There's an opinion piece in the March issue of Physics Today entitled Is climate sensitive to solar variability? showing that a technique for complexity matching between statistics for solar flares and the 11-year modulation of the global temperature anomaly shows a high correlation between the two.

That modulation -- a fairly periodic signal, one up and one down roughly every 11 years -- is one of many inputs to the global temperature anomaly. When you take out all the periodic signals, you're left with an upward trend, which is the signal of global warming. The 11-year modulation is noise.

It is important to know where all the noise comes from -- all the better to understand the system and better force predictive models.

But the authors generalize their results to be proof that all "global warming" is due to the noise. And that's where the problem lies: in an effort to disprove global climate change, the authors take a valid and interesting scientific result and misconstrue it, to the detriment of us all.
