Malthus’ predictions were proven incorrect. The predictions of climate models — less rainfall, increased temperatures, less arable land — have proven correct. Not to mention that observable behavior matches those same models. If anything, the models have understated the direness of the situation: both the Arctic and Antarctica are warming far faster than even the most pessimistic models predicted.

You are claiming that because one man was wrong that all men are wrong. That is dangerously absurd.
