labelled ‘sunspot numbers’ and ‘Grain price’ while the vertical axes are labelled ‘number of sunspots’ (meaningless unless the time interval specified) and ‘W/m2’ — a novel unit for grain prices. However, Tim Lambert’s comparison with the original source [figure

      in reference 550] reveals a more complicated degree of falsification: i: The curve reproduced as Sunspot numbers is ‘solar insolation’ (Sonneneinstrahlung in the reference 550) and is quantified on the right-hand axis which has the same numerical values as in Heaven + Earth in W/m2. ii: In the original, the left hand axis is prices, Getreidepreise (Mariengroshchen pro 100 kg), with the range 100 to 200, i.e. the numbers that Plimer relabels as Number of sunspots.

    p. 131, figure 15: This has multiple problems: i: unidentified source and data; ii: selective data use; iii: Incorrect description in caption [item 39]; iv: highly smoothed CO2 record added for comparisons; v: erroneous statement about correlations.

    p. 131, figure 15 (caption): Plot of the last 140 years . . . no it isn’t. The plots, starting at 1860 end a little after 1980 (although the time axis extends beyond 2000). Truncating the plots in this way serves to reduce the correlation between temperature and CO2 and enhance the correlation between temperature and sunspot cycle length.

    p. 132: Greenhouse gases act only as amplifiers. In using the word only, Plimer fails to explain how greenhouse gases can have a (amplifying) warming effect when the gas increase is due to other climate change (as in the mainstream interpretation of glacial- interglacial cycles) and yet not have a warming effect when the gas increases are due to human inputs.

(2003). This paper did not provide any specific satellite-derived estimate of the effect of CO2. .
