The National Research Council, like the official SPM, affirms that recent warming really does appear anomalous in light of the past millennium. The Fraser report obscures this point by cleansing the recent period of warming from their graphs. The discussion of solar variability consists of a lot of vague talk about unexplored possibilities, while skirting the basic problem with solar variability as an explanation of recent warming: There is no observed trend in solar activity of a type that could explain recent warming, and if the problem were an unobserved trend in solar ultraviolet, it would make the stratosphere (where UV is absorbed by ozone) trend warmer relative to a constant-solar baseline. In reality, the stratosphere is cooling strongly, and at about the rate the models predict.
