On ‘belief’ and ‘denial’ : Comments
By Don Aitkin, published 27/12/2012Further, the doomsayers accuse old-fashioned empiricists like me of being 'deniers' or 'denialists' because we do not accept their faith.

You link, again [!] to Sks without a clue what you are connecting to, in this case the critique of the McLean paper about natural variability, ENSO, and its trend creation potential.
McLean has been vindicated:
http://journals.ametsoc.org/doi/abs/10.1175/JCLI-D-11-00148.1?journalCode=clim
Whereas Foster [ie Tamino] has been proven wrong; Foster, as well as criticising McLean et al directly, attempted to prove AGW caused trend by doing the opposite of what McLean had done; that is, detrend variability, whereas McLean had detrended AGW: see:
http://iopscience.iop.org/1748-9326/6/4/044022
Foster and his mate, Rahmstorf [F&R] attempt to isolate the AGW temperature signature by removing the natural factors; so they remove MEI [ENSO], volcanoes [AOD] and the sun [PMOD]. According to their 2nd equation;
GISS = -91.43 + 1.024Trend + 0.0761MEI(4m lag) + 0.06694TSI.PMOD(1m lag)- 2.334AOD (7m lag)
(1) GISS = 1.024Trend + bx + c
(2) GISS = 1.0Trend + 0.024Trend + bx + c
(3) GISS = (GISS + d) + 0.024Trend + bx + c
(because y = mx + d, where m=slope=trend, d=y intercept)
(4) 0 = 0.024Trend + bx + e
(5) Trend = -(bx + e)/0.024
F&R have not solved for GISS. By including Trend(GISS) as an independent variable they have eliminated GISS. What they have shown is that the Trend in GISS can be fully explained as a linear result of MEI, TSI, and AOD, without any reference to CO2.
In other words, F&R have proven that Climate Change is fully explained by the Multivariate ENSO Index (MEI), the Total Solar Irradiance (PMOD), and the Volcanic Aerosol Optical Depth data (AOD).
In other words, F&R have proven that CO2 has no role in climate change.
Do you understand that Poirot; until you do you will not appreciate that your heros, the climate scientists, have feet of clay
