I don't think I have ever seen a scientific prediction that New York would be under 100 feet of water by now. You said "every prediction", but I guess you just meant some predictions. What do you think of the shrinking polar ice cap, melting permafrost, receding glaciers, etc.? All of these point to a warming climate. These have been predicted by computer models.
What are some of the computer models and major predictions that have been proven laughably wrong?
