What we have, as I understand it, is computer models that attempt to predict behaviours.

Those models that produce predictions closest to what is observed in the current and historical records gain some level of credibility. Those that don't are improved or discarded.

What we describe as "fact" might better be called "our best projections." And the consequences of them are dire for quality of life as we have known it.

Perhaps there are people here looking forward to the day they can leave behind life in Europe or America or Australia for the hot climates, diseases, and lifestyles of Ethiopia or Somalia or Uganda. I don't count myself among them.
