headlines.
