Irrelevancies/nobody can predict the future
|Irrelevant Comment: Nobody can predict the future.|
This claim is most commonly used to argue against global warming predictions, with the implied conclusion that we shouldn't be worrying about what a few Cassandras (a.k.a. 97% of climate scientists) are saying because they "don't know" what will really happen.
This is such a transparently silly argument that it's hardly worth addressing, but just so we don't have to keep rehashing this:
Our lives depend on making accurate judgements about uncertainties. When all the available evidence points strongly to a particular prediction, it would be idiotic to act as if the future was no more certain than a coin-flip.
