Well I think the point is our CO2 emissions fluctuate. The trend may be flat-lining on 2005 levels or down on 2005 levels, but then you get the smart little Tufton street types that come along saying "see they're lying about the data, because theres all these peaks and troughs!" casually ignoring the fact that CO2 emissions generally go up in winter due to heating. At least in cold countries, for Australia maybe the opposite is true, I haven't looked specifically.
