I'm not convinced that we have a good model for climate, either. I think we do not have any clue about large-scale cycles in the climate. Nobody predicted the long drought in California, but the Southwest has had a bunch of cyclical droughts over the past 1000 years. This year was supposed to be a La Nina year for California, but instead something else happened and there has been three years' worth of rain in northern California instead.
