Ross McKitrick has a must-read article in the Financial Post, looking at climate models and their environmentalist-like divergence from reality:
The IPCC must take everybody for fools. Its own graph shows that observed temperatures are not within the uncertainty range of projections; they have fallen below the bottom of the entire span. Nor do models simulate surface warming trends accurately; instead they grossly exaggerate them. (Nor do they match them on regional scales, where the fit is typically no better than random numbers.)
