Global Warming Models Deeply Flawed

Ross McKitrick notes at the Financial Post that the global warming models are deeply flawed as shown by actual temperature measurements. Since the 1990s, atmospheric carbon dioxide rose by 12% from 355 to 396 ppm. According to the models, global temperatures should have risen by 0.2 to 0.9 degrees Celsius over the same time period, but actually only increased by 0.1 C, which, McKitrick states was within the margin of error of zero. More damning, though, is that the tropics should show the most rapid greenhouse warming, but have had virtually no temperature change for over 30 years.

He concludes:
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.)
