Hello All,

I'm preparing a response. I've just got the relevant part of the MM2005c
(Energy and Environment) software working and the surprising conclusion
is that they no only overlooked the standardisation stage but also failed to
centre the data. This is relected in Figure 2 of the Energy and Environment
paper which shows the first PC to oscillate aroubnd 0.04 -- the mean of this
PC is much greater than its variability. Data is usuall centred, of course,
because otherwise the mean values dominate the first PC, which is what is
happening here. I'll get a comment to this effect up on the CPD site by the
end of today. (I was on leave yesterday, hence the delay in responding).

There is a mistake in the manuscript at the point McIntyre cites, it should be
MM2005c (the EE paper) not MM2005 (the GRL paper) which was referred to there.
The software for the EE paper is now available on his site, as he indicates,
since March this year, but is still not linked to from anywhere.
Nevertheless, I will apologise for the inaccuracy and correct the comments
on the basis of what his code actually does,
