I think any forecasting has a bit of science to it and a bit of anything but. The results from any model are going to depend on the assumptions you make with regard to them. The recent predictions for hurricane seasons (the last two years) have been way off. Predicting the weather in two weeks, requires assumptions to be made with regard to how air masses are going to move, and they rarely move exactly as expected for such a long period. Dragging those predictions out over long periods, i.e. decades, is something science has not been trying to do for that long. The earth, however, has been warming up for about 18,000 years. Do we understand why? Do we really get why the earth has had ice ages or periods when lots of it was almost tropical? I don't think so, from what I've read. So, if why global temperatures have changed in the past is not understood, how are changes going to be predicted?

The earth has gone through several periods when the climate has been much colder and several when it has been warmer than it is now. My one prediction is that I bet both happen again.

As far as the original question, yes. Yes, you should be prepared for possible scenarios invovling high winds, because in the case of many storms, the wind is what does a lot of damage. If only rain and snow caused damage, we would not have much more than flooding, which would make preparing easier.
