THIS is how you test how accurate models actually are. The fact that you think that particular graph means all climate models are terrible (and the fact that you think it's a big deal that they tune models to fit past data, as that is the CORE of modeling in general) tells me all I need to know about how much you know about forecasting models. Which is obviously not much. (Note: my knowledge isn't about the specifics of climate change models, so I don't know exactly how much weight they put on various factors; my knowledge is about forecasting models in general and my specialty was population modeling).
