I think it's more about the way we communicate model results. In the media, it's communicated as absolutes like "The ice caps will be gone by 2100!"

In reality, the model results are communicated in uncertainty. More akin to "There's a 70% chance the ice caps will be gone by 2100 if the current level of CO2 emissions are not abated." That's a much less sexy headline to say nothing about the fact that most people wouldn't be shocked if a 3 in 10 chance event actually happens. Nate Silver does a much better job explaining this in his book "The Signal and the Noise"
